Problem in sending PAP Authentication with radclient

Hello We have set PAP scheme to MD5 in "radius.conf". Now we can't authenticate users using "radclient". When configuration changes from 'MD5' to 'Clear text', every thing is good. What should we do if we want send password using MD5 method? If "radclient" doesn't support this, can you suggest an open source radius client which can do this? Thanks. --------------------------------- Yahoo! Photos Got holiday prints? See all the ways to get quality prints in your hands ASAP.
