I joined my truenas system to active directory about 8 months ago. I have AD setup in my homelab just for learning purposes. The domain join worked fine back when I first set everything up and I really hadn’t looked at it much since then. I just starting playing around with my network users and my shares and I saw this message about invalid format. Note that the domain is currently working fine and I’m able to update my cache and get tickets, etc.
However, i cant save any settings because the below error comes up for the Name field. I’m also not sure what IDMAP backend is either. How can I fix this? The hypen is valid for a netbios name.
I could potentially rollback to an earlier version to see if the bug still exists. I haven’t noticed it since i did the original domain join which happened without issue. The earliest version I have in Boot Environments is 24.04.0 Aug 2025. However, I did my AD enrollment after that at some point. I do have to do a big storage overall soon. I have some XCP-ng hosts wired into my TrueNAS system which I’m treating as a SAN. What’s the best way to fix this bug or provide more information so it gets fixed?
Sorry, I didn’t make this clear. I think its the hyphen that is breaking things. This is my current domain name in netbios: DOMAIN-NAME\. The field will not accept the hyphen. I tried adding the slash after it to no avail.
