How to check logs

I use freeradius to provide eduroam service for our university. It works 
fine. My setup is pretty basic, with just a few changes from the 
default. I am using EAP-TTLS with PAP in the inner tunnel.

Yesterday I got a complaint from a foreign user, he didn't get wifi 
service with his usual settings. I looked for the logs under radacct/ in 
the folder with the IP of the NAS. I have 'auth-detail', 'pre-proxy', 
'post-proxy' and 'reply-detail'. I was able to find logs of his packages 
in auth-detail and pre-proxy, but was unable to find out if I got any 
reply. I can link logs of packets between 'auth-detail' and 'pre-proxy', 
and also between 'post-proxy' and 'reply-detail', but I couldn't find a 
way to see which reply-detail packets correspond to any one in 
auth-detail. Is that possible? If yes, how? If not, what should I do to 
be able to track reports like that without running the server in debug mode?
