A few more details:
- If you don't want to depend on server certs, use anon-(EC)DH
Clients and servers must reject TLS connections using such a
ciphersuite but not using a GSS-authenticated application protocol.
- The protocol MUST use GSS channel binding to TLS.
- Use SASL/GS2 instead of plain GSS and you get to use an authzid
(optional) and you get a builtin authorization status result message
at no extra cost, and all while still using GSS.
You get to optimize only the mechanism negotiation, and you get TLS w/
Kerberos (and others) and without PKIX (if you don't want it).
See RFCs 7301, 5801, 5056, and 5929 (but note that the TLS session hash
extension is required).
