External authentication - User privileges

Hi!

I was to experiement with Radius authentication (command_line authentication), so far my script only takes a specific username/password and authenticates a single hard-coded user.
The authentication works, the user logs in, the mayor problem is that the new user, upon HA created its profile, had admin rights within the UI.
Is this a known issue? It it something to do with the configuration? Can I specify the default privileges for the newly created radius-authenticated profiled somehow?

Thanks!

PS. Sorry if duplicate, I couldn’t find a topic specificaly for this issue.
