How to get a remote user from the mod_perl + SSL?

[Wong, Connie]

Hello,

I'm running mod_perl with Apache-SSL on Solaris 8. 
I setup a self-certificate for the basic authentication.
I want to get the login name from the client (REMOTE_USER). 
In CGI, there is an environment variable $ENV{REMOTE_USER} that I can use.
In mod_perl with SSL, how do I get the remote user after the user was
validated?
Can someone provide an example how to get it?

Thanks in advance,
Connie
