#
#  The following policies generate targeted IDs for ABFAB (Moonshot)

#  and that this is called from the inner-tunnel
#

#  Moonshot-Host-TargetedId (138)
#  Moonshot-Realm-TargetedId (139)
#  Moonshot-TR-COI-TargetedId (140)
#  Moonshot-MSTID-GSS-Acceptor (141)
#  Moonshot-MSTID-Namespace (142)
#  Moonshot-MSTID-TargetedId (143)

#  post-proxy and pre-proxy when you use attribute filtering:
#       Moonshot-Host-TargetedId =* ANY,

#  dictionary attacks, therefore should be chosen as a "random"
#  string and kept secret.
