Hesiod came out if project Athena. It was used for posix accounts. Similar function to directory services such as LDAP. Last time I checked (several years ago). There source code was still available if you poked around the CMU FTP servers. It was unavailable via http. Edit, it actually may not have been FTP, it may have been on their AFS volumes. https://en.m.wikipedia.org/wiki/Hesiod_(name_service) https://en.m.wikipedia.org/wiki/Hesiod_(name_service)
