Allow more control over concurrent logins
Currently there is a checkbox that allows concurrent logins, or not. I'd like to be able to replace that binary checkbox with a number like this: "Maximum number of concurrent logins "
So we could set the value to 3, and then the fourth login attempt of a username would log out the oldest login.
I'm not familiar enough with the CP database to try this myself, but it would be a nice feature to have. Currently we enforce concurrencies on the RADIUS server, but this is problematic in the even of power failures or other unexpected outages, where the server and NAS get out of sync.
