No offense intended, but are you sure that you know what you are
talking about? The whole point of saslauthd is that it runs as a
different user and can therefore authenticate against databases that
the exim user cannot access. Apart from that the problem is that exim
cannot connect to a unix socket. I fail to see how changing the uid of
a different process will influence the access rights of the exim
process on an entity in the file system.
