chain.c in back-ldap in OpenLDAP 2.4.x before 2.4.24, when a master-slave
configuration with a chain overlay and ppolicy_forward_updates (aka
authentication-failure forwarding) is used, allows remote authenticated
users to bypass external-program authentication by sending an invalid
password to a slave server.
