| When the cache server receives client credentials during the handshake operation, the server authenticates the client with the callback configured in the `security-client-authenticator` system property. The handshake succeeds or fails depending on the results of the authentication process. |
| |
| Here is an example of how you could configure `security-client-authenticator` in the `geode.properties` file: |
| |
| ``` pre |
| security-client-authenticator=templates.security.PKCSAuthenticator.create |
| ``` |
| |
| In the preceding configuration sample, `PKCSAuthenticator` is the callback class implementing the `Authenticator` interface and `create` is its factory method. |
| |
| The following example shows an implementation of the static `create` method: |
| |
| ``` pre |
| public static Authenticator create() { |
| return new PKCSAuthenticator(); |
| } |
| ``` |
