How do I add a user in Linux Radius?

[bperrotta]

I am knew to Linux administration.
I was shown once how to add users to users.db
in /etc/raddb/users.db in Linux I think with the vi editor.
Now I can't remember how. It is really frustrating, because I just started working for an isp and need to remove two dial-up users. Most Forums suck and give me loads of info i don't want instead of simply explaining how to add or remove users step by step. i don't want to know just the path to the file.
For crying out load, Will somebody just explain step-by-step?
what is the command? vi /etc/raddb.users.db and then edit?
All i see when i do this is a blank file. Sombody Anybody Please Help!

You apparently need the user added to a group in the linux sever first
using some [roo]$adduser variation.

Thats about all I know on this sorry

That's useless but thanks for trying.
This companys been around for years the groups and other users have already been created. All i need to know is how to edit the uses.db file or add or remove users. Plain and simple. Please does anbody know the answer???
