Hi, One simple question. Is it possible with the new 3.0 to use samba as a Backup Domain controller (to authenticate nt users) for windowsNT4 ? Problem is that i have win on one side and linux on another side with leased lines between them. If samba can't be used as backup domain controller then the windows users on that side can't logon to there maps on that server when the leased line is down. I know about Winbindd, but if the leased line is down, winbindd is not valueable because winbindd gets its authentication from the NT4 PDC. GreetZ! Ph.
