    Hi, We are working on a project, where there are 2 different web applications are used by the same user. Hence we need Single Signon (SSO), so that when a user is logged in one application opens the second application, it should not ask for relogin, if the user have permissions. Our web application is on .net core 3.1 We had implemented SSO using identity 4. we had refereed a sample application (.net core 2.0 and identity 4 server 2.0) and implemented the same. Issues facing 1. Even if a user have permissions for both the applications and logged in to 1 application, when he tries to open the 2nd application, it asks to signin again(ie, it is not authorized) 2. For admin user, which have all the permission, it fails to open the application due to cookie memory issue. We have tried to upgrade the identity 4 server to the latest (4.1), but it through run time error. Please help to resolve the issue.

      If you're talking about IdentityServer[^], you're best source of information is going to be the people that wrote it. There's a "Contact" link in the upper right corner of the site.
