[Samba] force group does not work

[Leander S.]

Hi

I set up a samba 4.1.4 server on the latest FreeBSD RELEASE 10. 
Unfortunately it doesn't seem to consider the option force group. After 
hours ofresearch I couldn't figure out what I'm still missing. unix 
extensions is set to no. Setting the debug level up to 10 also didn't 
help ;(
Is this a bug or is there simply a mistake in my setup?

When
*valid users = @Groupname*
is set, then I don't have access to the share at all anymore.

As funny as it sounds, but
*force user* **= *MyUsername*
is working as expected.


id -Gn MyUsername
MyUsername Groupname

getent group Groupname
Groupname:*:2004:MyUsername,Groupname

Any help would be greatly appreciated ;)
