won't log in

I have redirected and masked a domain name to the WebExplorer Server login page (which is on a totally different domain), but it won't let me log in.  When I type the "real" url, it works.

What's up with that?  My customer needs the masked domain name to be shown. It shouldn't matter if the domai name is masked/forwarded or not.

WebExplorer Server doesn't check the domain name, this should be about your server configuration, I have sent you an email.
