What command is used to add a certificate in LDAP?

The command "configure-certificate" is used to add a certificate in LDAP because it specifically refers to the configuration management of certificates within the LDAP environment. The term "configure" implies a setup or alteration of existing settings, which is precisely what is needed when integrating a new certificate for secure communications. It ensures that the LDAP server recognizes and can utilize the new certificate for secure transactions, enhancing the security infrastructure of the environment.

This command reflects an established convention in systems management, where "configure" is often paired with the task of adding or modifying configurations. As such, it aligns with the operational needs of proper certificate management in an LDAP context. The other options either do not match standard command syntax for LDAP operations or do not convey the specific action of adding a new certificate correctly.
