I built a replacement TrueNAS server and are preparing for production use. It will primarily be used for media storage and local streaming. I have replicated the datasets from the existing TrueNAS server. While creating some more SMB User accounts I keep getting a validation error: “USER_noel: passdb.tdb lacks expected key”.
I have searched for this error online and while not getting an exact match, an AI summary mentions deleting /var/db/system/samba4/private/passdb.tdb and if that does not exist deleting secrets.db. In my case, passdb.tdb does exist in that location (I am logged into the shell as local as local admin). I have listed below the possible AI resolution and the full Validation Error. I hope someone may help me otherwise it’ll be a pain to reinstall TrueNAS.
Possible AI resolution
If the passdb.tdb file is missing or corrupted, a common workaround is to remove the file and regenerate it. This can be done by stopping the SMB service, removing the file at /var/db/system/samba4/private/passdb.tdb, and then running midclt call smb.synchronize_passdb -job to rebuild the database. However, this approach should be used cautiously, as it may affect existing user authentication data. In some cases, the secrets.tdb file may also need to be deleted if passdb.tdb is absent, though this is less common. Ensuring that all SMB-enabled users have valid passwords is essential to prevent the passdb.tdb from failing to initialize.
