AFP.CONF(5)			    3.1.12			   AFP.CONF(5)

       afp.conf	- Netatalk configuration file

       The afp.conf file is the	configuration file for the Netatalk AFP	file

       All AFP specific	configuration and AFP volume definitions are done via
       this file.

       The file	consists of sections and parameters. A section begins with the
       name of the section in square brackets and continues until the next
       section begins. Sections	contain	parameters of the form:

	       name = value

       The file	is line-based -	that is, each newline-terminated line
       represents either a comment, a section name or a	parameter.

       Section and parameter names are case sensitive.

       Only the	first equals sign in a parameter is significant. Whitespace
       before or after the first equals	sign is	discarded. Leading, trailing
       and internal whitespace in section and parameter	names is irrelevant.
       Leading and trailing whitespace in a parameter value is discarded.
       Internal	whitespace within a parameter value is retained	verbatim.

       Any line	beginning with a semicolon (";") or a hash ("#") character is
       ignored,	as are lines containing	only whitespace.

       Any line	ending in a " \	" is continued on the next line	in the
       customary UNIX fashion.

       The values following the	equals sign in parameters are all either a
       string (no quotes needed) or a boolean, which may be given as yes/no,
       1/0 or true/false. Case is not significant in boolean values, but is
       preserved in string values. Some	items such as "file perm"s are

       The parameter include = path allows you to include one config file
       inside another. The file	is included literally, as though typed in
       place. Nested includes are not supported.

       Each section in the configuration file (except for the [Global]
       section)	describes a shared resource (known as a	"volume"). The section
       name is the name	of the volume and the parameters within	the section
       define the volume attributes and	options.

       There are two special sections, [Global]	and [Homes], which are
       described under special sections. The following notes apply to ordinary
       section descriptions.

       A volume	consists of a directory	to which access	is being given plus a
       description of the access rights	which are granted to the user of the
       service.	For volumes the	path option must specify the directory to

       Any volume section without path option is considered a vol preset which
       can be selected in other	volume sections	via the	vol preset option and
       constitutes defaults for	the volume. For	any option specified both in a
       preset and in a volume section the volume section setting completely
       substitutes the preset option.

       The access rights granted by the	server are masked by the access	rights
       granted to the specified	or guest UNIX user by the host system. The
       server does not grant more access than the host system grants.

       The following sample section defines an AFP volume. The user has	full
       access to the path /foo/bar. The	share is accessed via the share	name

	       path = /foo/bar

   The [Global]	section
       Parameters in this section apply	to the server as a whole. Parameters
       denoted by a (G)	below are must be set in this section.

   The [Homes] section
       This section enable sharing of the UNIX server user home	directories.
       Specifying an optional path parameter means that	not the	whole user
       home will be shared but the subdirectory	path. It is necessary to
       define the basedir regex	option.	It should be a regex which matches the
       parent directory	of the user homes. Parameters denoted by a (H) belong
       to volume sections. The optional	parameter home name can	be used	to
       change the AFP volume name which	$u's home by default. See below	under

       The following example illustrates this. Given all user home directories
       are stored under	/home:

		 path =	afp-data
		 basedir regex = /home

       For a user john this results in an AFP home volume with a path of

       If basedir regex	contains symlink, set the canonicalized	absolute path.
       When /home links	to /usr/home:

		 basedir regex = /usr/home

       Parameters define the specific attributes of sections.

       Some parameters are specific to the [Global] section (e.g., log type).
       All others are permissible only in volume sections. The letter G	in
       parentheses indicates that a parameter is specific to the [Global]
       section.	The letter V indicates that a parameter	can be specified in a
       volume specific section.

       You can use variables in	volume names. The use of variables in paths is
       limited to $u.

	1. if you specify an unknown variable, it will not get converted.

	2. if you specify a known variable, but	that variable doesn't have a
	   value, it will get ignored.

       The variables which can be used for substitutions are:


	   client's ip address

	   volume pathname on server

	   full	name (contents of the gecos field in the passwd	file)

	   group name


	   client's ip,	without	port

	   server name (this can be the	hostname)

	   user	name (if guest,	it is the user that guest is running as)

	   volume name

	   prints dollar sign ($)

   Authentication Options
       ad domain = DOMAIN (G)
	   Append @DOMAIN to username when authenticating. Useful in Active
	   Directory environments that otherwise would require the user	to
	   enter the full user@domain string.

       admin auth user = user (G)
	   Specifying eg "admin	auth user = root" whenever a normal user login
	   fails, afpd will try	to authenticate	as the specified admin auth
	   user. If this succeeds, a normal session is created for the
	   original connecting user. Said differently: if you know the
	   password of admin auth user,	you can	authenticate as	any other

       admin group = group (G)
	   Allows users	of a certain group to be seen as the superuser when
	   they	log in.	This option is disabled	by default.

