Users aren't able to register using non-google auth

[justincorrigible]

As noticed earlier this week, some users who are invited to a project using their corporate/institutional email addresses aren't able to register/sign up on the enrolment app.
This is due to the fact that our Auth system relies solely on Google auth, which is not set up to allow using accounts from other mail servers.

We require analysis on how to enable said users, so they can join the projects they've been invited to.

From Jared:
Yeah so the gist of enrolment adding collaboratorys to a project is that the PI can invite any old email address, but if that email address is not enabled for google authentication (like an institution email address that isnt integrated with google) then you are shit out of luck and can never complete registration

And even if you try to use that invite link to a non google enabled auth email address with a different google enabled auth email address, you are presented with an error from our app

This user request is no longer valid, please contact your PI if you believe this is an error.
