external radius and shared users

Hello, i have a linux server with freeradius and ldap auth. The authentication is ok but i would set shared users parameter for all user. Is possible in mikrotik?

Thanks

Set the default user profile to the value you desire on each Mikrotik. I believe um-named profiles will use “default”.

Other than that, use wireshark and capture the database requests to see which data dictionary pairs you need.
