Plain text password between frontend and backend

[Ramya Krishnan]

Hii,
I would like to configure a backend server and a frontend server(with 
mupdate server). I use LDAP authentication(SASLAUTHD) in both backend 
and frontend servers.
I am able to authenticate directly to the backend and select inbox. 
When  I connect through the frontend, I am able to authenticate but not 
select inbox. It throws an error
    "couldn't authenticate to backend server: no mechanism available"--log.
    "a2 NO Server(s) unavailable to complete operation"--command line
I want to send a plain text password as the network between the frontend 
and backend server is safe. I am trying this in cyrus-imapd-2.2.12. 
Would this not be supported in this version? If it does support, is 
there any configuration that has to be done..?

The frontend connects to the backend sees capability.

MUPDATE=mupdate://10.1.21.11/ X-NETSCAPE

Any pointers???
