Adding a ldap.attrb Dialuppassword to radius-ldap.schema

["Jóhann B. Guðmundsson"]

RHEL5/FreeRadius freeradius-1.1.3-1.2.el5/Fedora Directory server.

Scenario...

Currently trying to move all our dial up user entry's from users file to 
ldap ( FDS )
and need to add an attribute in radius ldap schema which would contain 
clear text password
of the dial in password for the dial up users and match the dial in 
password to that password
instead of users login password.

What needs to be done to make this possible if it is possible?

( user are already authenticated through ldap except for their adsl 
dial  in passwords
which are in clear text  and even if the passwords weren't in clear text 
and they could
use there login password to login the user ain't smart enough and or 
technology challenge ( or at least majority of them )
to know if they change they're login password they needed to change it 
in the adsl router as well )

Schema changes?
Dictionary changes
ldap.attrmap changes
ldap changes in radiusd.conf? ( password_attribute already mapped to 
userPassword in the ldap section )

Best regards
                Johann B.
