As with the
gss-client program example, the sample server program allows the user to specify a mechanism. However, it is strongly recommended that all applications use the default mechanism provided by the GSS-API implementation. The default mechanism is obtained by setting the gss_OID that represents the mechanism to GSS_C_NULL_OID. Interested readers can refer to the code itself in createMechOid() and read about using non-default mechanisms in Appendix C, Specifying an OID.
