Dear Community i need help, i do work with an ISP has wireless network across the country build up using more than 5000 wireless devices using Motorola/Cambium Canopy microwave radios. Currently, if a customer did not pay the subscription until the last day of the month. A agent from customer support department disconnect the customer manually by disabling SM's (subscriber Module) interface. 1.) i have been requested to come up with some kind of solution where this must happen automatically (connection/disconnection). because we have grow enough and it is actually difficult to handle this manually. if [[ disconnection]]; then customer should be redirected to a static web page, where he is told the reason of disconnection that his subscription has expired. 2.) i did research about it and came up with the solution to setup Freeradius v2.2.0. 3.) FR has been configure properly, i have tested with Cisco & Chilli NAS using MySQL Database users. AAA functionality works as expected, Max-All-Sessions, Session-Timeout etc.. etc.. etc.. WORKS !! 4.) i know Cambium AP can also act as NAS and support EAP method as well. But i am unable to understand the logic that how it can archive the above mentioned requirement - PROVISIONING SERVICE USING AAA 5.) i have also setup open-ldap servers as replication model on *CentOS 6x, UB 12.4LTS & FreeBSD Unix*, because i learnt that these are the components are the answer to our requirements. But i am not so much clear how LDAP can be used to authenticate SM's. i have little idea from my research that i can use Session-Timeout attribute so that SM needs to authenticate everyday. This is here the confusion is. i can figure out using MSSQL query from our CRM database that who has not paid. But what should happen if customer did not paid? user should be deleted from LDAP? so that SM is unable to authenticate by FR ? Am i correct that LDAP can be used in such scenario ? i know many admins are using such techniques. Thats why seeking help & their advice. if someone has little time just to help me understanding how to put components together, will very very grateful. all component has been setup but could not understand how it would work together. Thanks / RM--
