=== Comparison: {productname} Image and Red Hat Single Sign-On
The {productname} image version number 7.2 is based on Red Hat Single Sign-On 7.2. There are some differences in functionality between the {productname} image and Red Hat Single Sign-On:

* The {productname} image includes all of the functionality of Red Hat Single Sign-On. In addition, the RH-SSO-enabled JBoss EAP image automatically handles OpenID Connect or SAML client registration and configuration for *_.war_* deployments that contain *<auth-method>KEYCLOAK</auth-method>* or *<auth-method>KEYCLOAK-SAML</auth-method>* in their respective *web.xml* files.

=== Version Compatibility and Support
See the xPaaS part of the https://access.redhat.com/articles/2176281[OpenShift and Atomic Platform Tested Integrations page] for details about OpenShift image version compatibility.
