If you're talking about authenticating 30 WAPs to the same basic
database of users, then you might want to consider 802.1x or
RADIUS(a.k.a. AAA). This would provide a beefy authentication that
would depend on a central server. You'd only have to change it one
place one time. I'm pretty sure DD-WRT can do that as I've messed
around with it but I don't know how OpenWRT might differ. I know both
support something called chillispot which is basically these
technologies brought together in the same way that a typical coffee
shop or hotel might do it. It is an open source solution to wireless
device/user authentication. http://en.wikipedia.org/wiki/ChilliSpot
