Under Ubuntu 14.04.3 I have installed all of the OS updates and the following dependencies as per instructions: apache2 libapache2-mod-php5 mysql-server libnet-snmp-perl libcrypt-rijndael-perl libcrypt-hcesha-perl libcrypt-des-perl libdigest-hmac-perl libio-pty-perl libnet-telnet-perl libalgorithm-diff-perl librrds-perl php5-mysql php5-snmp php5-gd php5-mcrypt rrdtool libsocket6-perl
along with the optional libweb-simple-perl libnet-ntp-perl libnet-dns-perl and then installed NeDi v1.4p6.
Everything works as intended to work, however when I configure the gui to use radius authentication
radserver 192.168.0.1 1645 mypass 5 2
something is off.. I use a windows 2008R2 NPS box as a RADIUS server, which is tested with other devices. However, when I am trying to connect to NeDi with the above configuration parameters, I got a "server error message" in the browser. I did try a couple of them, including IE, Chrome and firefox.
From the RADIUS server side, I can't see any log in attempt in the logs.
Is there anything else that I need to install, in order to get the gui authentication to work with RADIUS?
