8.Click Cipher Settings.

The Cipher Preference dialog box opens. By default, all ciphers are selected.

9.Set the preferences for client authentication.

Do not allow client authentication. With this option, the server ignores the client's certificate. This does not mean that the bind will fail.

Allow client authentication. This is the default setting. With this option, authentication is performed on the client's request. For more information about certificate-based authentication, see Section 6, “Using Certificate-Based Authentication”.

Require client authentication. With this option, the server requests authentication from the client.

NOTE

To use certificate-based authentication with replication, then configure the consumer server either to allow or to require client authentication.

10.To verify the authenticity of requests, select the Check hostname against name in certificate for outbound SSL connections option. The server does this verification by matching the hostname against the value assigned to the common name (cn) attribute of the subject name in the being presented for authentication.

By default, this feature is disabled. If it's enabled and if the hostname does not match thecn attribute of the certificate, appropriate error and audit messages are logged. For example, in a replicated environment, messages similar to these are logged in the supplier server's log files if it finds that the peer server's hostname doesn't match the name specified in its certificate:

[DATE] - SSL alert: ldap_sasl_bind("",LDAP_SASL_EXTERNAL) 81 (Netscape runtime error -12276 -

Unable to communicate securely with peer: requested domain name does not match the server's

certificate.)

[DATE] NSMMReplicationPlugin - agmt="cn=to ultra60 client auth" (ultra60:1924): Replication

bind with SSL client authentication failed: LDAP error 81 (Can't contact DAP server)

Red Hat recommends enabling this option to protect Directory Server's outbound TLS/SSL connections against a man-in-the-middle (MITM) attack.
