Which of the following are valid LDAP client commands? (Choose TWO correct answers.)

`ldappasswd` is an LDAP client utility specifically designed to allow users to change their password within an LDAP directory, interacting directly with the LDAP server for this purpose.

`ldapbrowser` typically refers to a graphical user interface (GUI) tool for browsing LDAP directories, not a command-line utility.

`slapcat` is an OpenLDAP server-side utility used to dump the contents of an `slapd` database, not a client command for user interaction.

`ldapwhoami` is an LDAP client utility that performs a WHOAMI extended operation to determine the distinguished name (DN) of the currently authenticated user, which is useful for verifying authentication contexts.

`slaptest` is an OpenLDAP server-side utility used to test the syntax and integrity of the `slapd.conf` or `cn=config` configuration, not a client command.
