LDAP_ERROR(3)		   Library Functions Manual		 LDAP_ERROR(3)

NAME
       ldap_perror, ld_errno, ldap_result2error, ldap_errlist, ldap_err2string
       - LDAP protocol error handling routines

LIBRARY
       OpenLDAP	LDAP (libldap, -lldap)

SYNOPSIS
       #include	<ldap.h>

       char *ldap_err2string( int err );

DESCRIPTION
       The ldap_err2string() routine provides short description	of the various
       codes  returned	by routines in this library.  The returned string is a
       pointer to a static area	that should not	be modified.

       These codes are either negative,	indicating an API  error  code;	 posi-
       tive,  indicating  an  LDAP  resultCode	other than 'success' (0), or -
       zero, indicating	both successful	use of the API and the LDAP resultCode
       'success' (0).

       The   code   associated	with  an  LDAP	session	 is  accessible	 using
       ldap_get_option(3) and ldap_set_option(3) with the LDAP_OPT_RESULT_CODE
       option (previously called LDAP_OPT_ERROR_NUMBER).

PROTOCOL RESULT	CODES
       This  section  provides	a partial list of protocol codes recognized by
       the library.  As	LDAP is	extensible, additional values may be returned.
       A complete listing of registered	LDAP result codes can be obtained from
       the Internet Assigned Numbers Authority <http://www.iana.org>.

			   attribute.

       LDAP_CONSTRAINT_VIOLATION
			   An attribute	value  specified  violates  some  con-
			   straint  (e.g., a postalAddress has too many	lines,
			   or a	line that is too long).

       LDAP_TYPE_OR_VALUE_EXISTS
			   An attribute	 type  or  attribute  value  specified
			   already exists in the entry.

       LDAP_INVALID_SYNTAX An invalid attribute	value was specified.

       LDAP_NO_SUCH_OBJECT The	specified  object does not exist in The	Direc-
			   tory.

       LDAP_ALIAS_PROBLEM  An alias in The Directory points to	a  nonexistent
			   entry.

       LDAP_INVALID_DN_SYNTAX
			   A syntactically invalid DN was specified.

       LDAP_IS_LEAF	   The object specified	is a leaf.

       LDAP_ALIAS_DEREF_PROBLEM
			   A  problem  was  encountered	 when dereferencing an
			   alias.

       LDAP_INAPPROPRIATE_AUTH
			   Inappropriate authentication	was  specified	(e.g.,
			   LDAP_AUTH_SIMPLE  was  specified and	the entry does
			   not have a userPassword attribute).

       LDAP_INVALID_CREDENTIALS
			   Invalid credentials were presented (e.g., the wrong
			   password).

       LDAP_INSUFFICIENT_ACCESS
			   The	user  has  insufficient	 access	to perform the
			   operation.

       LDAP_BUSY	   The DSA is busy.

       LDAP_UNAVAILABLE	   The DSA is unavailable.

       LDAP_UNWILLING_TO_PERFORM
			   The DSA is unwilling	to perform the operation.

       LDAP_LOOP_DETECT	   A loop was detected.

       LDAP_NAMING_VIOLATION
			   A naming violation occurred.

       LDAP_OBJECT_CLASS_VIOLATION
			   An object class violation occurred (e.g., a	"must"
			   attribute was missing from the entry).

       LDAP_NOT_ALLOWED_ON_NONLEAF
			   The operation is not	allowed	on a nonleaf object.

       LDAP_NOT_ALLOWED_ON_RDN

API ERROR CODES
       This  section provides a	complete list of API error codes recognized by
       the library.   Note that	LDAP_SUCCESS indicates success of an API  call
       in  addition  to	 representing the return of the	LDAP 'success' result-
       Code.

       LDAP_SERVER_DOWN	   The LDAP library can't contact the LDAP server.

       LDAP_LOCAL_ERROR	   Some	local  error  occurred.	  This	is  usually  a
			   failed dynamic memory allocation.

       LDAP_ENCODING_ERROR An  error  was  encountered	encoding parameters to
			   send	to the LDAP server.

       LDAP_DECODING_ERROR An error was	encountered decoding a result from the
			   LDAP	server.

       LDAP_TIMEOUT	   A  timelimit	 was  exceeded	while  waiting	for  a
			   result.

       LDAP_AUTH_UNKNOWN   The authentication method specified to  ldap_bind()
			   is not known.

       LDAP_FILTER_ERROR   An  invalid	filter	was  supplied to ldap_search()
			   (e.g., unbalanced parentheses).

       LDAP_PARAM_ERROR	   An ldap routine was called with a bad parameter.

       LDAP_NO_MEMORY	   An memory  allocation  (e.g.,  malloc(3)  or	 other
			   dynamic  memory  allocator)	call failed in an ldap
			   library routine.

       LDAP_USER_CANCELED  Indicates the user cancelled	the operation.

       LDAP_CONNECT_ERROR  Indicates a connection problem.

       LDAP_NOT_SUPPORTED  Indicates the routine was called in	a  manner  not
			   supported by	the library.

       LDAP_CONTROL_NOT_FOUND
			   Indicates  the  control  provided is	unknown	to the
			   client library.

       LDAP_NO_RESULTS_RETURNED
			   Indicates no	results	returned.

       LDAP_MORE_RESULTS_TO_RETURN
			   Indicates more results could	be returned.

       LDAP_CLIENT_LOOP	   Indicates the library has detected a	 loop  in  its
			   processing.

       LDAP_REFERRAL_LIMIT_EXCEEDED
			   Indicates the referral limit	has been exceeded.

DEPRECATED
       Deprecated  interfaces  generally  remain  in  the  library.  The macro
       LDAP_DEPRECATED can be defined to a non-zero value (e.g., -DLDAP_DEPRE-
       CATED=1)	 when compiling	program	designed to use	deprecated interfaces.
       It is recommended that developers writing new programs, or updating old
       programs,  avoid	 use  of  deprecated  interfaces.   Over  time,	 it is
       expected	that documentation (and, eventually, support)  for  deprecated
       interfaces to be	eliminated.
