LDAP Error Codes

The LDAPResult is the construct used in this protocol to return success or failure indications from servers to clients. In response to various requests, servers will return responses containing fields of type LDAPResult to indicate the final status of a protocol operation request. The contents of the table below are from RFC 2251.

All the result codes with the exception of success, compareFalse and compareTrue are to be treated as meaning the operation could not be completed in its entirety. If a client receives a result code which is not listed in the table, it is to be treated as an unknown error condition.