       force user = USER (G)
	   This	specifies a UNIX user name that	will be	assigned as the
	   default user	for all	users connecting to this server. This is
	   useful for sharing files. You should	also use it carefully as using
	   it incorrectly can cause security problems.

       force group = GROUP (G)
	   This	specifies a UNIX group name that will be assigned as the
	   default primary group for all users connecting to this server.

       k5 keytab = path	(G), k5	service	= service (G), k5 realm	= realm	(G)
	   These are required if the server supports the Kerberos 5
	   authentication UAM.

       nt domain = DOMAIN (G), nt separator = SEPARATOR	(G)
	   Use for eg. winbind authentication, prepends	both strings before
	   the username	from login and then tries to authenticate with the
	   result through the available	and active UAM authentication modules.

       save password = BOOLEAN (default: yes) (G)
	   Enables or disables the ability of clients to save passwords

       set password = BOOLEAN (default:	no) (G)
	   Enables or disables the ability of clients to change	their
	   passwords via chooser or the	"connect to server" dialog.

       uam list	= uam list (G)
	   Space or comma separated list of UAMs. (The default is "").

	   The most commonly used UAMs are:
	       allows guest logins
	       ( or Allow logins with passwords
	       transmitted in the clear. (legacy)
	       allows Random Number and	Two-Way	Random Number Exchange for
	       authentication (requires	a separate file	containing the
	       passwords, either @pkgconfdir@/afppasswd	file or	the one
	       specified via "passwd file"). See afppasswd(1) for details.
	       (	or Allow Diffie-Hellman
	       eXchange	(DHX) for authentication.
	       ( or Allow Diffie-Hellman
	       eXchange	2 (DHX2) for authentication.
	       Allow Kerberos V	for authentication (optional)

       uam path	= path (G)
	   Sets	the default path for UAMs for this server (default is

   Charset Options
       With OS X Apple introduced the AFP3 protocol. One of the	big changes
       was, that AFP3 uses Unicode names encoded as Decomposed UTF-8
       (UTF8-MAC). Previous AFP/OS versions used charsets like MacRoman,
       MacCentralEurope, etc.

       To be able to serve AFP3	and older clients at the same time, afpd needs
       to be able to convert between UTF-8 and Mac charsets. Even OS X clients
       partly still rely on the	mac charset. As	there's	no way,	afpd can
       detect the codepage a pre AFP3 client uses, you have to specify it
       using the mac charset option. The default is MacRoman, which should be
       fine for	most western users.

       As afpd needs to	interact with UNIX operating system as well, it	needs
       to be able to convert from UTF8-MAC / Mac charset to the	UNIX charset.
       By default afpd uses UTF8. You can set the UNIX charset using the unix
       charset option. If you're using extended	characters in the
       configuration files for afpd, make sure your terminal matches the unix

       mac charset = CHARSET (G)/(V)
	   Specifies the Mac clients charset, e.g.  MAC_ROMAN. This is used to
	   convert strings and filenames to the	clients	codepage for OS9 and
	   Classic, i.e. for authentication and	AFP messages (SIGUSR2
	   messaging). This will also be the default for the volumes mac
	   charset. Defaults to	MAC_ROMAN.

       unix charset = CHARSET (G)
	   Specifies the servers unix charset, e.g.  ISO-8859-15 or EUC-JP.
	   This	is used	to convert strings to/from the systems locale, e.g.
	   for authentication, server messages and volume names. If LOCALE is
	   set,	the systems locale is used. Defaults to	UTF8.

       vol charset = CHARSET (G)/(V)
	   Specifies the encoding of the volumes filesystem. By	default, it is
	   the same as unix charset.

   Password Options
       passwd file = path (G)
	   Sets	the path to the	Randnum	UAM passwd file	for this server
	   (default is @pkgconfdir@/afppasswd).

       passwd minlen = number (G)
	   Sets	the minimum password length, if	supported by the UAM

   Network Options
       advertise ssh = BOOLEAN (default: no) (G)
	   Allows old Mac OS X clients (10.3.3-10.4) to	automagically
	   establish a tunneled	AFP connection through SSH. If this option is
	   set,	the server's answers to	client's FPGetSrvrInfo requests
	   contain an additional entry.	It depends on both client's settings
	   and a correctly configured and running sshd(8) on the server	to let
	   things work.

	       Setting this option is not recommended since globally
	       encrypting AFP connections via SSH will increase	the server's
	       load significantly. On the other	hand, Apple's client side
	       implementation of this feature in MacOS X versions prior	to
	       10.3.4 contained	a security flaw.

       afp interfaces =	name [name ...]	(G)
	   Specifies the network interfaces that the server should listens on.
	   The default is advertise the	first IP address of the	system,	but to
	   listen for any incoming request.

       afp listen = ip address[:port] [ip address[:port] ...] (G)
	   Specifies the IP address that the server should advertise and
	   listens to. The default is advertise	the first IP address of	the
	   system, but to listen for any incoming request. The network address
	   may be specified either in dotted-decimal format for	IPv4 or	in
	   hexadecimal format for IPv6.

