[Samba] Vista joinDomain gdwError = 0x32

[Mario Gzuk]

Hi,
I am trying to join MS Vista to a samba (3.0.23) Domain. If I join the
domain manually all works fine, but when I try the unattended method I
got the following errors:

2008-03-04 02:58:32, Error                        [unattendedjoin.exe]
Unattended Join: NetJoinDomain failed error code is [50]
2008-03-04 02:58:32, Error                        [unattendedjoin.exe]
Unattended Join: Unable to join; gdwError = 0x32

I am searching the samba logs and the Internet, but there is no
description of this error (also not on microsoft.com). Maybe someone of
the samba experts know this error code? 
Let me know if you need more information.

Thank you for any hint.

greetings mario
