SAML, Simplified.
SAML has a bit of a reputation. For many developers, it lives in that shadowy corner of the B2B internet where XML still rules and stack traces seem to go on forever. If you've ever had the misfortune of debugging a malformed <Assertion>, you know the pain. But here's the thing: it doesn't have to be a nightmare.
At Phase Two, we provide managed hosting and enterprise support for Keycloak, a leading open-source Identity and Access Management platform. And while OIDC has become the default for most modern applications, SAML is still alive and well—especially in enterprise environments.
This post is a gentle (and opinionated) introduction to what SAML is, how it works, and why it still matters particularly if you're implementing SAML SSO in Keycloak.
