LDAP Server login problems with new Domain Controllers Windows 2016

Hi @ All,

we have new domain controllers with Windows Server 2016 and my colleague had set up the LDAP Connection to the new Server a few days after we installead the new domain controllers.

Now, the new domain controllers work for a few month and we shut down an old domaincontroller which has no entry anymore in the nextcloud, and no domainuser is able to log on.

The LDAP konfiguration is OK and you can test if a user is able to log on and it tells me.everything is ok. But its not working, no domain user is able to log on.
Only non-domainuser are able to log on.
Error message from the nextcloud protocoll
[user_ldap] Warning: Configuration Error (prefix s01): No LDAP Host given!

Where I’m able to see the real entry for the domaincontroller?