	   IPv6	address	+ port combination must	use URL	the format using
	   square brackets [IPv6]:port

       afp port	= port number (G)
	   Allows a different TCP port to be used for AFP. The default is 548.
	   Also	sets the default port applied when none	specified in an	afp
	   listen option.

       cnid listen = ip	address[:port] [ip address[:port] ...] (G)
	   Specifies the IP address that the CNID server should	listen on. The
	   default is localhost:4700.

       disconnect time = number	(G)
	   Keep	disconnected AFP sessions for number hours before dropping
	   them. Default is 24 hours.

       dsireadbuf = number (G)
	   Scale factor	that determines	the size of the	DSI/TCP	readahead
	   buffer, default is 12. This is multiplies with the DSI server
	   quantum (default 1MiB) to give the size of the buffer. Increasing
	   this	value might increase throughput	in fast	local networks for
	   volume to volume copies.  Note: This	buffer is allocated per	afpd
	   child process, so specifying	large values will eat up large amount
	   of memory (buffer size * number of clients).

       fqdn = name[:port] (G)
	   Specifies a fully-qualified domain name, with an optional port.
	   This	is discarded if	the server cannot resolve it. This option is
	   not honored by AppleShare clients <=	3.8.3. This option is disabled
	   by default. Use with	caution	as this	will involve a second name
	   resolution step on the client side. Also note that afpd will
	   advertise this name:port combination	but not	automatically listen
	   to it.

       hostname	= name (G)
	   Use this instead of the result from calling hostname	for
	   determining which IP	address	to advertise, therefore	the hostname
	   is resolved to an IP	which is the advertised. This is NOT used for
	   listening and it is also overwritten	by afp listen.

       max connections = number	(G)
	   Sets	the maximum number of clients that can simultaneously connect
	   to the server (default is 200).

       server quantum =	number (G)
	   This	specifies the DSI server quantum. The default value is
	   0x100000 (1 MiB). The maximum value is 0xFFFFFFFFF, the minimum is
	   32000. If you specify a value that is out of	range, the default
	   value will be set. Do not change this value unless you're
	   absolutely sure, what you're	doing

       sleep time = number (G)
	   Keep	sleeping AFP sessions for number hours before disconnecting
	   clients in sleep mode. Default is 10	hours.

       tcprcvbuf = number (G)
	   Try to set TCP receive buffer using setsockopt(). Often OSes	impose
	   restrictions	on the applications ability to set this	value.

       tcpsndbuf = number (G)
	   Try to set TCP send buffer using setsockopt(). Often	OSes impose
	   restrictions	on the applications ability to set this	value.

       recvfile	= BOOLEAN (default: no)	(G)
	   Whether to use splice() on Linux for	receiving data.

       splice size = number (default: 64k) (G)
	   Maximum number of bytes spliced.

       use sendfile = BOOLEAN (default:	yes) (G)
	   Whether to use sendfile.  syscall for sending file data to clients.

       zeroconf	= BOOLEAN (default: yes) (G)
	   Whether to use automatic Zeroconf.  service registration if Avahi
	   or mDNSResponder were compiled in.

   Miscellaneous Options
       afp read	locks =	BOOLEAN	(default: no) (G)
	   Whether to apply locks to the byte region read in FPRead calls. The
	   AFP spec mandates this, but it's not	really in line with UNIX
	   semantics and is a performance hug.

       afpstats	= BOOLEAN (default: no)	(G)
	   Whether to provide AFP runtime statistics (connected	users, open
	   volumes) via	dbus.

       basedir regex = regex (H)
	   Regular expression which matches the	parent directory of the	user
	   homes. If basedir regex contains symlink, you must set the
	   canonicalized absolute path.	In the simple case this	is just	a path
	   ie basedir regex = /home

       chmod request = preserve	(default) | ignore | simple (G)/(V)
	   Advanced permission control that deals with ACLs.

	   o	ignore - UNIX chmod() requests are completely ignored, use
	       this option to allow the	parent directory's ACL inheritance
	       full control over new items.

	   o	preserve - preserve ZFS	ACEs for named users and groups	or
	       POSIX ACL group mask

	   o	simple - just to a chmod() as requested	without	any extra

       close vol = BOOLEAN (default: no) (G)
	   Whether to close volumes possibly opened by clients when they're
	   removed from	the configuration and the configuration	is reloaded.

       cnid mysql host = MySQL server address (G)
	   name	or address of a	MySQL server for use with the mysql CNID

       cnid mysql user = MySQL user (G)
	   MySQL user for authentication with the server.

       cnid mysql pw = password	(G)
	   Password for	MySQL server.

