[Samba] when the bug 10928 appears ?

[Yosel Lazaro Vera Gonzalez]

Simple question ? 
I'm using samba 4.2.8 and I have done several migration tests with different Windows Server version . 
In Windows 2008 R2 and the domain functional level in 2008-R2 the bug 1 0928 appears. Then, 
I did the same test with the same environment, and everything works well. 
https://bugzilla.samba.org/show_bug.cgi?id=10928 

Then I did some tests with: 
--> Windows server 2003: functional leve 2003 native 
--> Windows server 2008: functional level 2003 
--> Windows server 2008: functional level 2008 
and everything works well. 

PD: I can't use a newer version of sernet-samba because of economics issues
