If you have bought a single sign-on (SSO) product, how do you know that is operating correctly? That seems like a simple question, but answering it isn’t so simple. Configuring the automated sign-ons will require understanding of the authentication protocols they use. You will also need to know how your various applications use these protocols—both on-premises and SaaS—to encode them properly in the SSO portal. It would be nice if you could run an automated testing tool to find out where you slipped up, or where your SSO software is failing. That is the subject of this post.
