... which sometimes is as simple as changing the database schema to
use (username,acctuniqid) as unique key. When you do that and a
duplicate accounting start packet arrives, the default
accounting_start_query (insert) on dialup.conf should fail and
accounting_start_query_alt (update) will be executed instead. So you
won't have duplicate records.
