Categories should include at least X-Red-Hat-Extra;Application;System;X-Red-Hat-ServerConfig; (I'm saying -Extra and not -Base because redhat-config-samba is in Base, and we shouldn't have two Samba tools in base. Correct me if these don't overlap.) should be namespaced samba-swat.desktop and moved to /usr/share/applications Comment should be about what the tool does rather than its full name, e.g. "Configure Windows file shares"
Fixed in samba-2.2.5-5
