SSO Login Failure After a Tomcat Upgrade

If you have configured Single Sign-On (SSO) with Common Tomcat 7.0, and have upgraded Deployment Automation to a version that uses Common Tomcat 8.0, you must configure Common Tomcat for SSO again, including setting the parameters in the gatekeeper-core-config.xml file. Otherwise, SSO login will fail.

For instructions on setting up SSO, refer to Configuring Common Tomcat for SSO.
