Currently MAS supports local (DB) passwords compat login. Passwords provided by REST providers (e. g. MA1SD) are not supported yet. I'm working to make this configurable so if a REST password provider is filled in config.yaml, then compat login will happen against the REST password provider.

Hello,
I'm working to make (soon) a PR on this.
