Topic: Just thougt about to disable roaming in Radius or chispot conf

Hi,
we are running a few hotspots, and we have in our radius database differen Users, which are able to print tickets.
We have
user1
user2
user3 and so on.
Al these users have different passwords.

Every user can print tickets, and all the tickets work on every chillispot access point, because they are roaming.
I am wondering about if it is possible, that for example the tickets, which are made by user1 would "only" work with access point (wrt54gl) number 1, and so on.
We still want to use on all the wrt54 the same chillispot firmware!

I hope there would be a way in the radius configuration to set this up.
We already tried to set up a few radius server in parallel. This also woks fine, but it is to much work!

Does anybody got an idea if such configuration could be possible???

Thanks for your answears
