Dashboard -> "App Clients" -> "Show Details" -> check "Enable username-password (non-SRP) flow for app-based authentication (USER_PASSWORD_AUTH)"

very good, it worked

Can I use this when I have a Federation (Open Id)?

@LorhanSohaky It works with Open Id, but you'll miss the scopes in the returned token.

Thank you. Works as advertised. Saved me some time tonight.

This is just brilliant! Thanks a lot! I've already spent a few hours on research and debugging session!
