I tried to use for login authentication using the userman, but does not work, I repeated the steps in the wiki. my current version is 6.22

I've also tested in version 6.17, 6.18, 6.19, 6.20 any work.

Have you set up a router (first button on the left) in user manager?

I also had trouble with the wiki - I think it may be a bit dated now.

Settings for user manager, hotspot and radius must correspond to use radius authentication.
