That is very frequent. Every 15-30 minutes is more usual. You run the 
risk of overloading your database.

You can only reject an authentication request, you can't reject in 

The way to do this is to send a CoA disconnect request to your NAS to 
kick the session, if it's supported. If not you will need to either use 
some other method to terminate the session, or use shorter session 
lengths and then refuse on next authentication.
