How to authenticate Users in different Application with one Auth0 Application?

Hi!

Following Scenario:

  • Several instances of one application running in different user namespaces
  • We want to enable login for those application with one Auth0 Application but Callback URLs differ between all instances
  • Example: app.example.com/id1 and app.example.com/id2 and so on
  • Under app.example.com nothing is served

This approach would work if we add corresponding entries to the callback urls of the Auth0 Applications. But: those applications are created by users and will exceed the number of 100 entries. We’ve already used a host-based approach (id1.app.example.com, …) but this leads to other issues so we are looking for another approach.

Do you have an idea how to solve that problem? There is no central instance of this application we can use as central callback url.

Thanks in advance!
