[Michael Ziemann]

Hi all!

I have a problem with simultaneous login:

I already described the problem and got following solution:

  The NAS isn't sending accounting STOP messages.  Fix it.

  See also "man radzap"

  FreeRADIUS doesn't enforce Idle-Timeout, or Session-Timeout.  Only the
NAS does.

---------------------------------

The NAS is sending accounting STOP messages. I splitted raddact into 
radacct_start and radacct_stop.

In the table raddact_start, i have an entry with the ACCtStartTime time 
(2007-09-25 08:30:03), but no ACCtStopTime (0000-00-00 00:00:00).
When I disconnect, freeradius writes the ACCtStopTime to the table 
raddact_stop. So, in the table radacct_stop I have the  ACCtStartTime  
(2007-09-25 08:30:03) and the ACCtStopTime (2007-09-25 08:40:53). (The 
NAS must send a STOP message.)

The User can connect again, when I delete the entry in radacct_start 
with the ACCtStopTime (0000-00-00 00:00:00).

There are no right-problems, because the freeradius connects to the 
MySQL-DB with the User root (and of course the right pwd) with the 
rights "ALL PRIVILEGES".

Thanks for the good support (especially to Alan).
