[Dovecot] per user quota using LDAP entries

[Kenneth Oncinian]

Hi List,

This is my first post to this list so please be gentle :-).
First of all, kudos to the developers of dovecot!

Im trying to implement quota, and I followed the instructions in the wiki.
My problem is the quota specified per user is not being honored, only the
global quota setting.
I do have an "quota = maildir:storage=204800" in the plugin area and enabled
quota in the mail_plugins for both imap and pop3.

This is my user attribute in /etc/dovecot-ldap.conf:
user_attrs = homeDirectory=home,uidNumber=uid,gidNumber=gid,mailQuota=quota
wherein the "mailQuota" attribute has an entry of "mailQuota:
maildir:storage=30720".

So i was expecting of a 300MB quota for that user, but dovecot is using the
global quota of 200MB instead of 300MB.

My dovecot version is 1.0.0
