Hello George, I think that you should take a look at this: http://deployingradius.com/documents/protocols/compatibility.html . It is probably the best guide that you can use. Note the CHAP section.

Users credentials are stored encrypted in LDAP database. Unfortunately CHAP requires only cleartext password. I dont want to store users credentials plain-text. Is there a solution about it?
