Office 365 Single-Sign-On

In order to provide Single-Sign-On, Lanteria uses IdentityServer4 and Microsoft Entra ID. IdentityServer is a middleware that adds the spec compliant OpenID Connect and OAuth 2.0 endpoints to an arbitrary ASP.NET Core application (http://docs.identityserver.io/).

Web app / API application must be created in Microsoft Entra ID and granted delegated permissions to sign in and read the user profile.
