What is the default port number for unencrypted LDAP connections?

The default port number for unencrypted LDAP (Lightweight Directory Access Protocol) connections is 389. This port is used for standard LDAP operations and facilitates communication between clients and directory services without any encryption or secure tunneling.

When establishing a connection, using port 389 allows clients to perform directory lookups and queries, making it a vital component of many networked environments where directory services are leveraged for authentication, user management, and other organizational tasks.

In contrast, port 636 is designated for encrypted LDAP connections (LDAPS) over SSL, while port 1812 is generally used for the RADIUS authentication protocol. Port 8080 is commonly utilized for web servers or alternative HTTP traffic, but it is not associated with LDAP operations. Understanding these distinctions is crucial for properly configuring and securing LDAP services within a network architecture.
