hi (especially to you, Aki),<br>
<br>
so to solve the previous UID issue, i went the full LMTP route.
however, <br>
i seem to be having problems with the prefetch userdb (i'm trying
to <br>
minimize load on the LDAP server). namely, the log says:<br>

(the above is a transcript of a full session i've done over
telneting to <br>

<br>
so, i've tested the actual login process, and it works flawlessly,
and <br>
it looks like IMAP is up and running:<br>

so what am i missing? also, this format of setting variables <br>

is never explained <br>
on the wiki (or am i just blind?)<br>
