I created a Sphinx server as described in the documentation. Have this tested as described via ".. /.well-known/openid-configuration" and I get the JSON message back. Ok, works!.
After that, I did the next step and added the database files as described and registering a client application. If I now start the Sphinx server, the tables are created, the server shows running.
But after insert the URL "...&redirect_uri=http://127.0.0.1" as an answer I don't get the login screen, but the start screen of Windows IIS. I cannot deactivate IIS on my computer because it is used for other programs. What can I do?
