Internal Server Error 500 when CASifying Zimbra 6.0
I trying to CASifying Zimbra 6.0. My OS zimbra server is ubuntu server 8.04 TLS with zimbra 6.05. And my Cas Server is Ubuntu server Karmic 9.10.
I follow instruction at CASifying Zimbra 6.0 - Zimbra :: Wiki.
When I enter webmail https://mail.example.com then redirecting to cas server https://cas.url.com:8443.
After I enter username & Passwd then redirecting again to https://mail.example.com and show "internal server error 500".
I have checked log at /usr/local/tomcat/webapps/cas.log and at /var/log/zimbra, Nothing weird.
What should i do ? any suggestion would be greatfull :)
