[CentOS] Samba 4.1.6

I just installed a CentOS 7 server and ran into a problem with Samba and 
the "force user" option.  Apparently, there was a fix for some "force 
user" issues in the 4.1.6 release.

Is there any likelihood of an update from upstream?  If not, is there 
another repo that provides a more up-to-date version of Samba?
