[Samba] Question about groups in ldap

[Tilo Lutz]

Hi

I have serveral questions about groups in ldap.

Is it possible to use different groups with the
same well known SID or is a well known SID only
allowed once?

Is it allowed to uses spaces in groupnames, e.g. "domain admins"?
Afaik groups with spaces are not posix conform.

In Samba-Developers-Guide.pdf included with samba 3.0 page 72f.
In the document well known groups have special names starting with
DOMAIN_. Can Windows clients recognize these names and translate them
into localized groupnames, like "user" or "power users" in english and
"Benutzer" and "Hauptbenutzer" in german?
