процедуры обработки ошибок протокола LDAP (LDAP protocol error handling routines)
Имя (Name)
ldap_perror, ld_errno, ldap_result2error, ldap_errlist,
ldap_err2string - LDAP protocol error handling routines
Библиотека (Library)
OpenLDAP LDAP (libldap, -lldap)
Синопсис (Synopsis)
#include <ldap.h>
char *ldap_err2string( int err );
Описание (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).
Коды результатов протокола (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.
Коды ошибок API (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.
Устарело (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.
