  • Redirect to home page when visiting user signin pages with
    authentication disabled.
• Add access control checks:
  • Consider new environment variables to enable Attribute Based Access
    Control and get a set of user attributes from a configurable claim in
    the access token.
  • Add attributes to auth store state and include actions to parse and
    check those attributes.
  • Configure protected routes and check attributes before each route
    change, redirecting to the home if the check fails.
  • Modify or hide elements (links, tabs, etc.) based on user attributes.

@djjuhasz, @sevein, @sbreker

I'm struggling with the tests a little more than expected and it's getting late to review and merge, while I work in the documentation. Sorry about that, I'll restore and add more tests in a different PR. Again, I think it makes more sense to review commit by commit.

Looks great @jraddaoui 👍
