Not finding any information specifically for Zimbra 7.0, I followed
the directions for 6.0 here:
https://wiki.jasig.org/display/CAS/CASifying+Zimbra+6.0 .
The redirection to the CAS server works, but something fails after
that: after about 3 minutes, the browser reports "Internal Server
error", return code 500.
>From what I know of the CAS protocol, and the stack trace shown below
(from the zimbra server, in ~zimbra/log/mailbox.log), the problem
appears to occur when the zimbra server tries to verify the CAS ticket

I searched the web.xml.in file I modified per the directions for
anything that might be interpreted as a br tag, but found nothing.
I've tried this with v3.2.0 and v3.1.12 of the cas-client-core; both
yield the same result. The CAS server I'm using is v3.4.2.
Any ideas what's wrong, and how to fix it?
Thanks
