Murder without Kerberos?

I haven't tried it with 2.3.6, but PLAIN should work.

I would suggest starting with
sasl_mech_list: PLAIN

in all your imapd.conf files (make sure it says only PLAIN).

and make sure there is no
  force_sasl_client_mech
lines anywhere.

Then make sure you can use imtest (with -m PLAIN and -t ""  (for  
tls)) to connect to backends, and then see if the backends will  
communicate correctly.
