We are using Fredora Directory server 7.1 for authentication of users, mail accounts and proxy authentication. Yesterday I have observed that passwords goes in plain-text and anyone can retrieve actual user name and  password  easily with using a  software named cain. 

Can anybody suggest how can i secure user's password so that the password should travel in encrypted form.

I am new with fedora-ds so please explain me in detail.
