I've managed to get TrueNAS connected to Active Directory and created a share that I can access from an AD account on a Windows client just fine. However when I try to mount the share on Ubuntu Server 24.04 I keep getting permission/logon failure.
In my fstab entry I've tried every combo I can think of.
domain=domain,user=user,password=pass
domain=domain.local,user=user,password=pass
user=domain\user,password=pass
user=domain.local\user,password=pass
I've also tried a separate credentials file with every one of those combinations as well as versions 2.1 and 3.0. I've got no problem mounting shares from the Windows server without even specifying the domain.
At this point I'm pretty sure I'm missing a setting on TrueNAS but no idea what. Any ideas?
I understand that, I've tried both domain=CompanyWork and domain=CompanyWork.internal in my cred file and directly in fstab both result in the permission error when mounting the TrueNAS share but work just fine when mounting a share provided by Windows Server.