       cnid mysql db = database	name (G)
	   Name	of an existing database	for which the specified	user has full

       cnid server = ipaddress[:port] (G)/(V)
	   Specifies the IP address and	port of	a cnid_metad server, required
	   for CNID dbd	backend. Defaults to localhost:4700. The network
	   address may be specified either in dotted-decimal format for	IPv4
	   or in hexadecimal format for	IPv6.-

       dbus daemon = path (G)
	   Sets	the path to dbus-daemon	binary used by Spotlight feature. The
	   default value [/bin/dbus-daemon] is determined when building

       dircachesize = number (G)
	   Maximum possible entries in the directory cache. The	cache stores
	   directories and files. It is	used to	cache the full path to
	   directories and CNIDs which considerably speeds up directory

	   Default size	is 8192, maximum size is 131072. Given value is
	   rounded up to nearest power of 2. Each entry	takes about 100	bytes,
	   which is not	much, but remember that	every afpd child process for
	   every connected user	has its	cache.

       extmap file = path (G)
	   Sets	the path to the	file which defines file	extension type/creator
	   mappings. (default is @pkgconfdir@/extmap.conf).

       force xattr with	sticky bit = BOOLEAN (default: no) (G/V)
	   Writing metadata xattr on directories with the sticky bit set may
	   fail	even though we may have	write access to	a directory, because
	   if the sticky bit is	set only the owner is allowed to write xattrs.

	   By enabling this option Netatalk will write the metadata xattr as

       guest account = name (G)
	   Specifies the user that guests should use (default is "nobody").
	   The name should be quoted.

       home name = name	(H)
	   AFP user home volume	name. The default is $u's home.

       ignored attributes = all	| nowrite | nodelete | norename	(G)/(V)
	   Speficy a set of file and directory attributes that shall be
	   ignored by the server, all includes all the other options.

	   In OS X when	the Finder sets	a lock on a file/directory or you set
	   the BSD uchg	flag in	the Terminal, all three	attributes are used.
	   Thus	in order to ignore the Finder lock/BSD uchg flag, add set
	   ignored attributes =	all.

       login message = message (G)/(V)
	   Sets	a message to be	displayed when clients logon to	the server.
	   The message should be in unix charset and should be quoted.
	   Extended characters are allowed.

       mimic model = model (G)
	   Specifies the icon model that appears on clients. Defaults to off.
	   Note	that netatalk must support Zeroconf. Examples: RackMac (same
	   as Xserve), PowerBook, PowerMac, Macmini, iMac, MacBook,
	   MacBookPro, MacBookAir, MacPro, AppleTV1,1, AirPort.

       signature = <text> (G)
	   Specify a server signature. The maximum length is 16	characters.
	   This	option is useful for clustered environments, to	provide	fault
	   isolation etc. By default, afpd generate signature and saving it to
	   /var/netatalk/afp_signature.conf automatically (based on random
	   number). See	also

       solaris share reservations = BOOLEAN (default: yes) (G)
	   Use share reservations on Solaris. Solaris CIFS server uses this
	   too,	so this	makes a	lock coherent multi protocol server.

       sparql results limit = NUMBER (default: UNLIMITED) (G)
	   Impose a limit on the number	of results queried from	Tracker	via
	   SPARQL queries.

       spotlight = BOOLEAN (default: no) (G)/(V)
	   Whether to enable Spotlight searches. Note: once the	global option
	   is enabled, any volume that is not enabled won't be searchable at
	   all.	See also dbus daemon option.

       spotlight attributes = COMMA SEPARATED STRING (default: EMPTY) (G)
	   A list of attributes	that are allowed to be used in Spotlight
	   searches. By	default	all attributes can be searched,	passing	a
	   string limits attributes to elements	of the string. Example:

	       spotlight attributes = *,kMDItemTextContent

       spotlight expr =	BOOLEAN	(default: yes) (G)
	   Whether to allow the	use of logic expression	in searches.

       start dbus = BOOLEAN (default: yes) (G)
	   Whether to start a dbus instance for	use with Tracker.

       start tracker = BOOLEAN (default: yes) (G)
	   Whether to start Tracker with "tracker daemon -s". In case of old
	   Tracker, "tracker-control -s" is used instead.

       veto message = BOOLEAN (default:	no) (G)
	   Send	optional AFP messages for vetoed files.	Then whenever a	client
	   tries to access any file or directory with a	vetoed name, it	will
	   be sent an AFP message indicating the name and the directory.

       vol dbpath = path (G)/(V)
	   Sets	the database information to be stored in path. You have	to
	   specify a writable location,	even if	the volume is read only. The
	   default is /var/netatalk/CNID/$v/.

       vol dbnest = BOOLEAN (default: no) (G)
	   Setting this	option to true brings back Netatalk 2 behaviour	of
	   storing the CNID database in	a folder called	.AppleDB inside	the
	   volume root of each share.

       volnamelen = number (G)
	   Max length of UTF8-MAC volume name for Mac OS X. Note that Hangul
	   is especially sensitive to this.

