I'm using IMAP::Admin here for quota-related activities.  However, my 
scripts first determine which backend the mailbox is on.  Then they 
connect directly to the backend.  That may be why I'm not seeing the 
problem you describe.  I'm using Cyrus 2.3.14 here, with referrals 
disabled.  This is what I see when running cyradm on a frontend:

cyrus-fe1:/etc# cyradm --user cyrus localhost
Password:
localhost> lq user.morgan
Password:
  STORAGE 185512/256000 (72.465625%)
localhost>


It appears that it is following a referral to the backend, because it 
prompts me for the password again.
