freeradius authentication stops working after some time...

Have you read the changelog between 2.1.0 and 2.1.8?  Maybe there's a known bug?  I've had issues where some part of SAMBA dies (winbind/nmbd/smbd) and of course Auth will also fail, but if all the SAMBA pieces are working and FR is running, it usually just works!

Maybe run in debug mode until it dies and hopefully catch something interesting.

Hi List...

I've been having this strange issue, that I hope somebody in here will 
be able to assist me in solving.

I have a Linux machine (Ubuntu 9.10, 32 bit), running freeradius 2.1.0 
(ubuntu 9.10 version, but re-built with ssl), setup to provide 
authentication services for a wireless network using ntlm against a 
Windows 2008 AD.

On fresh reboot of the machine, everything works just fine. After some 
time, though, things start to fail (I'm not sure exactly how long it 
works, or even if the working period of time is the same every time, but 
I'd say roughly a days time).

Even when authentication is failing, wbinfo -t and ntlm_auth appears to 
be working and freeradius is still running. But it starts logging "Auth: 
Login incorrect:" errors.

Restarting the server makes things work again - every time.

Any idea where to look? Thanks in advance.
