Thank you.
Once I enabled that, I got similar but not identical information.
11-29-2012 10:06:55 Local1.Info securearuba1.risd.edu Nov 29 10:06:55 CARR authmgr[1873]: <522038> <INFO> <CARR 10.2.5.41> username=mstern MAC=54:26:96:a4:a0:c2 IP=0.0.0.0 Authentication result=Authentication Successful method=802.1x server=wireauth-rad
I see message ID 522038 more often than not, versus the number you mentioned.
Is it Aruba OS dependent?
