Making the display size of this 16 is fine. But the
maxlength is set to 16. This makes no sense, since the
user name can be up to 40 characters long. We have a
few Indians in our office whose names are much larger
than 16 characters! Since we're eventually going to
try to use the NT authentication method, using the full
user name is required.
The required fix is extremely simple: change maxlength
to 40 in the Jsp_BeginEnd/UserLogin.jsp page.
