[Samba] problem configuring smbd for domain authentication

[rohitm at engr.uconn.edu]

One other thing I noticed, if I set "security = server" it works fine (Windows clients can authenticate
of Windows DC and access samba resources), but I still cannot get it to work with "security = domain"

Has anyone had success with security = domain?  I would love to read your configuration files.

Thanks

Rohit
