In the UI, via distributed monitoring, it is possible to login to a remote site with a user that does not exist on the main site. However, this was not possible via the Rest-API, as we were checking that the username provided existed on the main site.

With this werk we have changed this behaviour to match that of the UI. The username provided to the Rest-API login endpoint no longer needs to exist on the main site.
