gssapi-keyex and gssapi-with-mic

I have configured the mac os x builtin openssh server to authenticate just with publickey and when I test the authentication the failure notice looks good except that it mentions along with publickey gssapi-keyex and gssapi-with-mic. What are those two gssapi items? Are they a part of publickey? I looked through the sshd_config file multiple times and didn't see any obvious entries relating to those items. If they aren't something that come along with publickey, should I disable them for security reasons and if so how? Thanks! 🙂

P.S. The openssh server is running on Mac OS X 10.4.11
