I have now disjoined this box from the domain and stopped winbind. As I assumed, the msktutil-utility still does not work (same error: can't contact ldap-server). The server is accessible with port 389/636. Within a tcpdump, I see, that there is encrypted traffic from squid-proxy to the domain-controller on port 389 (instead of 636). Could the problem be a missing library? Did someone run this tool successfully on sles11? 2010/6/29 Henrik Nordström <henrik@xxxxxxxxxxxxxxxxxxx>: > tis 2010-06-29 klockan 07:39 +0200 skrev Tom Tux: > >> The computer-account already exists in the ad (joined with "net ads join"). > > Adding principals to a Samba maintained computer account is a little > tricky.
