Client Authentication

[Sanmaxx777]

Hi, How can I perform client authentication on DHCP server? In rfc3118 option 90 is added for client authentication. but in lib/options.js option 90 is not configured. I also tried to add same in options.js but whenever I add username and password with simple PWD mode my server doesn't listen to that request or some this wrong with my client conficuration. I am using Cantos 7.8 for both my server and client.
