Install a license on Citrix Gateway

After you successfully download the license file to your computer, you can then install the license on Citrix Gateway. The license is installed in the /nsconfig/license directory.

If you used the Setup Wizard to configure the initial settings on Citrix Gateway, the license file is installed when you run the wizard. If you allocate part of your licenses and then later, you allocate an extra number, you can install the licenses without using the Setup Wizard.

1. In the configuration utility, on the Configuration tab, in the navigation pane, expand System and then click Licenses.

2. In the details pane, click Manage Licenses.

3. Click Add New License, then click Browse, navigate to the license file, and then click OK.

   A message appears in the configuration utility that you must restart Citrix Gateway. Click Reboot.

Set the maximum number of users

After you install the license on the appliance, you need to set the maximum number of users that are allowed to connect to the appliance. You set the maximum user count in the global authentication policy.

1. In the configuration utility, on the Configuration tab, in the navigation pane, expand Citrix Gateway and then click Global Settings.

2. In the details pane, under Settings, click Change authentication AAA settings.

3. In Maximum Number of Users, type the total number of users, and then click OK.

   The number in this field corresponds to the number of licenses contained within the license file. This number must be less than or equal to the total number of licenses installed on the appliance. For example, you install one license that contains 100 user licenses and a second license that contains 400 user licenses. The total number of licenses equals 500. The maximum number of users who can log on is equal to or less than 500. If 500 users are logged on, any users who attempt to log on beyond that number are denied access until a user logs off or you terminate a session.

Verify Universal license installation

Before proceeding, verify that your Universal license is installed correctly.

To verify installation of the Universal license by using the GUI

   In the Licenses pane, you see a green check mark next to Citrix Gateway. The Maximum Citrix Gateway Users Allowed field displays the number of concurrent user sessions licensed on the appliance.

To verify installation of the Universal license by using the CLI

1. Open a Secure Shell (SSH) connection to the appliance by using an SSH client, such as PuTTY.
2. Log on to the appliance using the administrator credentials.

3. At a command prompt, type;
