[Dovecot] quota - dict permission denied

when I enabled quota plugin the following error occured :

net_connect_unix(/usr/local/var/run/dovecot/dict-server) failed: Permission denied Any ideas? My config are as follows : .. dict { #quota = mysql:/etc/dovecot-dict-quota.conf quotadict = mysql:/usr/local/etc/dovecot-dict-quota.conf } .. quota = dict:storage=81920:messages=5000 proxy::quotadict

/usr/local/etc/dovecot-dict-quota.conf: connect = host=xxxxx dbname=xxxxx user=xxxxx password=xxxxx table = quota select_field = current where_field = path username_field = username

I can connect to the database thru mysql prompt. dovecot version 1.0 rc5
