(RADIATOR) radiators duplicate detection (ClientIP+Identifier+?SourcePort?)

Hi!

I've seen that radiator detects duplicate records depending only on the
identifier and the client IP:

"If more than 1 Radius request from this Client with the same Radius
Identifier are
received within DupInterval seconds, the 2nd and subsequent are ignored."

Shouldn't be the Identifier, the ClientIP and the SourcePort the keys for
duplicates?

The RFC 2865 says:

"Identifier: The Identifier field is one octet, and aids in matching
requests and replies. The RADIUS server can detect a duplicate request if it
has the same client source IP address and source UDP port and Identifier
within a short span of time."


Is it a mistake in the refmanual?

Regards,
Rainer
