[Samba] Odd Samba/btrfs AD member server problem

[Moby]

openSUSE 13.2 machine with btrfs for /
Running samba-4.1.14-3.3.x86_64.
Samba is configured to have the server act as a member server in a 
Windows Activedirectory domain.
wbinfo -u and getent passwd work fine.  getent passwd shows local and 
domain users.

However, setfacl -n -R -m u:userX:rwx /testpath fails if userX is a 
domain user, but succeeds if userX is a local user.  Using different 
specifications for userX ('domain\userX') still fail.

Same testing, with almost identical smb.conf and other settings, works 
just fine on a opensuse 13.1 machine with ext4 running 
samba-4.1.14-3.2.i586

Any ideas or help in resolving the failure on opensuse 13.2 are much 
appreciated.
