AcquireTokenSilent always Failed to acquire token silently

Question

Using ADAL I have two AuthenticationContext using a Token Cache persisted in SQL.

Using AcquireTokenByAuthorizationCode it writes the Token

Answer 1

I had the same issue in ASPNetCore (1.0) and the reason was that I wasn't storing the authentication token after logging in. I solved it by adding OnAuthorizationCodeReceived in the Startup class and changing my Response ype to ResponseType = OpenIdConnectResponseType.CodeIdToken.

Hope it helps.
