OK, I guess the next step is to see whether the dovecot auth process
is able to read the passdb file.  Does your dovecot auth process have
enough authorization to get/read to these files (check what dovecot/auth
runs as versus the file permissions of your passdb)?  "doveadm user
jeff at foo.com" checks the userdb, and if it coincides with your passdb,
might point out a problem.

Tracing the auth process might also help.
