Kerberos via HTTP negotiate is also insecure when not used over HTTPS.
In HTTP negotiate, the GSSAPI mechanism (Kerberos) isn't used to protect
the data stream, only to authenticate. So you still need a secure
(Also, negotiate auth does no channel binding, which means Kerberos
provides no additional protection against MITM attacks on the TLS
channel. That just means it's still important for the client to verify
the server cert. I've heard that Microsoft has some extensions to RFC
4559 to do channel binding, but I don't know any details and Neon almost
certainly doesn't have any support for it.)
