allowplaintext: no and aggregates

We are running a murder aggregate:

        Front-end db
        Three front-end servers
        One back end server

Starting next year we are no longer permitting unencrypted connections 
(long time coming).  Our supported authentication mechanisms are:

      sasl_mech_list: PLAIN LOGIN

When I change allowplaintext to "no", will the back-end and front-end 
servers be able to communicate with each other?  Or, do I need
to add an additional non-plain authentication mechanism?  Will the 
db-server require plain-text logins?

Thank You,
