[Samba] Client accessing Samba doesn't authenticate against Active Directory
When a Windows client attempts to browse shares on a Samba 3.0 server authenticating against a Windows 2003 Active Directory domain, it requests credentials. Typing in user name and password fails. Basically, I can't see even see the shares. If I give username/password for a user in smbpasswd, then I can browse the Samba server.
