smbpasswd fails when changing user passwords

[Marco.Schwarz at freudenberg.de]

Hello all,

I have yet another problem with my Samba 2.0.3 server:

When I try to change a users password either through SWAT or when logged in,
I get the following error message when trying to change the password:

---
machine 127.0.0.1 rejected the session setup. Error was: ERRSRV - ERRbadpw
(Bad password - name/password pair in a Tree Connect or Session Setup are
invalid.).
Failed to change password for xyz.
---

I can change the passwords for everybody when I'm the root user, but my
users are not able to change their passwords due to this error message.

Anybody got any ideas ?

Thanks

Marco.
