CASifying Zimbra 6

[desport]

Hello,

I've followed the tutorial on this page :
https://wiki.jasig.org/display/CAS/CASifying+Zimbra+6.0

It doesn't work :

HTTP ERROR 500

Problem accessing /zimbra/public/preauth.jsp. Reason:

INTERNAL_SERVER_ERROR

I don't know where is the mistake. Any idea ?

Thanks.

The CAS doesn't work for me. Nobody can help me.

Is it possible to disable preauth ?
