Does the database contain information for the first user session? If not, that's the problem.
Yes.
Also check the attributes in the packets. Does it look like the user is logging in via the SAME session? i.e. Look at the two sessions. Are the attributes identical (other than EAP-Message). If so, then it looks like the user is logging into the same session, twice. Which is allowed.
The acctsessionid field is different for each session, so I think that the user has opened two distinct sections. There's no debug message saying "This is why Simultaneous-Use is going
wrong". There ARE lots of debug messages showing what it's doing, and why. You've got to read them, understand them, understand what the server is doing, and go on from there.
I know that! But how could have this line right ??? ;) I tried to completely uninstall freeradius, reinstall and configure it again. The problem still persists. The radwho command is return the message "radwho: No configuration information in radutmp section of radiusd.conf." This may be related to the problem? Best regards Renato L. Sousa
