LDAPS
LDAPS, or Lightweight Directory Access Protocol over TLS/SSL, is an encrypted form of LDAP that facilitates secure communication between directory service clients and servers. It operates over standard port 636 and is widely used in enterprise environments for secure directory queries, authentication, and management, ensuring sensitive data remains confidential during transmission..
Lightweight Directory Access Protocol over TLS/SSL (LDAPS) is a secure version of LDAP which performs directory service operations over a secure transport layer. LDAP is an application protocol that enables querying and modifying directory services; LDAPS encrypts this communication to safeguard against interception.
By default, LDAPS communicates over TCP port 636, establishing a TLS/SSL connection prior to any LDAP operations. This ensures that credentials and directory data are encrypted during transit, preventing unauthorized inspection or tampering. LDAPS supports mutual authentication if configured, increasing security by confirming the server's identity to clients.
LDAPS is commonly deployed in Microsoft Active Directory environments or other LDAP-based directories to provide encrypted authentication and directory lookups across enterprise networks. It is typically part of corporate security and access control solutions, helping enforce privacy and integrity within directory-based applications.
