Go into RadiusNT Admin.
Click on ODBC Options.
Make sure that "Concurrency Control" and "Variable Login Limits" are both
Make sure that all of your users have a login limit set to at least 1. You
can run the following SQL command to set them all if need be:
set loginlimit = 1
where loginlimit < 1
Now you can go into Emerald and allow whatever subaccounts you want, to have
different login limits. One username may have it set to 1 (our default),
and another user may be set to 3 or something, to allow 3 concurrent logins.
