 subject: GSSAPI forwarded credentials must be encrypted in session key
 target_version: 1.8.4
 tags: pullup

 When IAKERB support was added, the krb5_mk_req checksum function
 gained access to the send subkey.  This caused GSSAPI forwarded
 credentials to be encrypted in the subkey, which violates RFC 4121
 section 4.1.1 and is not accepted by Microsoft's implementation.
 Temporarily null out the send subkey in the auth context so that
 krb5_mk_ncred uses the session key instead.
