Mikrotik & Radius

Hello all,

I’m trying to implement radius on my MT and I didn’t find any way to separate my users in differents groups.
I want to have group for ppp, dhcp,hotspot,winbox… and put my users in the rights groups

user1 : ppp
user2 : winbox & ppp
user3: ppp & hotspot

Any ideas, or samples how can i do that ?

Is it possible to achieve this goal with usermanager ?

Thanks for your help.
