Back up a step and I think you'd find that those companies had mainframe X.500 systems that predate any PC or unix implementations because at the time only a mainframe had the necessary capacity. Some may still be running the master copy on mainframes. Remember that the L in LDAP means 'lightweight' which only makes sense in comparison to X.500, and that from the start LDAP was designed to work as a tcp front end query mechanism to X.500 directories as well as a standalone database for smaller systems. -- Les Mikesell lesmikesell at gmail.com
