[RADIATOR] Reject empty username?

[Robert Blayzor]

We have a radiator process that just runs to collect accounting records.

We have a single <AuthBy> (SQL) to store these records.

We're getting some clients that are just sending an empty (or no)
username attribute. Our database requires a non-null username. Rather
than just pump them into the database with some bunk username like
"NULL" or "none".... How can we silently ignore these accounting records
while sending a ACK back to the NAS so it doesn't keep sending them?


Ex:

<AuthBy SQL>
   Identifier      PG_ACCT
   DBSource        dbi:Pg:dbname=..
   DBUsername      x
   DBAuth          x
   Timeout         5
   #FailureBackoffTime      10
   NoDefault
   AuthSelect
   AccountingTable accounting
   #AccountingTable accounting_%Y%m
   AcctColumnDef   ts,%J,formatted
   AcctColumnDef   sess_id,Acct-Session-Id
   AcctColumnDef   rtype,Acct-Status-Type
   AcctColumnDef   userid,%U,formatted
...

</AuthBy>
