I would interpret the message as if no connection to the LDAP server can be established and/or a LDAP query error appeared?!

First my LDAP is working fine but i have some problem with slow login and then i try to change some LDAP configure to the wrong parameter then i got Internal Server Error.

Can you revert the change so that it is working again? It might be a good idea to post the working and not working LDAP configuration so that other users can give you a hint what need to be changed.

Yes i want to go change back but when i go to setting for rollback configuration is show
