I'm building several App's or Modules (Each got its own Project or might be a solution) and I need to develop a central core module that acts as a configuration App as well as the main login portal and users management (Using the built-in Identity 2.0)
I need a hint or a road map on how I can allow that functionality so when a user requests a specific module (Might be on a completely another URL, Database or Machine), he'll be redirected to the login page and then return back to the requested url. Of course I need to not include the same login mechanics and controllers in each and every project.
PS: I still need to use the normal Identity User Role check in the Applications/Modules like usual.
I decided to go with IdentityServer4
There is a learning curve here but I decided to go ahead as it will be a better solution in the future.
