Mutual authentication can be requested before establishing the security context.

An encryption type must be chosen for communication. In old versions of JRE, only DES is supported, so you must config Windows Active Directory to create DES keys for users. The latest JRE updates (from 1.4.2 to 6) already support RC4 which is the default encryption algorithm in Windows.

As for HTTP/SPNEGO, these info may help you

Client is built into JRE:
