mysql freeradius "rlm_pap: empty password supplied"

[serre]

Hello,

After some hours of googling my problem, i come. I hope somebody will be 
able to help me!
I set up a mac based authentication, with users in mysql database. It is 
working properly when users are difined in the users file, but did not 
work with empty Cleartext-Password in the database.

Any idea? It is the only problem I've found when following this EXELLENT 
howto page:
http://wiki.freeradius.org/SQL_HOWTO

Thanks in advance





I show you to of my test users, one with password, the other without 
(hope i'm clear):
