[Dovecot] Lda does not query pgsql

[Tognini Samuele]

Hi,
I don't know if it's a bug or my configuration fault, but LDA does not 
work as i expect.
Dovecot auth connects to a pgsql database that mirrors Nis users infos, 
but it has also quota settings  because i'd like to use a per-user quota 
environment.
Mailserver and Postfix authenticates users with Nis (through PAM), while 
imap and local delivery (with the postfix  mailbox_command setting) are 
left to dovecot mechanism.
Imap works perfectly,  dovecot retrieves authentication and quota 
setting from database, but dovecot LDA seems to not query any database 
(and nothing is logged) , so that quota is not retrived and message is 
not bounced when user is overquota.

You can see it in the verbose log:

deliver(tognini): 2007-02-08 12:25:02 Info: Loading modules from directory: /usr/lib/dovecot/modules/lda
deliver(tognini): 2007-02-08 12:25:02 Info: Module loaded: /usr/lib/dovecot/modules/lda/lib10_quota_plugin.so
deliver(tognini): 2007-02-08 12:25:02 Info: Module loaded: /usr/lib/dovecot/modules/lda/lib90_cmusieve_plugin.
so
deliver(tognini): 2007-02-08 12:25:02 Info: mbox: data=/home/t/tognini:INBOX=/var/spool/mail/tognini
deliver(tognini): 2007-02-08 12:25:02 Info: mbox: root=/home/t/tognini, index=/home/t/tognini, inbox=/var/spool/mail/tognini

If i set quota variable in dovecot.conf, still no query but the global 
variable is used for all users:

...
deliver(tognini): 2007-02-07 12:33:04 Info: dirsize quota limit = 1024kB
...
