samba - May 2012 - Windows 7 often creates new user profiles

Hi,

we're using Samba 3.5.6 (Debian). 

Windows 7 clients often create new roaming profiles for existing users for no
identifiable reason. Windows XP isn't affected.

Is this a known problem?

I have never ever had that happen in the 2+ years I had windows 7
machines on my samba based domain.

Some reasons for this behavior I googled:

1. insufficient permissions for profile-folder
2. "trust relationship between this workstation and the primary domain
failed." --> dis-join and rejoin the workstation
3. .bak is appended in registry at HKEY_LOCAL_MACHINE\Software\Microsoft
\Windows NT\CurrentVersion\ProfileList. Remove the other SIDs and the
".bak" extension.
4. do not use roaming profiles. (But there are other problems with
folder redirection [1].)
