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.

  Patch the source.

  Or, use rlm_linelog, in the "Post-Auth-Type Reject" section.
