samba - Dec 2007 - [3.2.0pre1] net ads join fails with NT_STATUS_NOLOGON_WORKSTATION_TRUST_ACCOUNT

Hi List,

i'm trying to join a Windows 2000 SP4 Domain (Native mode). I'm getting
the following error while joining:

# net ads join -U 'Administrator%password'
Using short domain name -- W2K
Could not connect to server dc.w2k.bitebene.org
Connection failed: NT_STATUS_NOLOGON_WORKSTATION_TRUST_ACCOUNT
Failed to verify membership in domain:
NT_STATUS_NOLOGON_WORKSTATION_TRUST_ACCOUNT!
Failed to join domain: No logon workstation trust account

my smb.conf:

[global]
realm = W2K.BITEBENE.ORG
netbios name = asg
security = ADS
idmap uid = 15000-20000
idmap gid = 15000-20000
winbind separator = +
winbind use default domain = yes
private dir = /etc/samba/private
use kerberos keytab = yes
client use spnego = yes
workgroup = W2K

(i'm only using winbindd)

The NT_STATUS_NOLOGON_WORKSTATION_TRUST_ACCOUNT above is probably
because we're using Machine Account credentials, but the Windows 2000
(With default security policy) denies logon with it.

In older Version net_rpc_join_ok used anonymous access, which won't work
on newer Windows Versions. (On this W2K it works).

So the only option left is using the supplied credentials during joining
- which works in all my cases (Win2003 SP2 / Win2000 SP4).

So i've changed the code back to the old one, but without anonymous flag:

As i'm not a samba expert, i don't know if this needs more changes, or
if there are some othere solutions.  Any thoughts?

Cheers,

Sven.
