AAA with Windows Active directory

Hello,

I just installed v5.20 , Its a fresh installed machine . All I want to setup AAA radius and authenticate my windows active directoy users with my Mikrotik machine via AAA .
I’m following this below guide.

http://wiki.mikrotik.com/wiki/AAA_with_Active_Directory

Im stuck in a command /ip ppp AAA when I try it and found no result after ip ppp shown in red sounds like some thing wrong. Can any help me how do I setup above scenario or provide step by step any other tutorial.

Looking forward for your kind response.

PPP is not a sub-menu of the IP menu.

just type ppp aaa
(leave off the ip)

Otherwise, make sure the PPP package is installed and enabled on your system in the system > packages menu.

Thanks for you prompt reply .

Kindly some one update the tutorial , here is little changes in 1st two steps .

Old:
ip ppp AAA  
   use_radius=yes
   accounting=yes

Updated:
 ppp aaa set use-radius=yes  accounting=yes 


Old:
ip ppp pptp-server
   enabled=yes
   authentication=mschap1,mschap2

Updated:
interface pptp-server server set enabled=yes authentication=mschap1,mschap2
