Implementation

#HvA project Implementation - 2015 Currently under development
This project implementation, for the University of Applied Sciences of Amsterdam

Feel free to copy/use it for your own project.
Keep in mind that it took me several days/weeks, beers and asperines to make this.
So be nice, and give me some credit, I won't bite and it won't hurt you.

Now that is said, I can explain what I've made.
First of all you need to understand the different parts of this project

• SAS: Smart Authentication Server (JAVA Servlet)
  
• APS: Authentication Provider Service (LDAP directory)
  
• ARS: Authentication Request Server (VPN server and NPS with our extension DLL)
  
• APP: The android/ios app to enable the 2nd Authentication step
  
  A simple overview if the device is not registered in our APS:
  > ARS send access request over RADIUS to NPS
  > NPS extension receive access request
  > NPS extension send authentication request to SAS
  > SAS Authenticates the user via APS, APS returns NO userinfo
  > SAS reply with code 2 (User needs device registration) and send sendmail request to APS
  > APS sends email to user
  > User follows instructions mail (Download from link and open from link)
  > User logs in with device
  > Device sends register request to SAS
  > SAS forwards device registration request to APS
  > APS registers device
  > SAS sends result code to device
  
  When a device is already registered in our APS it goes as followed: > ARS send access request over RADIUS to NPS
  > NPS extension receive access request
  > NPS extension send authentication request to SAS
  > SAS Authenticates the user via APS, APS return userInfo
  > SAS sends a PUSH notification to device
  > Device access response (approved or cancelled) is send to SAS
  > SAS replies to ARS with corresponding code
  > ARS proccesses the request (code 0= accept/ code 1=reject)
  
  You can find all the SAS error codes in the errorCode.java class
