I did some work publishing Citrix XenApp 5.x with UAG 2010. When arriving at step 6 of the configuration wizard I wondered how to define more than 4 Citrix Farm Servers. There was no scroll bar at the right of the list box and apparently the UI does not handle more than 4 entries.
To add more than four Citrix Farm Servers, just hit the INSERT key and you will see the scroll bar appearing and a new text field where new servers can be set.
