[Samba] autorid broken in samba 4.9?

[L.P.H. van Belle]

Show the servers there smb.conf that might help. 

And your using autorid.. 
https://wiki.samba.org/index.php/Idmap_config_autorid 

Drawbacks: User and group IDs are not equal across Samba domain members.

TC84\administrator:*:1100500:1100513::/home/administrator at TC84
TC83\administrator:*:1200500:1200513::/home/administrator at TC83

1200500-1100500 = 100000

idmap config * : rangesize = 100000
 The default value is 100000 ! 

So this looks normal.. But i never used autorid so, im sure if im wrong
Someone will correct me ;-) 



Greetz,
