samba - Oct 2015 - samba4 object named "domain admins" not found error

I'm logged into a Windows 7 client using the domain Administrator 
account (not the local admin). I'm using the Computer Management | 
System Tools | Shared Folders | Shares  the right click on the share and 
select Properties to set permissions for a share. I want to add the 
domain admins and domain users to the basic share permissions (Everyone, 
CREATOR OWNER & CREATOR GROUP) but when I try, I get the error mentioned 
on the subject line.

Similarly, when I use the Security tab instead of the Share Permissions 
tab, I can't add Domain Admins although Domain Users is already there.

Similarly, when I try to add my domain user account to the permissions 
for a file on the share (right-click on the file in Windows Explorer, 
properties, security), I get the same error.

Any idea what's going wrong?

Apparently Samba didn't like my domain being "dental" and the
realm
being "rossland.dental". I switched things so that the realm is now 
"office.rossland.dental". The domain shows up as "office".
