LOGIN.ACCESS(5)		    BSD	File Formats Manual	       LOGIN.ACCESS(5)

NAME
     login.access -- login access control table

DESCRIPTION
     The login.access file specifies (user, host) combinations and/or (user,
     tty) combinations for which a login will be either	accepted or refused.

     When someone logs in, the login.access is scanned for the first entry
     that matches the (user, host) combination,	or, in case of non-networked
     logins, the first entry that matches the (user, tty) combination.	The
     permissions field of that table entry determines whether the login	will
     be	accepted or refused.

     Each line of the login access control table has three fields separated by
     a `:' character: permission:users:origins

     The first field should be a "+" (access granted) or "-" (access denied)
     character.

     The second	field should be	a list of one or more login names, group
     names, or ALL (always matches).

     The third field should be a list of one or	more tty names (for non-net-
     worked logins), host names, domain	names (begin with "."),	host ad-
     dresses, internet network numbers (end with "."), ALL (always matches) or
     LOCAL (matches any	string that does not contain a "." character).	If you
     run NIS you can use @netgroupname in host or user patterns.

     The EXCEPT	operator makes it possible to write very compact rules.

     The group file is searched	only when a name does not match	that of	the
     logged-in user.  Only groups are matched in which users are explicitly
     listed: the program does not look at a user's primary group id value.
