[Samba] Failing to store a SAM_ACCOUNT for [machine$] without a primary group RID

[Louis-David Mitterrand]

Hello,

After a clean install of 2.999+3.0.alpha23 on Debian, I try to add
machines to the domain without success; the smb.log displays this
message:

tdb_update_sam: Failing to store a SAM_ACCOUNT for [cythera$] without a primar
y group RID

I googled for this error with no result.

Thanks in advance for your help,
