Your problem is 'what mechanism is your frontend using to connect to
your backend'? Generally, there are a couple to choose from, and if
you don't specify it, the frontend is just going to choose one
(generally GSSAPI).

Generally, if you backend has anything other then 'sasl_mech_list:
PLAIN', then the frontend will choose a different mechanism (at
least in my experience) to use.

You can force a frontend to use a specific mechanism, but this
currently doesn't work with PLAIN due to a bug (I believe).

Anyhow if you are able to, set 'sasl_mech_list: PLAIN' in your
backend and see if the connection works from the frontend to the
backend.
