Hi all,
we are facing a strange issue about trust domain user issue.
In the beginning. we are using samba-winbind integrated with Window
AD(Server 2012r2 and Server 2008R2), they are working pretty well.
but recently， the winbind client cloud not get the correct trust
domian's user group info as well,
like: id A\\user only show:
uid=16077216(A\user) gid=16077216(A\domain users)
groups=16077216(A\domain users)
there should be more groups.
and we try both version of samba.
from wbinfo --online-status
the samba Version 3.6.23-36.el6_8 show: domain A online
and when we try login via A\\user. it will show below error message:

I am sure A\user is not locked. it's so strange.
and samba Version 4.6.2 show domain A offline, but still can do id stuff.
what we have changed was upgrade Server2008R2 to Server 2016. I don't know
if this impact.(and we couldn't downgrade the windows so far)
and below are what we have try,
leave domain and rejoin. not working.
clean samba cache. not working.
build new server and join to the AD. not working.
anyone know anythings about this problem? thank you.
