Using the split configuration (which is post-sarge, I think) and exim4
I have
# Local users for whom we want IMAP delivery
localpartlist imap_users = user1:user2
MAIN_TRUSTED_USERS = uucp:cyrus
in a file I dropped under conf.d/main

The localpart list is only because I'm only doing Cyrus for some users
(see router coming up next), and cyrus is a trusted user so SIEVE
redirect will work (though this is not your current problem)

conf.d/850_local_imap_user
imap_user:
  debug_print = "R: imap_user for $local_part@$domain"
  driver = accept
  local_parts = +imap_users
  transport = cyrus

conf.d/50_rb_cyrus
# Deliver to local cyrus IMAP server via LMTP
cyrus:
  debug_print = "T: cyrus for $local_part@$domain"
  driver = lmtp
  delivery_date_add
  envelope_to_add
  return_path_add
  user = cyrus
  socket =  /var/run/cyrus/socket/lmtp
  batch_max = 40

Notice I set the user to cyrus.  If you're trying to do this as
Debian-exim, that may be your problem.

Do you know that SASL is operating properly outside of exim?  It is
famously cranky.
