If you enable client authentication, the server validates clients
by checking for trusted certificate authority (CA) root certificates in the
local key database.
About this task
For each virtual host, choose the level of client authentication:
Procedure
- 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
and returns a 403 status code if no certificate is present. |
Required_reset |
The server requires a valid certificate from all clients,
and if no certificate is available, the server sends an SSL alert to the client.
This enables the client to understand that the SSL failure is client-certificate
related, and will cause browsers to re-prompt for client certificate information
on subsequent access. This option requires GSKit version 7.0.4.19 or later,
or z/OS V1R8 or later. |
For example, SSLClientAuth required.
If you want
to use a certificate revocation list (CRL), add crl, as a second
argument for SSLClientAuth. For example: SSLClientAuth required crl.
- Save the configuration file and restart the server.
