[Samba] Logon time restrictions?

[Anders Norrbring]

Hiya all!

I've browsed to lots of doc. Files, but I can't find a good answer.  Is it
possible to set logon time restrictions to users when Samba operates as a
PDC, controlling Windows XP Pro clients?

We're in the need to have different time restrictions based on user groups
as well as individual users.

Currently we run Samba v2.2.5, but will upgrade if needed.
