[Dovecot] LDA without lookup as non-root?

Hello,
I'm having some problems getting LDA to work without
userdb lookups and have a few related questions. This system has all
users in MySQL, each user with unique UID/GID, no local users at all.
Installation is from apt-get.
1) If LDA is invoked without
lookups, is it correct to assume that the "service auth" and "service
auth-worker" can be completely removed from dovecot master
configuration? (I have tried commenting them out and logging into IMAP,
which seems to work, not sure if anyone else needs the auth service)
2)
If LDA is invoked without lookups, will I be unable to use Dovecot
quota plugin? Does it need to have a user lookup to get quota info?
(haven't added quota support, need to take this one step at a time)
3) The interesting part -- I am invoking LDA from Maildrop. See:
http://thread.gmane.org/gmane.mail.imap.dovecot/65473
So
when invoked, Maildrop has already dropped to the destination UID/GID
and the needed paths are available in the environment. However, using
as many permutations of calling LDA as I can think of (based on http://wiki2.dovecot.org/LDA ), I always get this:
(command line usage error. Command output: lda: Fatal: Couldn't lookup our username (uid=2500) )
The
UID is correct for the target user. If I add "-d $LOGNAME" to my LDA
callout, I get permission denied on the userdb lookup, which I guess is
another issue to work out if I want to go with lookups. But right now I
am trying not to. Why does LDA seem to try for a lookup even when I
follow the wiki instructions how to call it without a lookup?
3.5)
Related question, my users have separate homedir and maildir, both
paths are looked up by Maildrop. I think I need to call LDA with
"HOME=$DEFAULT dovecot-lda -f $FROM". Is this correct?
