Clients' Existing infra is with Aruba Controller, AP's & CPPM. Currently, CPPM is integrated with MYSQL server installed on Ubuntu. This will store the Students database, so apart from username and password, it will also store their enrolled Batch details, Roll Number, Phone Number, etc. Now is it possible to use additional fields apart from username and password for authentication? Client requirement is that when students connect to the WLAN network, he should pass through a Captive Portal, enter his Username, Password, Batch No, Roll No (these details are also visible on Access Tracker) and only if all details are correct should the student be given network access.