	       73: limit of Mac	OS X 10.1
	       80: limit of Mac	OS X 10.4/10.5 (default)
	       255: limit of recent Mac	OS X

	   Mac OS 9 and	earlier	are not	influenced by this, because Maccharset
	   volume name is always limited to 27 bytes.

       vol preset = name (G)/(V)
	   Use section name as option preset for all volumes (when set in the
	   [Global] section) or	for one	volume (when set in that volume's

       zeroconf	name = name (G)
	   Specifies a human-readable name that	uniquely describes registered
	   services. The zeroconf name is advertised as	UTF-8, up to 63	octets
	   (bytes) in length. Defaults to hostname. Note that netatalk must
	   support Zeroconf.

   Logging Options
       log file	= logfile (G)
	   If not specified Netatalk logs to syslogs daemon facility.
	   Otherwise it	logs to	logfile.

       log level = type:level [type:level ...] (G), log	level =
       type:level,[type:level, ...] (G)
	   Specify that	any message of a loglevel up to	the given log level
	   should be logged.

	   By default afpd logs	to syslog with a default logging setup
	   equivalent to default:note

	   logtypes: default, afpdaemon, logger, uamsdaemon

	   loglevels: severe, error, warn, note, info, debug, debug6, debug7,
	   debug8, debug9, maxdebug

	       Both logtype and	loglevels are case insensitive.

   Filesystem Change Events (FCE.
       Netatalk	includes a nifty filesystem change event mechanism where afpd
       processes notify	interested listeners about certain filesystem event by
       UDP network datagrams.

       The following FCE events	are defined:

       o   file	modification (fmod)

       o   file	deletion (fdel)

       o   directory deletion (ddel)

       o   file	creation (fcre)

       o   directory creation (dcre)

       o   file	move or	rename (fmov)

       o   directory move or rename (dmov)

       o   login (login)

       o   logout (logout)

       fce listener = host[:port] (G)
	   Enables sending FCE events to the specified host, default port is
	   12250 if not	specified. Specifying multiple listeners is done by
	   having this option once for each of them.

       fce version = 1|2 (G)
	   FCE protocol	version, default is 1. You need	version	2 for the
	   fmov, dmov, login or	logout events.

       fce events = fmod,fdel,ddel,fcre,dcre,fmov,dmov,login,logout (G)
	   Specifies which FCE events are active, default is

       fce coalesce = all|delete|create	(G)
	   Coalesce FCE	events.

       fce holdfmod = seconds (G)
	   This	determines the time delay in seconds which is always waited if
	   another file	modification for the same file is done by a client
	   before sending an FCE file modification event (fmod). For example
	   saving a file in Photoshop would generate multiple events by	itself
	   because the application is opening, modifying and closing a file
	   multiple times for every "save". Default: 60	seconds.

       fce ignore names	= NAME[/NAME2/...] (G)
	   Slash delimited list	of filenames for which FCE events shall	not be
	   generated. Default: .DS_Store.

       fce notify script = PATH	(G)
	   Script which	will be	executed for every FCE event, see
	   contrib/shell_utils/	from the Netatalk sources for
	   an example script.

   Debug Parameters
       These options are useful	for debugging only.

       tickleval = number (G)
	   Sets	the tickle timeout interval (in	seconds). Defaults to 30.

       timeout = number	(G)
	   Specify the number of tickles to send before	timing out a
	   connection. The default is 4, therefore a connection	will timeout
	   after 2 minutes.

       client polling =	BOOLEAN	(default: no) (G)
	   With	this option enabled, afpd won't	advertise that it is capable
	   of server notifications, so that connected clients poll the server
	   every 10 seconds to detect changes in opened	server windows.	 Note:
	   Depending on	the number of simultaneously connected clients and the
	   network's speed, this can lead to a significant higher load on your

	   Do not use this option any longer as	present	Netatalk correctly
	   supports server notifications, allowing connected clients to	update
	   folder listings in case another client changed the contents.

   Options for ACL handling
       By default, the effective permission of the authenticated user are only
       mapped to the mentioned UARights	permission structure, not the UNIX
       mode. You can adjust this behaviour with	the configuration option map

       map acls	= none|rights|mode (G)

	       no mapping of ACLs

	       effective permissions are mapped	to UARights structure. This is
	       the default.

	       ACLs are	additionally mapped to the UNIX	mode of	the filesystem

       If you want to be able to display ACLs on the client, you must setup
       both client and server as part on a authentication domain (directory
       service,	eg LDAP, Open Directory, Active	Directory). The	reason is, in
       OS X ACLs are bound to UUIDs, not just uid's or gid's. Therefor
       Netatalk	must be	able to	map every filesystem uid and gid to a UUID so
       that it can return the server side ACLs which are bound to UNIX uid and
       gid mapped to OS	X UUIDs.

