What port does LDAP use?

Explanation:
LDAP uses port 389 by default. This protocol for directory services communicates over TCP to ensure reliable delivery of lookups and binds, making 389 the standard port you’ll see in most deployments. If LDAP is secured with TLS, it typically uses port 636 (LDAPS). The other ports shown correspond to HTTP (80), SSH (22), and HTTPS (443), which are not LDAP ports.
