We're having an issue here with CAS. It's currently running in front of our Zimbra email systems.
A user attempts to browse to the Zimbra web UI, logs in through CAS, and gets an error in their browser saying "too many redirects". In the CAS logs (Catalina.out) we see that CAS at times is issuing multiple service tickets...and it seems to coincide with the user receiving the "too many redirects" error. Below is an example, and in this case there were at least 8 tickets issued...just showing a few here. 2011-10-25 20:39:09,427 INFO [org.jasig.cas.authentication.AuthenticationManagerImpl] - <AuthenticationHandler: org.jasig.cas.adaptors.ldap.BindLdapAuthenticationHandler successfully authenticated the user which provided the following credentials: [username: BLAH]> 2011-10-25 20:39:09,474 INFO [org.jasig.cas.CentralAuthenticationServiceImpl] - <Granted service ticket [ST-273941-JcWRA6oSq0m1QthmSTIA-cas] for service [https://zimbra.wiu.edu/zimbra/public/preauth.jsp] for user [JA-BLAH]> 2011-10-25 20:39:11,183 INFO [org.jasig.cas.CentralAuthenticationServiceImpl] - <Granted service ticket [ST-273942-dDZQvmp9GjBV1cW9fJmB-cas] for service [https://zimbra.wiu.edu/zimbra/public/preauth.jsp] for user [JA-BLAH]> 2011-10-25 20:39:12,732 INFO [org.jasig.cas.CentralAuthenticationServiceImpl] - <Granted service ticket [ST-273943-jQ4lWCvFwz1toe7V1bII-cas] for service [https://zimbra.wiu.edu/zimbra/public/preauth.jsp] for user [JA-BLAH]> Anyone seen this before or know what may be causing it?