       Netatalk	can query a directory server using LDAP	queries. Either	the
       directory server	already	provides an UUID attribute for user and	groups
       (Active Directory, Open Directory) or you reuse an unused attribute (or
       add a new one) to you directory server (eg OpenLDAP).

       The following LDAP options must be configured for Netatalk:

       ldap auth method	= none|simple|sasl (G)
	   Authentication method: none | simple	| sasl

	       anonymous LDAP bind

	       simple LDAP bind

	       SASL. Not yet supported !

       ldap auth dn = dn (G)
	   Distinguished Name of the user for simple bind.

       ldap auth pw = password (G)
	   Password for	simple bind.

       ldap server = host (G)
	   Name	or IP address of your LDAP Server. This	is only	needed for
	   explicit ACL	support	in order to be able to query LDAP for UUIDs.

	   You can use afpldaptest(1) to syntactically check your config.

       ldap userbase = base dn (G)
	   DN of the user container in LDAP.

       ldap userscope =	scope (G)
	   Search scope	for user search: base |	one | sub

       ldap groupbase =	base dn	(G)
	   DN of the group container in	LDAP.

       ldap groupscope = scope (G)
	   Search scope	for group search: base | one | sub

       ldap uuid attr =	dn (G)
	   Name	of the LDAP attribute with the UUIDs.

	   Note: this is used both for users and groups.

       ldap name attr =	dn (G)
	   Name	of the LDAP attribute with the users short name.

       ldap group attr = dn (G)
	   Name	of the LDAP attribute with the groups short name.

       ldap uuid string	= STRING (G)
	   Format of the uuid string in	the directory. A series	of x and -,
	   where every x denotes a value 0-9a-f	and every - is a separator.

	   Default: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx

       ldap uuid encoding = string | ms-guid (default: string) (G)
	   Format of the UUID of the LDAP attribute, allows usage of the
	   binary objectGUID fields from Active	Directory. If left
	   unspecified,	string is the default, which passes through the	ASCII
	   UUID	returned by most other LDAP stores. If set to ms-guid, the
	   internal UUID representation	is converted to	and from the binary
	   format used in the objectGUID attribute found on objects in Active
	   Directory when interacting with the server.

	   See also the	options	ldap user filter and ldap group	filter.

	       UUID is a string, use with eg OpenDirectory.

	       Binary objectGUID from Active Directory

       ldap user filter	= STRING (default: unused) (G)
	   Optional LDAP filter	that matches user objects. This	is necessary
	   for Active Directory	environments where users and groups are	stored
	   in the same directory subtree.

	   Recommended setting for Active Directory: objectClass=user.

       ldap group filter = STRING (default: unused) (G)
	   Optional LDAP filter	that matches group objects. This is necessary
	   for Active Directory	environments where users and groups are	stored
	   in the same directory subtree.

	   Recommended setting for Active Directory: objectClass=group.

       The section name	defines	the volume name. No two	volumes	may have the
       same name. The volume name cannot contain the ':' character. The	volume
       name is mangled if it is	very long. Mac charset volume name is limited
       to 27 characters. UTF8-MAC volume name is limited to volnamelen

       path = PATH (V)
	   The path name must be a fully qualified path	name.

       appledouble = ea|v2 (V)
	   Specify the format of the metadata files, which are used for	saving
	   Mac resource	fork as	well. Earlier versions used AppleDouble	v2,
	   the new default format is ea.

       vol size	limit =	size in	MiB (V)
	   Useful for Time Machine: limits the reported	volume size, thus
	   preventing Time Machine from	using the whole	real disk space	for
	   backup. Example: "vol size limit = 1000" would limit	the reported
	   disk	space to 1 GB.	IMPORTANT: This	is an approximated calculation
	   taking into account the contents of Time Machine sparsebundle
	   images. Therefor you	MUST NOT use this volume to store other
	   content when	using this option, because it would NOT	be accounted.
	   The calculation works by reading the	band size from the Info.plist
	   XML file of the sparsebundle, reading the bands/ directory counting
	   the number of band files, and then multiplying one with the other.

       valid users = user @group (V)
	   The allow option allows the users and groups	that access a share to
	   be specified. Users and groups are specified, delimited by spaces
	   or commas. Groups are designated by a @ prefix. Names may be	quoted
	   in order to allow for spaces	in names. Example:

	       valid users = user "user	2" @group "@group 2"

       invalid users = users/groups (V)
	   The deny option specifies users and groups who are not allowed
	   access to the share.	It follows the same format as the "valid
	   users" option.

       hosts allow = IP	host address/IP	netmask	bits [ ... ] (V)
	   Only	listed hosts and networks are allowed, all others are
	   rejected. The network address may be	specified either in
	   dotted-decimal format for IPv4 or in	hexadecimal format for IPv6.

