samba - Nov 2009 - Problem with netbios aliases and security 'domain'

Hi!

I have the problem that a host can not with the 'netbios name' and the 
'alias' in a domain.
Under samba 2.x it can be done without any problem.

My samba version is: 3.2.7

Netbios name: u10
Netbios aliases: u2
Host has only one IP. Security is 'domain'.


When I type: # net rpc join MEMBER -U Administrator -n u10
I can join the domain. Access to u10 is successful.


When I type: # net rpc join MEMBER -U Administrator -n u2
I can join the domain. Access to u2 is successful. But I can not connect 
to u10 anymore.

Client:
"The trust relationship between this workstation and the primary domain
failed."

Server-Log:
[2009/11/02 10:24:09,  2] auth/auth.c:check_ntlm_password(318)
   check_ntlm_password:  Authentication for user [user1] -> [user1] 
FAILED with error NT_STATUS_TRUSTED_RELATIONSHIP_FAILURE


Any ideas or suggestions?




Thanks in advance!
