# Server authentication Use the **Server authentication** tab page to specify what happens if server authentication fails. 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. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
