[Samba] I can't join my Linux client to my Samba DC.

[L.P.H. van Belle]

Ok, again, run the debug script on AD-DC and on the member
https://raw.githubusercontent.com/thctlo/samba4/master/samba-collect-debug-info.sh 
And post the info of both here. 
Anonymize where needed. But keep structures the same, meain. 
If you have INTERNAL.REALM.TLD dont change that to REALM because then we might miss parts. 
Then use something like INT.EXAMPLE.REALM