	   Example: hosts allow	= 2001:0db8:1234::/48

       hosts deny = IP host address/IP netmask bits [ ... ] (V)
	   Listed hosts	and nets are rejected, all others are allowed.

	   Example: hosts deny = 192.168.100/24 2001:db8::1428:57ab

       cnid scheme = backend (V)
	   set the CNID	backend	to be used for the volume, default is [dbd]
	   available schemes: [	dbd last tdb]

       ea = none|auto|sys|ad|samba (V)
	   Specify how Extended	Attributes.  are stored.  auto is the default.

	       Try sys (by setting an EA on the	shared directory itself),
	       fallback	to ad. Requires	writable volume	for performing test.
	       "read only = yes" overwrites auto with none. Use	explicit "ea =
	       sys|ad" for read-only volumes where appropriate.

	       Use filesystem Extended Attributes.

	       Use filesystem Extended Attributes, but append a	0 byte to each
	       xattr in	order to be compatible with Samba's vfs_streams_xattr.

	       Use files in .AppleDouble directories.

	       No Extended Attributes support.

       mac charset = CHARSET (V)
	   specifies the Mac client charset for	this Volume, e.g.  MAC_ROMAN,
	   MAC_CYRILLIC. If not	specified the global setting is	applied. This
	   setting is only required if you need	volumes, where the Mac charset
	   differs from	the one	globally set in	the [Global] section.

       casefold	= option (V)
	   The casefold	option handles,	if the case of filenames should	be
	   changed. The	available options are:

	   tolower - Lowercases	names in both directions.

	   toupper - Uppercases	names in both directions.

	   xlatelower -	Client sees lowercase, server sees uppercase.

	   xlateupper -	Client sees uppercase, server sees lowercase.

       password	= password (V)
	   This	option allows you to set a volume password, which can be a
	   maximum of 8	characters long	(using ASCII strongly recommended at
	   the time of this writing).

       file perm = mode	(V), directory perm = mode (V)
	   Add(or) with	the client requested permissions: file perm is for
	   files only, directory perm is for directories only. Don't use with
	   "unix priv =	no".

	   Example. Volume for a collaborative workgroup

	       file perm = 0660	directory perm =

       umask = mode (V)
	   set perm mask. Don't	use with "unix priv = no".

       preexec = command (V)
	   command to be run when the volume is	mounted

       postexec	= command (V)
	   command to be run when the volume is	closed

       root preexec = command (V)
	   command to be run as	root when the volume is	mounted

       root postexec = command (V)
	   command to be run as	root when the volume is	closed

       rolist =	users/groups (V)
	   Allows certain users	and groups to have read-only access to a
	   share. This follows the allow option	format.

       rwlist =	users/groups (V)
	   Allows certain users	and groups to have read/write access to	a
	   share. This follows the allow option	format.

       veto files = vetoed names (V)
	   hide	files and directories,where the	path matches one of the	'/'
	   delimited vetoed names. The veto string must	always be terminated
	   with	a '/', eg. "veto files = veto1/", "veto	files =	veto1/veto2/".

   Volume options
       Boolean volume options.

       acls = BOOLEAN (default:	yes) (V)
	   Whether to flag volumes as supporting ACLs. If ACL support is
	   compiled in,	this is	yes by default.

       case sensitive =	BOOLEAN	(default: yes) (V)
	   Whether to flag volumes as supporting case-sensitive	filenames. If
	   the filesystem is case-insensitive, set to no. However, it is not
	   fully verified.

	       In spite	of being case sensitive	as a matter of fact, netatalk
	       3.1.3 and earlier did not notify	kCaseSensitive flag to the
	       client. Starting	with 3.1.4, it is notified correctly by

       cnid dev	= BOOLEAN (default: yes) (V)
	   Whether to use the device number in the CNID	backends. Helps	when
	   the device number is	not constant across a reboot, eg cluster, ...

       convert appledouble = BOOLEAN (default: yes) (V)
	   Whether automatic conversion	from appledouble = v2 to appledouble =
	   ea is performed when	accessing filesystems from clients. This is
	   generally useful, but costs some performance. It's recommendable to
	   run dbd on volumes and do the conversion with that. Then this
	   option can be set to	no.

       delete veto files = BOOLEAN (default: no) (V)
	   This	option is used when Netatalk is	attempting to delete a
	   directory that contains one or more vetoed files or directories
	   (see	the veto files option).	If this	option is set to no (the
	   default) then if a directory	contains any non-vetoed	files or
	   directories then the	directory delete will fail. This is usually
	   what	you want.

	   If this option is set to yes, then Netatalk will attempt to
	   recursively delete any files	and directories	within the vetoed

       follow symlinks = BOOLEAN (default: no) (V)
	   The default setting is false	thus symlinks are not followed on the
	   server. This	is the same behaviour as OS X's	AFP server. Setting
	   the option to true causes afpd to follow symlinks on	the server.
	   symlinks may	point outside of the AFP volume, currently afpd
	   doesn't do any checks for "wide symlinks".

