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_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.

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’ 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 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_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.

Opportunity

Personal Opportunity - Free software gives you access to billions of dollars of software at no cost. Use this software for your business, personal use or to develop a profitable skill. Access to source code provides access to a level of capabilities/information that companies protect though copyrights. Open source is a core component of the Internet and it is available to you. Leverage the billions of dollars in resources and capabilities to build a career, establish a business or change the world. The potential is endless for those who understand the opportunity.

Business Opportunity - Goldman Sachs, IBM and countless large corporations are leveraging open source to reduce costs, develop products and increase their bottom lines. Learn what these companies know about open source and how open source can give you the advantage.

Free Software

Free Software provides computer programs and capabilities at no cost but more importantly, it provides the freedom to run, edit, contribute to, and share the software. The importance of free software is a matter of access, not price. Software at no cost is a benefit but ownership rights to the software and source code is far more significant.

Free Office Software - The Libre Office suite provides top desktop productivity tools for free. This includes, a word processor, spreadsheet, presentation engine, drawing and flowcharting, database and math applications. Libre Office is available for Linux or Windows.

Free Books

The Free Books Library is a collection of thousands of the most popular public domain books in an online readable format. The collection includes great classical literature and more recent works where the U.S. copyright has expired. These books are yours to read and use without restrictions.

Source Code - Want to change a program or know how it works? Open Source provides the source code for its programs so that anyone can use, modify or learn how to write those programs themselves. Visit the GNU source code repositories to download the source.

Education

Study at Harvard, Stanford or MIT - Open edX provides free online courses from Harvard, MIT, Columbia, UC Berkeley and other top Universities. Hundreds of courses for almost all major subjects and course levels. Open edx also offers some paid courses and selected certifications.

Linux Manual Pages - A man or manual page is a form of software documentation found on Linux/Unix operating systems. Topics covered include computer programs (including library and system calls), formal standards and conventions, and even abstract concepts.
