If I remember right, there are some incompatibilities in the
encrypted 'digest' authentication. So if your web application
uses this authentication type, you may be out of luck :-/

Overall, internal web apps are likely a problem for many
companies. While public web sites should be designed with
multiple browsers in mind, internal web sites frequently 
rely on a company standard browser to make development 
easier. Nothing wrong with that until you decide to change
the standard company browser and find that you may have to
rebuild the web app.

Changing the authentication method is usually not too bad. But
if you use ActiveX/Javascript and such, you may be looking at
more or less a rebuild from scratch.
