I am not able to figure where to tinker in order to solve this.
CAS is configured with openid whihc uses LDAP as user database and used as authentication for my Jenkins server.
After successful login from CAS, it gets redirected back to my jenkins server page. However on the top right corner where ideally the displayName of the user should be, it shows the openid provider URL as it was provided in the openid configuration using jenkins openid plugin. Please refer to image as shown in the screenshot
