I have a problem on a slave server. For some reason it tries several connections to my ldap server until the ldap server crashes. I don't know how to identify what this possible service would be. I configured debian to connect in ldap so I can use ssh only

ISPConfig does not use Ldap, and it does not connect to a Ldap system. So you must have installed and configured something else on your system that does these connections.
