[Samba] Does Samba/Winbind not follow nested groups in AD?!?

You are correct--I don't have windbind nested groups = yes set in my 
smb.conf. Yes, default 3.0.22. I followed the Ubuntu configuration 
instructions to the letter found in the Ubuntu forums that I've posted 
before with only the changes you've seen in my smb.conf. Here is the 
link to the forum post:


If you have a machine you can throw together as a test machine, fire it 
up as a stock install and follow these instructions to the letter (if 
you didn't on your production box) and see if you have any success.

Here's where the rubber meets the road. If your test machine correctly 
nests permissions, then there is something wrong with your production 
config. If it doesn't, then you have something going on in Active Directory.

One more thing--I'm using POSIX ACLs for permissions. Are you?
