Freeradius authentication errors even after readding clients

It would probably be good to say that the default path for reading clients has been changed.
The Changelog just tells to readd the clients.

Maybe it would be helpful to update the Wiki too.

New path for clients should be:
/etc/freeradius/3.0/clients.conf

Before it worked with /etc/freeradius/clients.conf .

Because of that there are many dpkg-bak and dpkg-new files within /etc/freeradius .
