``A caller may provide the value NULL (GSS_C_NO_NAME) for
desired_name, which will be interpreted as a request for a
credential handle that will invoke default behavior when passed
to GSS_Init_sec_context(), if cred_usage is GSS_C_INITIATE
or GSS_C_BOTH, or GSS_Accept_sec_context(), if cred_usage is
GSS_C_ACCEPT or GSS_C_BOTH.''

If GSS_C_INITIATE is specified, then get credentials from the
default cache. If we don't have any, then try using the keytab.
If GSS_C_ACCEPT is specified, just note our principal name and
open the keytab.
If GSS_C_BOTH is specified, do both of the above.