	       This option will	subtly break when the symlinks point across
	       filesystem boundaries.

       invisible dots =	BOOLEAN	(default: no) (V)
	   make	dot files invisible. WARNING: enabling this option will	lead
	   to unwanted sideeffects were	OS X applications when saving files to
	   a temporary file starting with a dot	first, then renaming the temp
	   file	to its final name, result in the saved file being invisible.
	   The only thing this option is useful	for is making files that start
	   with	a dot invisible	on Mac OS 9. It's completely useless on	Mac OS
	   X, as both in Finder	and in Terminal	files starting with a dot are
	   hidden anyway.

       network ids = BOOLEAN (default: yes) (V)
	   Whether the server support network ids. Setting this	to no will
	   result in the client	not using ACL AFP functions.

       preexec close = BOOLEAN (default: no) (V)
	   A non-zero return code from preexec close the volume	being
	   immediately,	preventing clients to mount/see	the volume in

       read only = BOOLEAN (default: no) (V)
	   Specifies the share as being	read only for all users. Overwrites ea
	   = auto with ea = none

       root preexec close= BOOLEAN (default: no) (V)
	   A non-zero return code from root_preexec closes the volume
	   immediately,	preventing clients to mount/see	the volume in

       search db = BOOLEAN (default: no) (V)
	   Use fast CNID database namesearch instead of	slow recursive
	   filesystem search. Relies on	a consistent CNID database, ie Samba
	   or local filesystem access lead to inaccurate or wrong results.
	   Works only for "dbd"	CNID db	volumes.

       stat vol	= BOOLEAN (default: yes) (V)
	   Whether to stat volume path when enumerating	volumes	list, useful
	   for automounting or volumes created by a preexec script.

       time machine = BOOLEAN (default:	no) (V)
	   Whether to enable Time Machine support for this volume.

       unix priv = BOOLEAN (default: yes) (V)
	   Whether to use AFP3 UNIX privileges.	This should be set for OS X
	   clients. See	also: file perm, directory perm	and umask.

       The AFP protocol	mostly refers to files and directories by ID and not
       by name.	Netatalk needs a way to	store these ID's in a persistent way,
       to achieve this several different CNID backends are available. The CNID
       Databases are by	default	located	in the
       /var/netatalk/CNID/(volumename)/.AppleDB/ directory.

	   "Concurrent database", backend is based on Oracle Berkley DB. With
	   this	backend	several	afpd daemons access the	CNID database
	   directly. Berkeley DB locking is used to synchronize	access,	if
	   more	than one afpd process is active	for a volume. The drawback is,
	   that	the crash of a single afpd process might corrupt the database.

	   Access to the CNID database is restricted to	the cnid_metad daemon
	   process.  afpd processes communicate	with the daemon	for database
	   reads and updates. If built with Berkeley DB	transactions the
	   probability for database corruption is practically zero, but
	   performance can be slower than with cdb

	   This	backend	is an exception, in terms of ID	persistency. ID's are
	   only	valid for the current session. This is basically what afpd did
	   in the 1.5 (and 1.6)	versions. This backend is still	available, as
	   it is useful	for e.g. sharing cdroms. Starting with Netatalk	3.0,
	   it becomes the read only mode automatically.

	   Warning: It is NOT recommended to use this backend for volumes
	   anymore, as afpd now	relies heavily on a persistent ID database.
	   Aliases will	likely not work	and filename mangling is not

       Even though ./configure --help might show that there are	other CNID
       backends	available, be warned those are likely broken or	mainly used
       for testing. Don't use them unless you know what	you're doing, they may
       be removed without further notice from future versions.

       With OS X Apple introduced the AFP3 protocol. One of the	most important
       changes was that	AFP3 uses unicode names	encoded	as UTF-8 decomposed.
       Previous	AFP/OS versions	used codepages,	like MacRoman,
       MacCentralEurope, etc.

       afpd needs a way	to preserve extended Macintosh characters, or
       characters illegal in unix filenames, when saving files on a unix
       filesystem. This	version	now uses UTF-8 as the default encoding for
       names. '/' will be converted to ':'.

       Earlier versions	used the the so	called CAP encoding. An	extended
       character (>0x7F) would be converted to a :xx sequence, e.g. the	Apple
       Logo (MacRoman: 0xF0) was saved as :f0. Some special characters would
       be converted as to :xx notation as well.	'/' would be encoded to	:2f, a
       leading dot '.' might be	encoded	as :2e.

       The vol charset option will allow you to	select another volume
       encoding.  afpd will accept any iconv(1)	provided charset. It is	highly
       recommended to stick to the default UTF-8.
