samba - Jun 2005 - Establish trust with Win 2003 - ACCESS DENIED

Hi,

I have a problem establishing a interdomain trust to Win2003 SP1 where the 
Windows domain is the trusted domain.
The other direction, the samba domain is trusted by the windows domain, 
works without problem.

When I try to establish the trust from the samba side, I get the following 
error:

# net rpc trustdom establish T18
Could not connect to server JPTEST121
[2005/06/22 11:41:35, 0, effective(0, 0), real(0, 0)] 
rpc_client/cli_pipe.c:cli_nt_session_open(1451)
  cli_nt_session_open: cli_nt_create failed on pipe \wkssvc to machine 
JPTEST121.  Error was NT_STATUS_ACCESS_DENIED
[2005/06/22 11:41:35, 0, effective(0, 0), real(0, 0)] 
utils/net_rpc.c:rpc_trustdom_establish(4672)
  Couldn't not initialise wkssvc pipe

I think, my configuration is OK - so for me this looks like a bug.

I've seen in the release notes for 3.0.12 that there was a bug, which 
should have been fixed in that release. 
But I use 3.0.14a.

Can anybody confirm, that this kind of trust does really work ?
Has anyone a working interdomain trust where Samba trusts a Windows 2003 
AD domain ?

Would be nice, if somebody could give me a hint. 

Thx in advance,
