Kerberos Authentication via Apache

[scmoseman@gmail.com]

Re: RHEL 3, Krb5 1.3.3, Apache 2.0, and mod_auth_kerb.

The server has joined the Windows domain, no problems.
The Kerberos tickets are setup for Apache, works good.

Here's an example of an .htaccess file for a website:

AuthType Kerberos
AuthName "MYDOMAIN"
KrbMethodNegotiate on
KrbAuthoritative on
KrbVerifyKDC off
KrbAuthRealm MYDOMAIN.COM
Krb5Keytab /var/kerberos/krb5kdc/http.keytab
<Limit GET POST>
require valid-user
</Limit>

The website authenticates against the Windows domain.
But it uses a pop-up box for the login authentication.
I'm under the impression that it should use Kerberos
tickets and get my domain login info without the need
to request it from me.  I have seen it before, but I'm
at a road block trying to figure out what I need to do.

My IE is setup with "Integrated Windows Authentication"
and the website is even in my "Local intranet" zones.
Is there another step that I am missing on the Apache?

Thanks,
Scott
