A very simple RADIUS server built on node.js which provides two-factor-authentication with Active Directory and SMS text message
Configure LDAP in adconfig.js (example file included) and set up API URL for sending SMS (i'm using Message API by Highside)
npm install && npm start
This simple RADIUS server provides 2FA for devices and software with RADIUS support. When a user tries to logon it checks the user and his password in Active Directory (via LDAP) and, if verified, sends a SMS text message with a OTP Token to his phonenumber (which must be available from AD). Meanwhile it sends an Access-Challenge to the RADIUS client which means the client needs to ask the user for a password a second time. This time the server checks the OTP Token. If correct, it sends an Access-Accept to the client, if incorrect, it sends an Access-Reject.

This has only been tested with Citrix NetScaler 11 so far. Feel free to test this with other appliances/software and give me some feedback.
