Origin of LDAP
According to Tim Howes, co-inventor of the LDAP protocol in 1993, the Lightweight Directory Access Protocol (LDAP) was created to provide low-overhead access to the X.500 directory. Then later, LDAP has been highly successful. It has become the go-to internet directory protocol for a large number of leading software applications. In fact, LDAP was so successful that LDAPv3 (the third version of LDAP) was proposed and accepted as the internet standard for directory services in 1997. LDAP itself remains a widely used model for various internet standards up till now.
