    I agree with your explanation :). But it's a problem.

   I tried deleting using, but it doesn't work as gdbm
does not allow more than one writer to that file.

   I guess I need to patch up freeradius where a delete user message
(my own defnied) is sent to freeradius from NAS. On recieveing this
freeradius would just go and delete the users mentioned in that
message. I would be introducing a new listener for that purpose.
will that be ok ?

  I have other option of shutting down freeradius and then delete
users using, but that would lead to unavailability of
service for some time.
