Hi,

I was experimenting different scenarios:

1. Provision Win200x join Samba4 remove Win200x
2. Provision Samba4
3. Upgrade from Samba3

I have tested the posix attributes only in the first case yet :-( .
However I do plan to test case 3 in the next few (max 3-4 month) once I 
can be sure that other parts of our infrastructure (currently Heimdal 
KDC and OpenLDAP based) would work on a Samba4 architecture.

Cheers
