Kerberos and iTunes

[IUDavid]

Hello all,

I've been trying to put a podcast under Kerberos authentication. We've
successfully configured Apache to use Kerberos with a Web browser.
However, when I post a .xml file for the podcast, and use the "itpc://"
protocol, it will bring up iTunes, but will not provide any access to
the podcast file or associated tracks. It says "An unknown error
occurred (500)."

Has anyone ever had success getting iTunes to work with Kerberos?
Thanks,
