I'm trying to authenticate Active Directory's users into a Linux workstation using samba.
Using SADMS I managed almost everything. But, when I try a wbinfo -t, I receive a message saying that RPC call failed, error 0x0, saying that it is unable to resolve the secret.

The W2k network uses NTLM/NTLMV2 cryptography, and I believe that maybe that is causing the problem (also because SADMS tries to authenticate in plain text).
Is there something I can do about it?
