SSLVerifyClient require

[SergioY]

Hi all, i'm new in this forum although i have some experience with Parallels Plesk, and on the other hand with SSL. I need to perform client authentication via certificates. I've made this installation several times but not with Plesk.

SSL without client-cert authentication works ok, but i don't know how to perform client authentication via certs.

- CA certs that signed client certificates are appended in "CA Certificate" field, into the server certificate configuration, at Plesk panel.
- vhost_ssl.conf contains exactly the following:

SSLOptions +StdEnvVars +ExportCertData
SSLVerifyClient require
SSLVerifyDepth 10

But when i try to connect, any of my browsers ask me to select a client certificate, which is correctly installed. I obtain an error:

- Firefox: ssl_error_handshake_failure_alert
- Chrome: Error 107 (net::ERR_SSL_PROTOCOL_ERROR)
- IE can't show the page

Any help would be grateful.

Best Regards
