In the **If authentication fails** drop-down list, select one of the following options:

* **Connect**. The user can ignore the certificate of the server and still connect.
* **Warn**. The user is alerted about the certificate and still has the ability to choose whether to connect or not.
* **Do not connect**. The user is not allowed to connect.
