The Horizon Security Server is paired to a Horizon Connection Server using a password that is specified in the Horizon Administrator console. This password is entered during the installation of the Security Server, and enables secure communication between it and the Connection Server on the private network. The following steps outline how to generate the password:

1. Log on to the Horizon Administrator console using an AD account that has administrative permissions within Horizon.
2. Navigate to the View Configuration | Servers page within the console.
3. Select the Connection Servers tab in the Servers window.
4. Highlight the Connection Server that you wish to pair with the Security Server, click on the More Commands button, and select Specify Security Server Pairing Password.... In the following screenshot, we have highlighted the HORCON01 Connection Server:

5. In the Specify Security Server Pairing Password window, specify a password and the amount of time it will be valid for. Click on OK when finished. The following screenshot shows the Pairing password:, Confirm password:, and Password timeout: fields:

With the password specified, the installation of the Security Server can now proceed. In the event that the installation cannot be completed prior to the password expiring, simply generate a new password.
