Folks, I'm trying to figure out what's going on in our ASP.NET 2.0 app here. We're using .NET 3.0 WCF to communicate with tons of external web services. So far, we've been using Forms Authentication against our custom store to authenticate users, and when they are authenticated, we issued a SAML token for calling a plethora of webservices later on. Works like a charm. Now, we're about to switch to using an external STS (Security Token Server) to get our SAML tokens from - the users get authenticated against an Active Directory store, we get a SAML token for the user principal, and then off we should go. Should - because on the call to "RedirectFromLoginPage" in the Forms auth mechanism, we now suddenly get an error: "Unable to encrypt the authentication ticket. Try changing the decryption key configured for this application." Any ideas what the heck that is, where it comes from, and how to deal with it?? Any hints and pointers would be most welcome ! Thanks Marc |
