If Authentication Fails
Solution

authentication mode.
To allow blank passwords,
contact your service
representative.
2. In simple authentication
mode, the DN of the login user
name is obtained in the user
account.
Authentication fails if the DN
cannot be obtained.
Make sure there are no errors
in the server name, login user
name/password, or
information entered for the
search filter.
