ansible-ui will support custom authentication methods through some sort of wrapper,
this will depend on that, and should contain any changes needed to get the new UI working with keycloak & standalone-ldap.

(continues AAH-2398)

Additional tasks:

• ensure standalone ldap, keycloak work
• ensure this can be configured at build time, including external login url
• e2e tests - set up environment, write tests (extrernal auth redirects)

(might have some overlap with AAH-2400 and AAH-2401)

This now also links all User management tasks and permission assignment tasks;
and parents all permission checking tasks & Access tabs moving them from the original epics.
