Integration of CAS in shiro authentication

Trying to create SSO authentication in zeppelin using CAS in SHIRO. I have created CAS server on http://localhost:9090/fae-cas/login and in this added json file to add zeppelin service. Now zeppelin server is started on http://localhost:8080/ . But when i'm hitting http://localhost:8080/ it is not getting redirected to http://localhost:9090/fae-cas/login, it starts Zeppelin server is started with login button at right button. If i try to login into zeppelin as http://localhost:9090/fae-cas/login then select zeppelin from list of services it redirect me to http://localhost:8080/ but ask login credentials again. I have attaching zeppelin service json file and shiro.ini file.
