Are you using the stock Debian versions or something different?

The two threads above focused on the proxyd authentication between the
frontend and backend. Verify that you can proxy authenticate on the
frontend, i.e.:

imtest -v -m plain -a frontend -u <proxied_user> <backend host/ip>

Check /var/log/auth.log on the backend for errors.

Check your mailboxes db on the front end (ctl_mboxlist -d), and make sure
that the frontend can resolve the name of the backend server name that
appears in your mailbox list. For instance, if your mailboxes list claims
that user.jsmith resides on 'backend', you may need to put that in your
/etc/hosts.
