[Dovecot] Per User Quotas with LDAP on Dovecot 1.x

7 Oct 2010


      Alle,
We're running Dovecot V1.0.7 on RHEL5.5, using maildir. We would like
to user per user quotas with an OpenLDAP (V2.3.43) backend.
We have setup a default quota in /etc/dovecot.conf:
quota = maildir:storage=10240:ignore=Trash
And have the following userdb configs in /etc/doveconf.conf:
userdb ldap {
args = /etc/dovecot-ldap.conf
}
and the following user_attrs defined in /etc/dovecot-ldap.conf
user_attrs =
uidNumber=uid,gidNumber=gid,mailQuotaSize=quota=maildir:ignore=Trash:storage,mail_plugins
The user's quota setting is:
dn: uid=loadtest,ou=people,dc=subaru,dc=nao,dc=ac,dc=jp
mailQuotaSize: 1024000
Dovecot-imap appear to recognize the quota from ldap, as the
Thunderbird quota plugin reads the correct info from LDAP if the
mailQuotaSize entry exists, and the default storage=10240 from
doveconf.conf if there is no LDAP attr.
However, deliver bounces the mails with a quota exceeded message:
deliver(loadtest): Sep 28 10:46:23 Info:
msgid=20100928204620.B83876402EA@loa.subaru.nao.ac.jp
: save failed to INBOX: Quota exceeded
deliver(loadtest): Sep 28 10:46:23 Info:
msgid=20100928204620.B83876402EA@loa.subaru.nao.ac.jp
: Rejected: Quota exceeded
Are we misunderstanding the way quotas are supposed to work in 1.x, or
are we just missing something, period? Any help would be appreciated.
Best Regards,
Camron
