Andrew Just to update the solution for us in the end... We couldn't get auth to work on port 389, but in the end we managed to get the maxStorage field to be presented via the query on port 3268. What we needed to do was to ensure that it was added as an attribute to the Global Catalog on our Windows Servers. We could then get this entry back via our query. There's instructions on how to do this on the following page: http://technet.microsoft.com/en-us/library/cc737521(v=ws.10).aspx Thanks for the help. Regards, Andrew

Thanks, Andrew Show your full dovecot-ldap.conf file, also what port do you using ? maybe you met restriction of ldap port 3268?(http://wiki2.dovecot.org/AuthDatabase/LDAP) And show exact result of ldapsearch tool, binding under user from dovecot-ldap.conf + debug for this user when it trying to login and 'doveadm -D quota get -u $user' for this one. Also ensure that your search query returns only 1 result. We are using dovecot 2.0.19 now, but all versions of dovecot 2.0 branch was there in the past. I'm updating server since version 2.0.1 - no problem found.
