| Subject: [Samba] ACLs on client Samba machines with Samba PDC.
| I've got a Samba box (2.2.5a) as a member of a Samba domain. Both the PDC
| and client are running 2.4.18 with XFS and ACLs compiled in. Problem: on
| the client, I can -NOT- modify the ACLs for files from Windows. (Note
| that I can modify the stock Unix permissions, but not the extended
| users/permissions that ACL support offers.) If I try, they just vanish
| when I click "OK". However, if I remove the client from the domain, and
| set it up by itself with "security = user", it works fine.
I've been banging my head against this one for a while, since I was
trying to test ACLs on my member server (my desktop) before putting
2.2.5 on our production server. As it turns out, they work fine on the
production server, but not on my desktop member server ...
It turns out that on member servers, you can apply ACLs using the
"machine domain" (but for some reason, I only get groups, and not users
here?), but not the domain it is a member of.
You will probably notice that the permissions visible in the security
properties box list the users/groups on the "machine domain" instead of
the domain (in my case, BGMILNE-MDK83\bgmilne instead of CAE\bgmilne).
In the logs you will see that when you try and add ACLs with users from
the domain, samba fails to map the SID+RID from the domain to a uid.
This may require winbind-type functionality, or it may just be a bug
(and one worth fixing soon!).
| Am I doing something dumb, or is this an oversight/glitch/bug?
Seems like a bug, but I'm not sure it can work without winbind (and thus
a Windows DC) or with 2.2. Hopefully it works in HEAD, and hopefully 3.0
will be out soon.
Just FYI, I am running 2.2.5 with LDAP on the DC, and 2.2.5 without LDAP
on the member server. I hope ACLs work on an LDAP BDC, since we'll be
putting one in next week ...
