First question: During "normal operation" (i.e. before a restart) do
you see this in the log at all? If you run "condor_status -collector"
do you see an ad for the Collector?

No, only once after restarting condor. No, there's no collector ad in the output.

For some special cases, including when a daemon sends commands to itself, it
does so using a differnt mechanism than the normal security methods. This is
why it's not using GSI or KERBEROS, and likely why you are ending up with the
unauthenticated@unmapped canonical name. However, the same authorization
policies are still being applied.

I don't know if it helps, I tried to set ALLOW_CLIENT = * (of course, it's not an acceptable policy, just out of curiousity, before it was: ALLOW_CLIENT = *@$(UID_DOMAIN)/*.$(DEFAULT_DOMAIN_NAME), then the collector ad is there, and I got this in the CollectorLog:

09/15/14 13:43:14 SECMAN: command 19 UPDATE_COLLECTOR_AD to collector X.Y.Z from UDP port 55406 (blocking, raw).

09/15/14 13:43:14 Return from HandleReq <receive_update> (handler: 0.000s, sec: 0.000s, payload: 0.000s)

The good news is in this particular case, it probably isn't really a problem
and is just noise in the log, but it is definitely something I need to look
into. Thanks for the report... I will investigate, make a ticket, and get back
to you.
