I need to customize the TMG login page by adding a dropdown field to the usr_pwd.htm page below the password textbox and also appending a value to username based on the current dropdown selection and also defaulting to a specific domain so the user does
not have to type it (this is to be done in addition to modifying the text)...can it be done by modifying the TMG login page?
So far I have only seen guides on how to modify simple stuff such as strings, colors, graphics, etc...any guides or guidance out there to do some more serious modifications?
Thanks,
Igor
