Which port is associated with the Lightweight Directory Access Protocol (LDAP)?

The Lightweight Directory Access Protocol (LDAP) is primarily associated with port 389. This port enables clients to communicate with directory services, allowing them to query and modify directory entries effectively. LDAP is widely used for accessing and maintaining distributed directory information services over an Internet Protocol (IP) network, which is critical in environments where user access and authentication management are essential, such as in identity management or authentication systems.

Each of the other ports listed serves different functions. For instance, port 53 is used for the Domain Name System (DNS) service, where it resolves domain names to IP addresses. Port 3306 is commonly associated with MySQL, a database management system, while port 1080 is used for the SOCKS protocol, which provides network proxy services. Understanding the specific functionalities of these ports is crucial in network management and security contexts.
