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, Mike -- Michael D.
