But I’m using the same settings for the Checkmk user setup /authentication

same server, same bind DN

Any ideas to get the check_ldap working ?

pushing this, as a new Windows DC will not take unsecured connections.

Message from ldapsearch on the command line :

ldap_bind: Strong(er) authentication required (8)
        additional info: 00002028: LdapErr: DSID-0C090347, comment: The server requires binds to turn on integrity checking if SSL\TLS are not already active on the connection, data 0, v65f4

apparently this was a problem on the DC side, some setting was changed from the Admin, it is working now…
