expiration

I am trying to set an expiration date for daily cards where tha expiration date is inserted into the database with a postauth query. I am not sure how to add this to my radiusd.conf file (1.0.4) I am guessing that I need a key, counter-name and check-name. right now I have: expiration { reply-message = "Your account has expired, %{User-Name}\r\n" } Also, do I need to add "expiration" to instantiate? Thanks for any input, Carl Peterson
