a few questions about SSL module

[Manlio Perillo]

Hi.

I have two questions about SSL module (well, about SSL in general):
1) Is it reasonable to use the same certificate for both ssl_certificate
    and ssl_client_certificate?
2) In case ssl_verify_client is on, is it reasonable to
       set $http_remote_user = $ssl_client_s_dn;
    ?


Thanks  Manlio Perillo
