At least one protocol (GlobalProtect) requires the security checker ("CSD")
script to be invoked during the tunnel/connection phase, rather than the
authentication phase, because the access-enabling mechanism depends on
knowing the IP address(es) of the client in the internal network. See
check_or_submit_hip_report() in cstp.c in OpenConnect.
