So, I spent quite some time researching it all a bit more in depth but I 
get stuck at the same point, although I at least seem to have a better 
understanding of how things should be now.

So, my smb.conf on the member server looks exactly like the one in the 
wiki, except that I also added ACL support as suggested on the wiki page 
"Shares with Windows ACLs". My filesystem is XFS and has ACL built-in.

I do get proper results for wbinfo -u and wbinfo -g, but the id and 
getent commands just won't work. I'm trying it on users and groups that 
have a uidNumber or gidNumber defined, respectively.

This is how my nsswitch.conf looks like:

passwd: compat winbind
group: compat winbind
hosts:compat dns
networks: compat dns

My Samba came from a package but I verified that libnss_winbind.so.2 is 
properly linked.

smbd, nmbd and winbindd are properly started with no errors in the logs, 
I'm joined to the AD, I can browse the member server from my windows 
machine being logged in as Administrator. But I still can't seem to 
change ACLs on any objects in the share from within Windows, I'm getting 
error messages "Error when applying security" (I'm translating freely 
from German).

Do you have any idea what's going wrong here?
