I had installed 4 samba servers on a XEN hostsystem, to work as an ADS member server and use the kerberos for authentification. The local AD login on this virtual machines working very well. The Problem is more to bind the usershare with the single sign on, only on one v-machine the usershare is reachable directly, i tested also on a standalone server and it works, on the other three v-machines i get an Password prompt where i can authentifacte like "\\ad-controler\user" and it works. the config-files all the same. If i try a binding via the ip adresses like //192.168.1.x/homes it works also on the other v-machines, what is wrong ?
