Question

I have an IdentityServer4 application running with ASP.NET Identity. I want to use that so users from another application can login through my remote identity server.

Answer 1

2 Things to note for this issue:

1. In the client application ,'ClientSecret' should be the 'unencryptedvalue' - plaintext.('secret' in following example)
2. While doing the configuration for all clients, in identity server, please check the secret.Type, it should be 'SharedSecret'.

Example:

Secret secret = new Secret("secret".Sha256(), "Description");
secret.Type = "SharedSecret";
