GMail Sidebar Gadget & Gmail for Domains

[inforr]

I am trying to make Jack's Sidebar Gadget work with my domain hosted on Google Apps.

I am assuming I am on the right track at looking at the google_class.js file

this.gmailUrl   = "http://mail.google.com/mail";
    this.feedUrl    = "/feed/atom";
    this.inboxUrl   = "/?search=inbox&auth=";
    this.searchUrl  = "/?search=query&view=tl&start=0&init=1&fs=1&q=";
    this.messageUrl = "/?fs=1&tf=1&view=cv&search=all&th=";
    this.composeUrl = "/?view=cm&tf=0&auth=";
    this.authUrl    = "https://www.google.com/accounts/ClientAuth";
    this.tokenUrl   = "https://www.google.com/accounts/IssueAuthToken";

I tried changing it to this:

this.gmailUrl   = "http://mail.google.com/a/mydomain.com";
    this.feedUrl    = "/feed/atom";
    this.inboxUrl   = "/?search=inbox&auth=";
    this.searchUrl  = "/?search=query&view=tl&start=0&init=1&fs=1&q=";
    this.messageUrl = "/?fs=1&tf=1&view=cv&search=all&th=";
    this.composeUrl = "/?view=cm&tf=0&auth=";
    this.authUrl    = "https://www.google.com/accounts/ClientAuth";
    this.tokenUrl   = "https://www.google.com/accounts/IssueAuthToken";

I can login succesfully but it doesn't show any of my mail and says I have an unread count of "0" which isn't correct. The Atom feed does work if I paste it into IE. I assume its possibly something to do with the this.authUrl and this.tokenUrl links.

Anyone have any knowledge about the differences between standard GMail and Google Apps for Domains GMail?
