Cannot join Active Directory in TrueNAS-12.1-MASTER-202102080538

No, https://ixsystems.atlassian.net/browse/NAS-109386#icft=NAS-109386 is not fixed.

Trying to join domain with latest build/updates, still the same issue:

I have another FreeNAS-11.3-U5 on the network, joining the domain works without problem...
