NAME
ldap_perror, ld_errno, ldap_result2error, ldap_errlist, ldap_err2string
- LDAP protocol error handling routines
SYNOPSIS
#include <ldap.h>
struct ldaperror {
int e_code;
char *e_reason;
};
struct ldaperror ldap_errlist[];
char *ldap_err2string(err)
int err;
void ldap_perror(ld, s)
LDAP *ld;
char *s;
int ldap_result2error(ld, res, freeit)
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, and assigned
to the ld_errno field in the ld structure.
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() or looked up in
ldap_errlist[] 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 last element in the ldap_errlist[] array
is signaled by an error code of -1.
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 authentica-
tion.
LDAP_STRONG_AUTH_REQUIRED
Strong authentication is required for the opera-
tion.
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 con-
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_INVALID_SYNTAX An invalid attribute value was specified.
LDAP_NO_SUCH_OBJECT The specified object does not exist in The Direc-
tory.
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.
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.
