samba - Mar 2010 - problem with samba PDC and Windows 7 loading roaming profiles

Since years I have a Suse Samba PDC running with Win2000 and WinXP clients.
Now I tried to add 2 Win7 clients and I'm having a problem. Win7 don't 
load my
roaming profiles, Win7 always logged in to a domain user using a 
temporary profile.

First I upgrades to Samba 3.4.2 (Suse 11.2), than I set the registry 
entries according
Samba wiki: http://wiki.samba.org/index.php/Windows7
Now I was able to register the Win7 clients and I could login with a 
domain user but
the user always using a temporary profile. I tried this with different 
user -> same result.

I copied the domain profiles to <username>.V2 -> same result.
My domain profile looks like:

[nt-profile]
        comment = Client Profiles
        path = /BUERO/samba/nt-profile/%u
        read only = No
        create mask = 0600
        directory mask = 0700

drwxr-sr-x 30 admin    users  4096 2010-03-08 19:24 admin.V2


Following the samba log at login:

I found in the log an entry telling about nt-profile.v2. I didn't find 
any information about
that service (is it necessary or not). For testing I defined it in 
smb.conf but no success (maybe
I defined it wrong).

The WinXP clients are still working prefectly. Any help would be 
appreciated.
