(LDAP) authentication server does not work.
The Lightweight Directory Access Protocol (LDAP) authentication server does not work. This server acts as the Active Directory domain controller as well as a global catalog and it also populates the accounts cache. I did a test connection which is successful on “Start TLS” and on “encrypted.” Is it possible to use LDAP without running into any problem? It does not require any authentication but whenever I enter information in the base DN, I get the following error messages: ‘Filter error or invalid base DN.’ If I delete the base DN, it is possible to save the information.
I know my base DN is right because I have verified it many times.
What could be wrong here?
