[Samba] Samba 2.2.3a and password expiration?

[Peter Peltonen]

One of my users complained that his Win2kSP2 complains that his password
Is going to expire in 8 days.

A while ago we changed from Win2k domain to a Samba 2.2.3a controlled domain.

How do I disable the password expiration? I read the man pages and searched
Google but couldn't find any hints about the issue. It almos seems like this
expiration thing should not be happening at all...?

Peter
