ok, I tried to follow your advice but I do not think I've followed the right path
I created a new virtual_server named 'test' for client localhost in clients.conf file.
In sites-enebled directory, i created a new file named test that include server test { ... .... }, but the results is the same error.
I received an access-accept by the mschap module but in post-auth the ldap module give me the same error.
At this point i will wait the new release for freeradius. 
FR2 works very very fine but it doesn't include the passchange module that i need in my 802.1x network infrastructure.
Approximately, you know when you distribute a new version of freeradius?
one week or some months? ;)

Thank you very much for your support.
