Generally speaking, it will suffice to create one DEFAULT entry in
your raddb/users and specify appropriate Auth-Type there, e.g.

DEFAULT Auth-Type = SQL
        Service-Type = Framed-User

The exception is:

"Internal database" means raddb/users itself. If you wish to use this
method, you will have to create a new raddb/users entry for each new
user. Clearly, this is not acceptable when you have lots of users.

If you wish to use some plaintext user/password database, you
may set Auth-Type = PAM and use one of pam modules that provide such
functionality.

You should modify file raddb/sqlserver. See

for details.
