Sagar, Too many redirects means that the ST/token can not be validated. The client app must send the ST to cas for validation. So either cas is unable to verify the ST or it does not receive it. This could be the result of many things. Start by setting cas server logs to debug. You will want to make sure your servers have clocks synced and you are using https (if self signed certs, you may have to add them to the java keystore).

Do you need this SSOController? Maybe look at the spring documentation to see how they suggest configuration.

If your application is running on WebSphere Application Server you may be able to resolve this problem by setting com.ibm.ws.webcontainer.invokeFlushAfterService to false It looks like I am getting logged in but getting rendered to error page for some reason.

Also I was looking at the server logs and found : 2020-11-04 12:16:05.770 ERROR 13281 --- [nio-8443-exec-4] o.s.b.w.servlet.support.ErrorPageFilter : Forwarding to error page from request [/] due to exception [org.springframework.security.authentication.AnonymousAuthenticationToken cannot be cast to org.springframework.security.cas.authentication.CasAuthenticationToken] java.lang.ClassCastException: org.springframework.security.authentication.AnonymousAuthenticationToken cannot be cast to org.springframework.security.cas.authentication.CasAuthenticationToken It looks like token casting is the problem that I have been encountering.

If inb9fnhr.nwmissouri.edu:8443/MyNWSSO/<http://inb9fnhr.nwmissouri.edu:8443/MyNWSSO/> takes you to cas login, it will not be able to receive the ST, but redirect to cas for login in an endless loop. What is happening on the line above the red one in the image?

Hello Ray, I have configured my Spring Boot App but I think the problem is when the CAS redirect to my webapp with Service Ticket my web app is not revalidating the ticket to CAS server again. The reference that I have taken for this webapp is from https://medium.com/@venkateshpnk22/single-sign-on-in-cas-client-setup-with-spring-security-b51a7e70294d Also I have attached the error when I hit the inb9fnhr.nwmissouri.edu:8443/MyNWSSO/<http://inb9fnhr.nwmissouri.edu:8443/MyNWSSO/> it render to sign in and after sign in I got 404.
