In my experience with SASL, eliminate postfix from the equation entirely
and use the testsaslauthd tool to test whether your sasl setup works on
it's own. Once testsaslauthd works, then add postfix to the mix.

Unfortunately the alternate usecase support in SASL is virtually non
existent, so you're stuck using strace to tease out the real error that
is preventing SASL from working. If you are truly stuck, use strace (or
your local equivalent) to run testsaslauthd, and pick backwards through
the error messages.

Typical reasons it doesn't work include trying to connect to a socket
using the wrong path, or using the correct path, but without the
permissions being set correctly to access the socket. Also be careful of
assuming the permissions on the socket are correct - double check the
permissions of all the parent directories of the socket as well.

Graham
