Can't access shares using AD-users

I've come over a problem that happens when i try to login to my server with my mac. TrueNAS has a external domain controller that it communicates with. (it says HEALTHY)

The problem accurs when i try to open a share. The share is set up with 0777 access - to me this does not make any sense. When i disconnect from AD and try to login with a local account the share opens right up without problem.

Problem accues on windows and macOS. 

My fix now is that i use local users and hope this is a quick-fix. 

debug is attached.
