1 of 14 version

a standardized directory access protocol that allows queries to be made of directories (specifically, pared down X.500-based directories). If a directory service supports LDAP, you can query that directory with an LDAP client, but it's LDAP itself that is growing in popularity and is being used extensively in online white and yellow pages. Main access protocol used by Active Directory. It operates, by default, at port 389. LDAP syntax uses commas between names. LDAP breach can be quite serious, so many use secure LDAP (LDAPS), all communications are encrypted with SSL/TLS and port 636 is used.
