You were kindly given the answer previously by Maurice. But just to 
reinforce please review the compatibility information here:

http://deployingradius.com/documents/protocols/compatibility.html

The client is sending mschap, look at the table above, what are the 
valid password formats for mschap? What authentication mechanisms are 
valid with SSHA?

So you basically have 3 choices:

1) Store cleartext passwords in ldap

2) Store nt hash in ldap

3) Don't support mschap clients

Or if AD is available as your ldap use ntlm_auth with AD to support mschap.
