==Protocol overview==A client starts an LDAP session by connecting to an LDAP server, called a Directory System Agent (DSA), by default on TCP and UDP port 389, or on port 636 for LDAPS.
LDAP je vplival na nadaljnje internetne protokole, vključno novejše različice X.500, XML Enabled Directory (XED), Directory Service Markup Language (DSML), Service Provisioning Markup Language (SPML) in Service Location Protocol (SLP).
