Do you have an entry for mupdate in your /etc/services file ?

It should be like :
mupdate         3905/tcp

Separate your frontend, backend and mupdate server, on differents  
servers or, if you really can't,
with different conf and db files and differents ports or ip.

You then can have your frontend and backend authentify to mupdate with  
sasldb and your user authentify to the frontend as you want.

Before going tu murder, have a look to replication.
