SMB Mount fails to authenticate AD accounts on High Sirerra 10.13.4

New Contributor

Hello all,
Does anyone have a solution to this?
I have shares on a Mac server both on AFP and SMB.
AFP Shares work fine with both local and Active Directory accounts.
The same shares on SMB only work with local accounts. AD accounts do not authenticate.
It does not matter if I am trying to mount on a Mac or Windows machine. SMB is broken with AD accounts.

The Mac OS X server is running High Sierra 10.13.4
