My server has a RADIUS functionality. I want to know where does it log about successful and rejected log-in events and other related info? I have to track RADIUS behavior so that's why it is important to know it.

Since you tagged this as debian, i suppose it has freeradius installed.

The default configuration puts all logs in /var/log/freeradius. You can find successfull/failed login attemps in /var/log/freeradius/radius.log, and accounting information in /var/log/freeradius/radacct/*.

+1: Thanks for rapid answer. Follow up question: are there another RADIUS possibilities than freeradius? I still don't know which version that server has (no access yet) and would like to collect all the possibilities beforehand. – Mikko Setälä Jun 14 '11 at 9:55
On debian, an aptitude search radius shows at least radiusd-livingston, xtradius, yardradius as radius servers. But nothing prevents you to compile one of the many others (try a search for radius server software on google). But chances are it really has FreeRADIUS installed (The world's most popular RADIUS Server as stated on the site). – Mr Shunz Jun 14 '11 at 10:03
