Greetings, I am following Tournier's Howto to configure Samb 3.x as domain controller. I use "net rpc getsid -S <pdc-name> -W <domain name>" to obtain the domain SID and configure smbldap-tools and created the backend database. (The SID is also saved on secrets.db on local machine) I joint this server to the domain successfully using, "net rpc join -Uadministrator%password" The srvmgr.exe can see it joined the domain as a BDC. But when I try to synchronize the domain controllers using "net rpc vampire -Uadministrator&password" It faied with "Can not get CRED" or something like it. Waht did I do wrong?
