applies for ldap too if you use prefetch.

Subject: LMTP error, mysterious
hi (especially to you, Aki),
so to solve the previous UID issue, i went the full LMTP route.
however,
i seem to be having problems with the prefetch userdb (i'm trying
to
minimize load on the LDAP server). namely, the log says:
Aug 2 00:15:35 rhyno postfix/submission/smtpd[21158]:

(in

(the above is a transcript of a full session i've done over
telneting to
localhost 587 and auth login-ing with valid credentials)
so, i've tested the actual login process, and it works flawlessly,
and
it looks like IMAP is up and running:
Connected to localhost.

this is how i send the test mails:

my concern is these two:
Aug 2 00:15:40 rhyno dovecot: auth: Error:

userdb lookup not possible with only userdb prefetch
Aug 2 00:15:40 rhyno dovecot: lmtp(aik@rhyno.tech): Error: user
aik@rhyno.tech: Auth USER lookup failed
10-auth.conf has these settings:
passdb {
driver = ldap
args = /etc/dovecot/dovecot-ldap.conf.ext
}
userdb {
driver = prefetch
}
dovecot-ldap.conf.ext has these settings (only the relevant ones)
dn = ***whatever, it works***
dnpass = ***whatever, it works***
auth_bind = no
base = dc=rhyno,dc=tech
pass_attrs = \
=user=%{ldap:uid}, \
=password=%{ldap:userPassword}, \
=userdb_home=%{ldap:homeDirectory}, \
=userdb_uid=%{ldap:uidNumber}, \
=userdb_gid=%{ldap:gidNumber}
pass_filter = (&(objectclass=postfixUser)(mailacceptinggeneralid=%n)(mailacceptinggeneralid=@%d))
so what am i missing? also, this format of setting variables
(=<output_field>=%{<whatever_special_result_field>})
is never explained
on the wiki (or am i just blind?)
thanks in advance,
a
