I am using an OC200 on a network in a campground with about 250 camp sites.  Each site is set up with its own local user account with a login and password, and each account allows up to 6 devices connected.  Since this is a seasonal campground, each account is set to expire at the end of the season.  All went well on the first season.  At the beginning of this season, I went through each account and extended the expiration to the end of this current season, but now the client devices that log back on show up as pending and won't work until I manually authorize them, and extend the expiration date for each of their devices.  It appears that this is mostly affecting devices other than phones, since I believe people are able to log out, or forget the network and log back in easier than on other devices.  First question, is this what is happening? Second question, is there a way, at the end of the season, to automatically remove the expired client devices so that when they next try to connect it forces them to log back in?
