Using mschap authentication without EAP

Hi, i'm using freeradius-1.1.2 with openldap for storing users account, for authenticate a WI-FI LAN. I need of a transparent authentication method since for the clients are heterogeneous so i can't use any type of EAP* authentication because I cannot install Xsupplicant on every Client. Can I use mschap authentication for this and there are some specific documentation ?,i've searched a lot but i haven't found exhaustive documentation. And if I cannot use mschap, are there others solution for wi-fi authentication via LDAP? Excuse my bad english. Giusy Venezia
