SSL/CGI variables question

[Stefan Zasada <st...@ucl.ac.uk>]

Apologies if this has been asked before:

I'm trying to run a perl cgi script in a standalone tomcat container
with ssl turned on.

With the script running under apache, an environment variable
(SSL_CLIENT_S_DN) is set with the DN from the connecting client's
certificate.

Is is possible to pick up a similar environment variable with the cgi
script running under tomcat? I've looked at the list of cgi variables
that are set and it isn't amongst them.

I've looked around for a way to do this but can't seem to find anything.
Any help would be appreciated.

Stefan.

It is usually a good idea to mention your Tomcat version although in
this case it doesn't change the answer.

The best you are going to get is REMOTE_USER and how that is populated
under SSL depends on how your realm is configured.

If you need this, patching the CGIServlet should be easy. If you get a
patch that works, I would be happy to review it for inclusion in the
standard Tomcat CGI Servlet.
