I have a problem with a freeradius + samba and ntlm authetication.
the configuration work very well and without problems for a random
period of time, but after 2, 4, 7 days, the freeradius stop to work
and only work again if I restart the service (/etc/init.d/freeradius

in the same machine, I have a samba file server (connected to a
domain) and winbindd service... both still working without problems.

I have this packages installed
