[Samba] mapping well known groups problem (net groupmap)

[Piotr Legiecki]

Hi

I have samba 3.0.14a (debian/stable) and wonder where the problem is 
that running this command:

# net groupmap add ntgroup="Domain Admins" unixgroup=ntadmins rid=512
type=d
gives:
adding entry for group Domain Admins failed!

but (note changed rid)

# net groupmap add ntgroup="Domain Admins" unixgroup=ntadmins rid=1000
type=d
works fine.

Hm, winbind is not working, but I suppose it is not needed here.

So what is the problem with mapping?

Regards
