A question about rlm modules

["Ali Majdzadeh" <ali.majdzadeh@gmail.com>]

Hello all
I have written an rlm_module. It works fine. Here, we have clients
which should be authenticated using CHAP passwords. In the
radiusd.conf, I have mentioned my module before the CHAP module in the
authentication section. Also, I have found that my module should
populate the request->config_items field of the request with the
clear text password so that the CHAP module can process the request. I
have added the required code to do so, but the CHAP module complains
about the size of the password.
I want to know, is there something that I have missed? By the way, is the concept right at all?
Thanks in advance.

Regards
