I can confirm that this is the case.  With imtest, I logged in as proxy
auth, admin user and can't SELECT user/mailbox.  When I log in with the
admin credentials, I can. 

What I need to do is merging user's account.  For that, I wanted to :

1. login on a frontend as mailadmin;

2. SELECT source mailbox

3. LIST submailbox

4. CREATE submailbox in destination mailbox

5. SEARCH messages

6. COPY messages to destination mailbox

Could you suggest a workaround, or some other way to achieve similar
result ?

I am running 2.1.13. in another Murder, and it work there (proxy
authcid, admin authzid, SELECT user/mailbox).  So I suppose that this
change somewhere in 2.1.14 or 2.1.15 ?

Thanks for your nsights, I'll be looking at the source.
