LDAP_ERROR(3)									    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;	positive,  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>.

       LDAP_SUCCESS	   The request was successful.

       LDAP_PROTOCOL_ERROR A protocol violation was detected.

       LDAP_TIMELIMIT_EXCEEDED
			   An LDAP time limit was exceeded.

       LDAP_SIZELIMIT_EXCEEDED
			   An LDAP size limit was exceeded.

       LDAP_COMPARE_FALSE  A compare operation returned false.

       LDAP_COMPARE_TRUE   A compare operation returned true.

       LDAP_STRONG_AUTH_NOT_SUPPORTED
			   The LDAP server does not support strong authentication.

       LDAP_STRONG_AUTH_REQUIRED
			   Strong authentication is required for the operation.

       LDAP_PARTIAL_RESULTS
			   Partial results only returned.

       LDAP_NO_SUCH_ATTRIBUTE
			   The attribute type specified does not exist in the entry.

       LDAP_UNDEFINED_TYPE The attribute type specified is invalid.

       LDAP_INAPPROPRIATE_MATCHING
			   Filter type not supported for the specified attribute.

       LDAP_CONSTRAINT_VIOLATION
			   An attribute value specified violates some constraint (e.g., a postal-
			   Address 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 Directory.

       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 miss-
			   ing from the entry).

       LDAP_NOT_ALLOWED_ON_NONLEAF
			   The operation is not allowed on a nonleaf object.

       LDAP_NOT_ALLOWED_ON_RDN
			   The operation is not allowed on an RDN.

       LDAP_ALREADY_EXISTS The entry already exists.

       LDAP_NO_OBJECT_CLASS_MODS
			   Object class modifications are not allowed.

       LDAP_OTHER	   An unknown error occurred.

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' resultCode.

       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  alloca-
			   tor) 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_DEPRECATED=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.
