Logging only auth failures?

[Ian Ehrenwald]

Hi Alan
Thanks for the quick reply.  I believe I've accomplished what I wanted to do.  I've set 'auth' to undefined in the log{} section of radiusd.conf, created another instance of the linelog module called linelog_REJECT in which I set the reference to "%{reply:Packet-Type}", and then added 'linelog_REJECT' to the 'Post-Auth-Type REJECT' section within the default site config file.  My remote syslog server is now only receiving 'Rejected access: someLoginName' messages.  Thank you for your help.

I want to log only auth failures, not successful logins.  Is there an easy way to do this?  I don't want to use a SQL backing store for this project since that is what is holding the syslog data on the remote machine anyway.  'auth = yes' logs everything, 'auth = no' logs nothing, and I don't want to see/store the good/bad passwords, so 'auth_badpass' and 'auth_goodpass' aren't an option.  I'm sure I'm not the only person who has wanted to do this, but I can't find anything on the freeradius-users list.  Any help?  Thanks.
