Accessing SSL environment variables?

[suppressed (Hadmut Danisch)]

Hi,

another problem with porting an older authentication script:

The script used to fetch the certificate details set from the SSL module 
under Apache1.3 with some code like

  $r->subprocess_env;   # initialize
  $envs   = $r->subprocess_env;
  $dn     = $r->subprocess_env('SSL_CLIENT_DN');
  $cn     = $r->subprocess_env('SSL_CLIENT_CN');


it worked. 

Now, under Apache2.2, I can access only a few variables like HTTP_... or
SERVER_... variables, but not the varialbes set from the SSL module. 

(The SSL option StdEnvVars is set, the variables can be seen from PHP
programs.)

regards
