(RADIATOR) "Phantom" attribute

Tue Apr 18 17:55:11 CDT 2006

Hello all

We´re getting an error message in an instance that handles RadSec
traffic. It references an invalid value for an attribute not present
in the incoming packet. This is a trace 5 showing the problem (BTW,
code for trace 5 is missing in ServerRADSEC.pm, we borrowed it from
Radius.pm for this test):

Tue Apr 18 18:55:45 2006: DEBUG: Handling request with Handler
'Acct-Status-Type=Stop'
Tue Apr 18 18:55:45 2006: ERR: There is no value named  for attribute
Ascend-Disconnect-Cause. Using 0.

You'll note that it is referencing an absent Ascend-Disconnect-Cause
attribute. Also, I think I'm seeing two spaces between 'named' and
'for' in the error text, suggesting to me an empty string in that
place.

best regards
cl.
