Enabling client authentication

If you enable client authentication, the server validates clients by checking for trusted certificate authority (CA) root certificates in the local key database.

For each virtual host, choose the level and the type of client authentication.


Choosing the level of client authentication

  1. Specify one of the following values in the configuration file on the SSLClientAuth directive, for each virtual host stanza . A virtual host stanza represents a section of the configuration file that applies to one virtual host.  
    None The server requests no client certificate from the client.
    Optional The server requests, but does not require, a client certificate. If presented, the client certificate must prove valid.
    Required The server requires a valid certificate from all clients.

    For example, SSLClientAuth required

    Note: If you want to use a certificate revocation list (CRL), add crl, as a second argument for SSLClientAuth. For example: SSLClientAuth required crl.

  2. Save the configuration file and restart the server.
