Hiya

I need some help to configure freeradius with openldap. I have a ldap database
which stores password in SSHA format, so i choose PAP for authentication. I want to use freeradius to authenticate
on a netgear Wifi access point.

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

I've set up the AP in client freeradius in clients.conf, with a secret and shortname
like in documentation. 

Next i've put auto_header = yes in pap.conf
And uncomment the line ldap to activate module in /site-enable/default

When i start server in debug mode, authorization works fine but server have problems
to authentication step and i don't understand why
Here is the debug comments :
