From the App store download the Citrix Receiver App
In the Address field you will need to type the full PNAgent Logon Point URL: https://%Domain%/lp/pnagent (NOTE: Be sure to HTTPS and not HTTP. The lp stands for logon Point and is a lower-case “L” not an upper-case “i.”)
Click the Next button

Fill out Username, Password and Domain, then click the Save button
Type your password in the next screen and click OK
