I am not an expert on javascript or polkit, but IINM the second if
rule has wrong syntax, it should be:

if( subject.isInGroup("ejabberd") ) {
return polkit.Result.YES;
}

also, it doesn't need an else bit.


I think you can merge the second if with the first one:

polkit.addRule(function(action, subject) {
var CommandLine = action.lookup("command_line").split(" ");
if ( action.id == "org.freedesktop.policykit.exec" && (CommandLine[0]
== "/sbin/ejabberdctl" || CommandLine[0] == "/usr/sbin/ejabberdctl")
&& subject.isInGroup("ejabberd") ) {
return polkit.Result.YES;
}
});


(I could be very wrong though).
