Add support for authenticating MS-SNTP responses in Samba (ntp_signd). Supported is currently only the old MS-SNTP authenticator field. It's disabled by default. It can be enabled with the --enable-ntp-signd configure option and the ntpsigndsocket directive, which specifies the location of the Samba ntp_signd socket.
