rlm_sqlcounter and something else than Session-Timeout

[Seferovic Edvin]

OK, now I've understood that it's a NAS "problem". ( Maybe my bad knowledge
of english language is guilty for that - sorry ). 

Lewis suggested that I sponsor your project... well I would if I really
needed this feature so badly ;) and since I am just only a student, I might
try hacking the freeradius code.

In my scenario, I use Poptop and RP-PPPoE server as NAS ( by the way ). 

Alan should I write a patch for 1.0.5 or should I wait for 1.1.0, or just
take the daily from CVS?

Regards,

Edvin Seferovic

  As I was trying to say that in general, you CANNOT do this.  You can
check if they're over the limit at the START of a session.  The NAS
will *not* check the limit during a session, and the server can't
check the limit during a session.

  So if they're under the limit at the start of the session, they can
go over during the session, and no one will notice.  This has NOTHING
to do with changing the limits during a session.

  If the NAS supports this, it may work.  But 99.9999% of the NASes do
NOT support this.  It's not a standard, and it's not a common vendor
extension to RADIUS.

  I can't test that, sorry.  I'd rather see a patch that works.
