Active Directory trust

Hello everyone,

I’m encountering an issue with TrueNAS (CORE) and Active Directory trusts.

  • TrueNAS is successfully joined to the primary AD domain, and everything works fine for the main domain (winbind mapping, GUI, etc.).
  • A two-way trust is configured between the primary domain and the trusted domain (verified directly in AD environment).
  • Configured idmap backend as RID for the primary domain.
  • Set up a separate idmap range for the trusted domain (non-overlapping).
  • Confirmed that wbinfo -u returns users from the primary domain.
  • Confirmed that trust is active and working between domains in AD.

The problem:

  • Running wbinfo -m does not show the trusted domain at all.

Has anyone encountered a similar issue where wbinfo -m doesn’t list the trusted domain?

Hi and welcome to the forums.

What version of CORE are you currently ruining?

Your screenshot shows idmap AD but you mention RID?

Take a look at this Windows Security Update Active Directory Domain Controllers breaks idmap_ad in winbindd

Hi my version is TrueNas Scale 25.04.2.1, I have AD integrated to my main Domain and added RID for trusted domain. If I did something wrong please let me know
