freeradius authentication stops working after some time...

[Casartello, Thomas]

Has anyone else seen a problem with this? This is starting to happen more
commonly with me. I'm having to reboot the server that Freeradius runs on to
get the authentication working again. I'm using AD auth through
Winbind....Here is the debug...

Machine authentication is properly configured. When I reboot it, this same
authentication is successful. The strange thing is is that a reboot is
necessary. Just restarting radius, winbind, and smbd doesn't cut it......

I run 2.1.8, server 2008 R2  and samba 3.5.2. It's something to do with
winbind, but I have not nailed it down on my installation yet.
