Hi Alan,

just another confirm to check if I understood correctly:

So now because of the misconfiguration of the NAS I have IPs in the 
radippool table assigned to users not existing anymore in the radius 
tables (users that ceased the service) with expiry_time in the past.

If I update those users NAS and add the interim-update, should those 
record be cleared?

And, speaking of expiry_time: what is in that case the best pratice, 
together with the 10 minutes interim-time? One hour (the default value) 
would be fine? Thanks!
