Hmm, that's weird. Have you tried restarting apache ?

Yes..but you've just give me the thought of apache2 logs !:

proxy: HTTP: disabled connection for (localhost) should be the issue

This post seems to have a similar problem, and some ideas to solve it: http://stackoverflow.com/questions/4240189/errordocument-not-working-with-local-file (he didn't solve it, but maybe the suggestions would be enough for this problem?).

For the proxy configuration, I'm not convinced that RedHat reads that variable in from /etc/sysconfig... you should check, and restrict this to SLES if it doesn't. You may well be missing the "LoadModule" instructions (AFAIK you have to insert these manually on RHEL/CentOS), see http://www.jedi.be/blog/2009/03/03/using-apache-as-a-reverse-proxy-to-access-tomcat-in-virtual-machines/ for example.

Even with this, the reverse proxy still not working.

On SLES system we add these modules in APACHE_MODULES envvar: "rewrite dav dav_fs proxy proxy_http". Could it be that some of them are not present ?

It shouldn't be needed to install the package mod_proxy_html since the command above are not proof of its installation or use. mod_proxy is already used:

# grep proxy /etc/sysconfig/httpd 
APACHE_MODULES="${APACHE_MODULES} rewrite dav dav_fs proxy proxy_http" 

# grep -R proxy /etc/httpd/

I can conclude that the problem come not from mod_proxy module. Nevertheless, it seems that SELinux as part in it. Disabling it have resolved the problem and the login page appears:

setenforce 0

But actually I can't reproduce the bug since jetty don't want to start propeprly with this error:

nested exception is java.io.FileNotFoundException: /opt/rudder/etc/licenses/licenses.xml (No such file or directory)

Err... this is normal, I've forgotten to initiate some actions with rudder-init.sh.

The problem was only SElinux and it worked since I deactivated it with:

setenforce 0

I wasn't sure of the fix since my test VM was so extremely slow that it give me impression that jetty didn't start.

I suppose the only fix we can do for now is to inform users in the documentation that SELinux should be off.
