Hello, since xfce-polkit is really not a part of RHEL shipped and is not maintained by Polkit Devel team, I cannot guarantee you a correct answer. Try to find out if another polkit agent isn't running, e.g. polkit-gnome. If yes, kill them all, then try again. If that doesn't help, try uninstalling them (polkit-gnome, polkit-kde, polkit-qt etc.) and reinstalling xfce-polkit, as there can be only one agent initiated by the session manager (also binaries in /usr/libexec are not supposed to be run by users) Anyway moving this BZ to responsible maintainer. Thank you. Jan Rybar
I don't see any other agents running, just polkitd. $ ps -ef | grep [p]olkit polkitd 14438 1 0 Jul01 ? 00:00:02 /usr/lib/polkit-1/polkitd --no-debug
Bump. Any advice on this issue?
I'm afraid not. Does it work as expected if you login directly to the console? Or is this a headless machine?

My assumption is xfce4-polkit is not of much usefulness without the other Xfce elements. Please try to install a full Xfce desktop and reproduce.
