Cannot Log in Using Google Apps Login for New User

After putting in the domain name it goes to the Google Apps login screen.  After inputting Google Apps login the screen shows "Loading... please wait", then just goes back to https://www.zoho.com/creator/.  I have tried this across all browsers and OS's.

I'm not sure if it is relevant but I shared a form with this user before signing him in.
