Which of the following procedures will test the TLS configuration of your LDAP server?

The `ldapsearch -ZZ` option explicitly instructs the client to attempt a StartTLS extended operation, upgrading an insecure LDAP connection to a secure TLS/SSL encrypted one. By simultaneously capturing network traffic with a packet analyzer, you can directly observe the TLS handshake packets and confirm that the communication successfully transitions from plaintext to encrypted, verifying the server's TLS configuration.

The `ldapsearch -x` option specifies simple authentication and does not inherently force TLS negotiation; without `-ZZ`, TLS might not be initiated if the server allows plaintext or other authentication methods.

The `slapcat` command dumps the local LDAP database to an LDIF file and does not involve network communication or TLS negotiation with a client, making it unsuitable for testing TLS configuration.

`/var/log/ldap_auth.log` is not a standard log file for detailed TLS negotiation; `slapd` typically logs TLS events to the system's syslog (e.g., `/var/log/syslog` or `/var/log/messages`), not a specific `ldap_auth.log`.

While `/var/log/auth.log` contains authentication-related messages, it generally does not provide the granular detail needed to confirm a successful TLS handshake and encryption, which is best observed via packet analysis.
