Umm Postgres started in 1986, a good 12 years before OpenLDAP was created, but not really an excuse.
Though OpenLDAP derives from Umich LDAP, which according to its copyright notices is from 1990. (The oldest release I can find is umich ldap-2.0 from 1992.)
Come to think of it, http://www.openldap.org/software/roadmap.html seems to be OpenLDAP's version of a history file, so I think it would be proper to start it off with an item a la
University of Michigan (Umich) LDAP 1.0? - 3.3 (1990? - 1996) The first LDAP implementation, now discontinued. OpenLDAP is derived from the last release, ldap-3.3.
or to include that in the roadmap text about OpenLDAP 1.0.
