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

OpenLDAP LDAP (libldap, -lldap)

#include <ldap.h>

char *ldap_err2string( int err );

void ldap_perror( LDAP *ld, const char *s )

int ldap_result2error( LDAP *ld, LDAPMessage *res, int freeit )

These routines provide interpretation of the various error codes returned by the LDAP protocol and LDAP library routines or associated with an LDAP session. The error code associated with an LDAP session is accessible using ldap_get_option(3) and ldap_set_option(3) with the LDAP_OPT_ERROR_NUMBER option.

The ldap_result2error() routine takes res, a result as produced by ldap_result(3) or ldap_search_s(3), and returns the corresponding error code. Possible error codes are listed below. If the freeit parameter is non zero it indicates that the res parameter should be freed by a call to ldap_msgfree(3) after the error code has been extracted. The ld_errno field in ld is set and returned.

The returned value can be passed to ldap_err2string() to get a text description of the message. The string returned from ldap_err2string() is a pointer to a static area that should not be modified.

The ldap_perror() routine can be called to print an indication of the error on standard error, similar to the way perror(3) works.

A compare operation returned true.

LDAP_STRONG_AUTH_NOT_SUPPORTED

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 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 Directory.

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.

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.

Object class modifications are not allowed.

LDAP_OTHER

An unknown error occurred.

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

LDAP_PARAM_ERROR

LDAP_NO_MEMORY

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