Hi All,
I have a SSO application running through an STS I built. The SSO works great between the STS, RP, and my SharePoint Application. I have a 3rd party system I need to integrate with my STS. This will be hosted on the same domain as the other applications. The easiest route I would think would be to setup the application as a relying party to the STS. However the application is not a .NET application. This application is written in java and our team has very little control. Is there a way to give them the key used to generate the cookie so they can decrypt it? If the 3rd party can get the username, they would authenticate on that.
