[Samba] Windows 7/Vista problem with offline files synchronization - samba 3.5.4 domain controller

[Jarosław Darnowski]

While using SAMBA 3.5.4 as a primary domain controller for Windows 
Workstations I have problems with offline files synchronization.

While using Windows XP everything works great, there is still no 
problems with machines with XP.
Problems started with Vista Business, there is a lot of synchronization 
conflicts. Windows 7 also have problems with proper offline files 
synchronization. Most synchro errors states "The process cannot access 
the file because it is being used by another process" or some other 
strange synchro conflicts.

Here is my output of smb.conf and smb-homes.conf files.

Anyone with working synchronization with Vista & Windows 7 please help, 
it's very important to me to get it to work.
Please examine this configuration and try to discover witch specific 
Win7/Vista options are missed or misconfigured.
