If enabled, allows the use of cleartext passwords on the wire.

By default, the use of cleartext passwords requires a TLS/SSL encryption
layer to be negotiated prior to any cleartext authentication mechanisms
being advertised or allowed.  To require a TLS/SSL encryption layer to be
negotiated prior to ANY authentication, see the *tls_required* option.
