# Client IP Validation Failure Response

Manages the response when [Client IP Validation](com.sun.identity.agents.config.client.ip.validation.enable.html) is `true` and the IP address of an authenticated request does not originate from the IP address used for authentication.

* `true`: Terminate the session and prompt the user to reauthenticate. The authentication mode is managed as described in [Login redirect configuration options](../user-guide/login-redirect.html#table-login-redirect) in the *User Guide*.

* `false`: Return an HTTP 403 Forbidden.

When [Client IP Validation](com.sun.identity.agents.config.client.ip.validation.enable.html) is `false`, this property has no effect.

Default: `false`
