This statement is false because LDAP, in its basic form, does not guarantee the encryption of data in transit. LDAP transmits data in plaintext by default, which can be intercepted and read by unauthorized parties. To secure LDAP communication, one must use LDAP over SSL (LDAPS) or start a Transport Layer Security (TLS) session over the standard LDAP connection to encrypt the data in transit. Therefore, additional configuration or the use of supplementary protocols is necessary to ensure data encryption with LDAP.
