Usermanager issues

hi

i have two sites all with rb1000. i want to have one central usermanager such that client on router A hotspot will authenticate on router B user manager.

all sites are in two different locations getting internet from satellite.

i have checked this manual but didn’t quite get it.

all you need to do is to forward all authentication of clients to the router where the authentication will be done.
