 It's more complicated than that.  The NASes need to be deleted, too.
And this has to be done without affecting normal server operation.

 As always, patches are welcome.

Well, every given interval a query will run on the database server to get the 
list of nases and it will build a new linked list based on that and delete
the other nodes and free the pointers of those.

I guess that coming up with a method to check against each nas if it's
there or not, and to remove or add it based on a check is do-able
but would probably face some efficiency issues where-as I think it
would be proper to create a new linked list with whatever nases that
query returns and free the previous linked list from memory.

I haven't had a look at the relevant code but it seems quite basic
to implement unless I'm over-seeing some critical aspects :-)

I'll be glad to take a look if you can refer me to the current piece
of code where freeradius handles the nas lists read from the database
and stores them.
