I'm confused why you're seeing a change, since in my experience it's been
this way for quite some time. Firefox used the final hostname, whereas IE
always used the URL name. When we deployed Negotiate-Auth with
mod_auth_kerb, we had to add both principals to the server keytab. Many
other people had the same issue, as discussed on the mod_auth_kerb mailing
list, which is why mod_auth_kerb added an option to use any principal in
its keytab. This all happened back in 2007 for us.
