I was thinking W2k to use AD-like authentication process (using PAC
extensions) when configured with Kerberos... I'll look a this.

Yep, but smbclient is a lot smarter than a whole W2k station ;)

Not so easy ... W2k is looking for an AD domain controller when setting up
with ksetup.exe and Samba/MIT KDC does not support PAC extensions. W2k Should
not be able to get accounting info (rid, primaryGroupID ...) well.
Anyway, i'll try this today but i am not sure about how you configured this.
