ldap_result2error(3) -- Linux man page

 

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 );

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 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_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

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 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_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.

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

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.
