Given that ssl_var_lookup() is available for use in other modules, and
provided that in addition SSL_CLIENT_S_DN_n, we would export an
additional variable with the chain length (SSL_CLIENT_CERT_CHAIN_LENGTH
or similar), wouldn't it be possible to do the manipulations required by
mod_authnz_ldap in that module? mod_ssl really seems the wrong place to
me for implementing application-specific requirements (such as these
"matryoshka doll"-style subject DNs).
