Simultaneous-Use unreliable for 'other' NAS-type

[Taymour Gabr]

Hi,

Thanks Alan,

I'm confused however how checkrad can help with any simultaneous use
that isn't set to exactly '1'.
checkrad has this notice at the top
# Returns:	0 = no duplicate, 1 = duplicate, >1 = error.

So if checkrad is called when radwho would deny the user, and my
simultaneous-use is set to 3. I would want it to return 0  if that
user is logged in less than 3 times.
That in turn means, I have to hard-code checkrad to include a method
for my it for my nas to return 0, if it finds less than 3 users. The
number 3 would be hard-coded.

This doesn't seem right. Am I missing something?

Thanks again for the help

Kind Regards,
Taymour
