Hi list,

This is my domain enviroment and all DC are windows 2008r2

When I used samba-4.0.5, I join my box to domain "HC1" , I  got trusted
domain "CHILD2" in "wbinfo -m".

[/share/Public] # wbinfo -m
BUILTIN
MYBOX
HC1
CHILD1
TREEROOT
HC2
CHILD2

Then I upgraded my box to samba-4.4.4, I lost CHILD2 in "wbinfo -m".
[/share/Public] # wbinfo -m
BUILTIN
MYBOX
HC1
CHILD1
TREEROOT
HC2


In log.wb-HC2 , I found following message:

[2016/07/26 12:02:03.981949,  5, pid=15758, effective(0, 0), real(0, 0),

I compared wireshark pcapng between samba-4.0.5 and samba-4.4.4:
samba-4.0.5:

samba-4.4.4:
http://i.imgur.com/f5bYOeo.jpeg

samba-4.4.4 did not send "create netlogon" , "netlogon binding" and
DsrEnumerateDomainTrust so I can not get "CHILD2" in "wbinfo -m".

I tried to use patch in
https://bugzilla.samba.org/show_bug.cgi?id=11830

After using this patch, samba-4.4.4 can send "create netlogon" and
"netlogon binding" but failed in NetrServerAuthenticate3.

And I got these message in log.wb-HC2:
2016/07/27 16:25:50.602158,  1, pid=18689, effective(0, 0), real(0, 0),

Is there any suggestion that helps to configure samba or DC?

Should I wait for new patch?
