How to allow users to change their login passwords

[Shivkumar]

I have the following setup:
a)freeside server:
debian sarge/testing kernel 2.4.27-1
freeside v1.5.0 pre6
HTML::Mason
apache-ssl-1.3.33+mod_perl-1.29
postgresql-7.4.7-2
b) freeRADIUS server:
debian sarge/testing kernel 2.4.27-1
freeradius-1.0.2
mysql-4.1_4.1.10a

I am able to create customers on freeside; assign usernames and 
passwords and these get into the mysql database of the radius server as 
well. now my question is:
is there a way to allow the users to change their passwords using 
freeside?  The other obvious  method would be to provide a link that 
would let run a script that would connect to the mysql database and 
change the appropriate field in the radcheck table.
i found this link (google) which provides a very cumbersome way of doing 
this:
https://www.mast.queensu.ca/doc/service.catalogue/access_control/add-user.html
( I cant imagine why they would want to provide public access to the 
freeside server!)
