Why each option
LDAP is considered lightweight compared to X.500 primarily because it has a smaller set of operations and utilizes the TCP/IP protocol stack.
X.500 defines a complex, extensive set of operations and data models, whereas LDAP was designed with a simplified, lightweight set of operations for common directory tasks, making it less complex to implement and use.
X.500 relies on the full OSI protocol stack, which is complex and not widely adopted; LDAP, conversely, leverages the ubiquitous and simpler TCP/IP protocol stack, facilitating easier network integration.
LDAP's lightweight nature stems from *not* using the complex OSI protocol stack, but rather the simpler TCP/IP.
Both LDAP and X.500 support Access Control Lists (ACLs); therefore, this is not a distinguishing factor for LDAP being lightweight.
