ldap_errlist

       - 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;  posi-
       tive,  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_STRONG_AUTH_NOT_SUPPORTED
                           The LDAP server does not support strong authentica-
                           tion.

                           attribute.

       LDAP_CONSTRAINT_VIOLATION

                           straint  (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_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.

                           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' result-
       Code.



       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.

       Deprecated  interfaces  generally  remain  in  the  library.  The macro
       LDAP_DEPRECATED can be defined to a non-zero value (e.g., -DLDAP_DEPRE-
       CATED=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.
