Description William Brown 2012-12-17 00:14:22 UTC

Description of problem:
realmd with active directory, should support "permitting" logins based on group membership. For example

realm permit "Domain Admins"

Running this at the moment, realmd puts the option into SSSD

simple_allow_users = domain admins

Perhaps this is indicative of a limitation of SSSD, but it does impair realmd signifigantly.

Workaround:

For the momemt, winbind supports group based logins via the pam stack. IE require_membership_of=[SID or NAME] See also http://www.samba.org/samba/docs/man/manpages-3/pam_winbind.conf.5.html

Comment 1 Dmitri Pal 2012-12-17 03:29:00 UTC

I guess this is the limitation of the realmd. SSSD supports groups in the simple access provider as well as users. Please see all the man pages for sssd-simple. What happens above is that "Domain Admins" is treated as a user.

May be realmd should support another argument?

realm permit user "foo"
realm permit group "Domain Admins"

Yes it probably should. Or we should resolve the user/group on the fly and add it to the appropriate sssd-simple list.

Comment 3 William Brown 2012-12-18 00:41:08 UTC

Don't resolve the group on the fly. What if I have a user and group with the same name, but mean different things?

The "realm permit [user|group]" syntax is probably the better option, as it is explicit to the user what their action will result in.

Comment 4 Stef Walter 2012-12-18 09:00:46 UTC

Good point. I'm also not super happy with 'permit' 'deny' as it's not clear that they refer to logins. Will try to come up with a syntax that fixes both problems...

Is there anything new about group logins?
This is prefefred feature for low system administration footprint in large domain environments.
