Dear List Members, i have working setup of FreeRadius 2x (freeradius-2.1.12-4.el6_3.x86_64) including "rlm_sqlcounter" (Max-Daily-Session). User are logged off alright when "Max Session Timeout" is reached. But users can re login to gain access. The username and passwords are for hotspot. We do not want the username and password to work again once it has been used. For example: prepaid voucher (MySQL username & password) has 1 hour access. User should be able to use sum of one hour, either continuously once they are logged in or in parts (30min today & 30min tomorrow so on) username & password must never work for more than 1 hour to access our network. i am bit confuse attribute to use, i would grateful if someone can advice the correct attribute to use for the purpose. Thanks
