dovecot - Aug 2010 - dovecot 1.2 and quota_rules from AD

Hi

I?m trying to figure how to proper configure postfix+dovecot to enforce 
quotas from a AD (ldap). I?m using the following configuration:

dovecot.conf:

...
protocol lda {
	mail_plugins = quota
..
}

auth default {

  passdb ldap {
    args = /etc/dovecot/dovecot-ldap-pass.conf
  }
  userdb ldap {
    args = /etc/dovecot/dovecot-ldap.conf
  }
...
}

plugin {
    quota = maildir:User quota
    #quota_rule = *:storage=2M    // tried with and without this line
}

dovecot-ldap.conf:
...
user_attrs = sAMAccountName=mail=maildir:/var/vmail/%$/Maildir, 
quotaMail=quota_rule=*:storage=%$
user_filter = (&(objectClass=person)(|(mail=%u)(sAMAccountName=%u)))

pass_attrs = sAMAaccountName=user,userPassword=password
pass_filter = (&(objectClass=person)(sAMAaccountName=%u))


Quotas are set by the quotaMail in AD. And here is the log:

There?s no quota_rule in logs... uncomenting the line  quota_rule = 
*:storage=2M I got quota, bu only this static one, and not per-user. 
What I?m doing wrong?

Btw... with static configuration the maildirsize file is created, but 
without static configuration it?s not (well.. no quota_rule...).

thanks in advance,

If you always override it in userdb, it doesn't matter if you have it or
not.

Not related to your problem, but I'd change that to:

user_attrs = sAMAccountName=home=/var/vmail/%$

and then in dovecot.conf use:
mail_location = maildir:~/Maildir

because http://wiki.dovecot.org/VirtualUsers/Home

Looks ok.

Dovecot requests sAMAccountName and quotaMail fields from LDAP.

But LDAP returns only sAMAccountName, not quotaMail field. So either
that field doesn't exist in LDAP or it doesn't exist for this user or
the DN you use to access LDAP doesn't have permissions to it. Or
something else, in any case the problem isn't with Dovecot
configuration.
