[Samba] profile permissions

[Michelangelo Rezzonico]

I have a working samba-pdc installation with version 3.0.28
The "profile" permissions in 3.0.28 (and all the files in this directory)
are as follow:
drwx--x--x  2 user1 ntuser 4096 Aug 22 12:36 profile

I am installing a new server with samba version 3.6.3
The "profile" permissions in 3.6.3 (and all the files in this directory)
are as follow:
drwx--x--x+  2 user1 ntuser 4096 Aug 22 12:36 profile

The difference is the "+" sign that indicate acl permissions.
How can I correctly migrate the profile from 3.0.28 to 3.6.3 in order that
the permission are set correctly ?

Thanks a lot for any help.
