Hi list,
just to share my solution. Now I've both TTLS+PAP+LDAP and 
PEAP+MSCHAP+LDAP work.

My LDAP server lives on CommunigatePro, and store password in various 
mode. This is not a problem for bind operation (TTLS+PAP), but have 
to be configured specifically for ldap search, method used by 
PEAP+MSCHAP.

So problem didn't live in Freeradius.

Regards,
Paolo.
