It has access to them all, but only exports the first.

If you upgrade to 2.2.x, you could hack ssl_engine_kernel.c by adding:

"SSL_CLIENT_S_DN_OU_0",
"SSL_CLIENT_S_DN_OU_1",

to the ssl_hook_Fixup_vars[] array. This will force the first and
second OU field to be exported to CGI scripts in those named variables.
Note that this won't work with 2.0.x, which doesn't support the _N
suffix.

mod_ssl is integrated into the httpd 2.x tree, so there is no separate
"versino".
