I think you're mixed up. You don't want to kinit with the HTTP service
principal. You kinit as you on the client. You put the keytab created
by ktpass.exe for the HTTP service principal on the web server (the
HTTP service) and adjust the config accordingly so that is uses it. Now
when you visit the webpage your web browser will get a ticket for the
HTTP service principal from the KDC and send it to the web server. The
web server uses the encryption key in the keytab to decrypt the ticket
thereby verifying your identity.
