API to get custom properties?

[#1]

I am using below jQuery code/API to get user details

var global = qlik.getGlobal(config);

console.log("global",global);

global.getAuthenticatedUser(function(reply){

var vUserDetails = reply.qReturn;

console.log(vUserDetails);

});

the above code returns only 2 properties as below

UserDirectory=<<userdir>>; UserId=<<userID>>

How can i get the custom properties for user?
