Hi Megas,

Maybe we should try the sysvol sync feature again. 

But this time on a different location. 
I'll update the wiki part on this. 

Basically what I'm think is like below. 

1. Create minimal 2 GPO on each DC with different name. 
2. Copy the whole sysvol to sysvol2 including all ACL and xattr
3. Check their ACL to take reference. Including the directory. Using getfacl 
4. Run rsync and unison on sysvol2 and check the result of both sides. 
5. Both of the ACL should be same.

Hope to see where are the problem is.

I couldn't find anything related to xattr. A global search with "rgrep -r -i xattr ." didn't output anything :( That's suspicious that unison cannot handle extended attributes. Good point Chan, maybe here's the culprit? I am not a pro, but maybe someone else can tell us more about unison and xattr support. The mailing list of unison here (https://groups.yahoo.com/neo/groups/unison-users/search/messages?query=xattr) didn't help either to find a suitable answer.
