mod_auth_cas + apache 2.2 + reverse proxy

[Chris]

Hi all,

I'm trying to configure an apache 2.2 reverse proxy with mod_auth_cas.

My website config (virtual host) is:

<VirtualHost *:80>
ServerName pwiki
DocumentRoot /home/httpd/pwiki
CustomLog plmwiki/logs/access_log common
ErrorLog plmwiki/logs/error_log

ProxyRequests Off
ProxyPass / http://rwiki.company.com/
ProxyPassReverse / http://rwiki.company.com/
</VirtualHost>

<Directory /home/httpd/pwiki>
Options FollowSymLinks ExecCGI
AllowOverride All
order allow,deny
allow from all
</Directory>

and mod_auth_cas was configured like this:

# JASIG MOD_AUTH_CAS MODULE
LoadModule auth_cas_module modules/mod_auth_cas.so

<IfModule mod_auth_cas.c>
           CASDebug On
           CASCookiePath /tmp/
           CASLoginURL https://cas-rd.company.com/cas/
           CASValidateURL https://cas-rd.company.com/cas/serviceValidate
           CASCertificatePath /etc/pki/tls/certs/casserver.crt
           CASValidateServer on
</IfModule>

When I try to login into http://pwiki, I am redirected to 
https://cas-rd.company.com/cas/ with 
service=service=http%3a%2f%2fr.company.com%2f and not http://pwiki

Anything wrong with the config? I didn't found any configuration por CAS 
caching/proxy in http://www.ja-sig.org/wiki/display/CASC/mod_auth_cas.

Maybe mod_auth_cas does not supports proxy CAS ? If so, any news when 
this would be available? Any workaround if so?

Best,

Chris
