The support for RDP is completly missing from UP. It did not make it to the new gwtp implementation from the old smart gwt one.
in gerrit: http://gerrit.ovirt.org/#/c/9687/
merged u/s as 84782809b755f562deeab14bbc80f9129ac502bf
as RC is built, moving to ON_QA (hopefully did not catch incorrect bugs when doing this)
closing as this should be in 3.3 (doing so in bulk, so may be incorrect)
