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

char *ldap_err2string( int err );

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

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

DESCRIPTION
These routines provide interpretation of the various error codes returned by the LDAP pro-
tocol and LDAP library routines or associated with an LDAP session. The error code asso-
ciated 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).

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.

ERRORS
The possible values for an ldap error code are:

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 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.

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.
