LDAPS
LDAPS — LDAP over TLS
Directory · Intermediate
Directory access wrapped in transport encryption, commonly on port 636. The name survives from an older encryption label, but current deployments use modern transport encryption.
It is the protected form of a directory query. Clients should check the directory server's certificate so they are not handing lookups to an impostor.
Example: A server binds to the directory on port 636 and verifies the certificate before searching for a user.

Common misconception
- The historical name mentions an obsolete encryption protocol, but a current deployment should negotiate modern transport encryption.
