Hi, > The kdc(s) is(are) defined in /etc/krb5.conf in the [realms] section. > Could you post your /etc/krb5.conf? After my signature. I also join my current smb.conf > Do you know which machines in your active directory setup are the domain > controllers? These machines will be the KDCs. Yes. Its FQDN is srv-dte.dte.ua.pt and the domain name is DTE. Its IP is 192.137.84.81 It's a Windows 2000 Server with Active Directory. I remember my data: My domain is dte.ua.pt; whatever xxx.dte.ua.pt means xxx is, therefore, the name of the machine. 1 - The domain server as described above; 2 - I'm trying to join a Linux Samba server to the DTE domain, i. e., to the Windows 2000 Server. 3 - This Linux server FQDN is tux.dte.ua.pt and its IP is 193.137.84.84 Thank you.
