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; 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>.
LDAP_SUCCESS The request was successful.
LDAP_OPERATIONS_ERROR
An operations error occurred.
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 authentica-
tion.
LDAP_STRONG_AUTH_REQUIRED
Strong authentication is required for the opera-
tion.
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 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
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' 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.
