apache and client certificate
 

Hallo:

Apache2.2.22/tomcat6 on CentOS 5.5.

I'm trying to authenticate users using client certificates and send the username to jsp pages.

I can send the field of the certificate to Tomcat with:
and can read the field in the jsp page.

My problem is that SSL_CLIENT_S_DN_CN doesn't have the username. It has an information which can be used to ask an LDAP to get the username.

My question:
- How can I take the field of the certificate and ask an ldap to get the username to send to tomcat?
- Does any know if is there a good forum for apache? (I've to say I always use linuxquestions, but is possible that for very specific themes...)

Thanks

Thanks
