[Samba] Users can't change their passwords

[Mario Gamito]

Hi,

I have a smoothly running Samba PDC.
Just one thing that isn't working: when users try to change their
password in their windows 2000 machines, they get an error saying: "The
domain NETUAL is not available", but it is !!!
I even set 777 permissions on /etc/shadow (shame on me) just to test,
but nothing.

Curious thing is that i'm running a RH package 3.0.2

If i compile 3.0.4, they can change their passwors.

Any help would be appreciated.

Warm Regards,
Mário Gamito
