Script: What is the database structure

I am trying to use a Radius Server for MT login. the problem having MT connect and check user accounts on the database on my Raduis server. I need the to know which structure my databse should have for MT to be able to get record from it.

database? RADIUS uses a standard system, your RADIUS is not supposed to have a specific structure. Just tell RouterOS to use a remote RADIUS for authentication and that’s all

Please I need to know how to creat the users in the radius server. Ii mean the usernames and passwords and expiredate and others. Please I need help

we cannot help you configure a RADIUS server, this topic is not related to mikrotik. i suggest you to read it’s manual.
