[Samba] [samba] AD, add computers delegation

[mathias dufresne]

Hi,

Following that link https://support.microsoft.com/en-us/kb/932455 we
created a delegation to permit some group to add computers into AD.
That works except if some computer with same name was already added (even
if this computer with same name was previously cleanly removed from AD).

Anyone who has idea what we missed?

Cheers,

M.
