Samba AD Users not showing up in system, Groups do show up

Users from Samba 4 AD don't show up, but groups do.

I've been having consistent problems with my freenas. My windows desktop will eventually no longer be able to access file shares. I'll get an error: "This account is not authorized to connect from this machine."

Usually a logout/login on windows solves it.

Now I'm seeing that there are no users on my free nas from the Active Directory server. The groups are showing up, but not users. Checking the ACL for the samba share is the easiest place to find it. I have attached a screenshot. That group is resolved from the AD server, and the user should be as well, but it is not.
