Get allusernames from userservice plugin

I wanted a way to get the list of usernames from OpenFire so I could compare it with our Active Directory since our OpenFire instance is in the cloud and our AD is private, I can't have OpenFire access it directly. It occured to me if I could modified the userservice plugin to accept another option to get the list of usernames on the server, my goal could be achieved.

I added the following code to UserServicePlugin.java

public String getAllUsers()

    {

        String userNames = "";

        Collection<String> usernamesCol = userManager.getUsernames();

          for(Iterator i = usernamesCol.iterator(); i.hasNext();) {

            userNames += "<username>" + i.next() + "</username>";

        }

        return userNames;

    }

and then modified/added this to the UserServiceServlet.java

        if ((username == null) && (!"getallusers".equals(type))){

            replyError("IllegalArgumentException",response, out);

            return;

        }

     else if ("getallusers".equals(type)) {

                String allUsers = plugin.getAllUsers();

                replyMessage(allUsers,response,out);

            }

The end result is if I use the userservice with a request type of getallusers, I get a result, in the format:

<result>

<username>myuser1</username>

<username>myuser2</username>

...etc...

</result>

which I can then consume/parse in my sync script. I don't want to branch the code for this plugin. What is the correct way to request that this feature be added to the plugin officially?

Thanks,

Steve
