cyrus autorization identifier trick

[Nestor A. Diaz]

Hello cyrus people.

Following your cyrus recomendations for a 15K users mailstore, i have a 
new requeriment, we will like some administrators to login to any 
mailbox in order to check the successfull delivery of some emails, 
without having to login into each account with the associated login and 
password, i explain:

i use cyrus virtual domains system,a user log in using this user id and 
password:

user at domain.com
userpassword

but i will like to make some trick for a user to login into a mailbox, 
using the followin schema:

user:admin at domain.com
adminpassword

the idea is that based on username (user:admin), the system notice that 
the user login is 'admin' and that he wants to see 'user' mailbox.

is something like this possible ? i have read something related under 
http://www.lichteblau.com/ldapvi/cyrus-sasl/sysadmin.html but i still 
don't see the way to do this, because auxprop pluing only returns the 
password asociated with an account, but how can i make cyrus to know 
that 'user:admin' refers to 'user' mailbox ?

Thanks.
