How can the verbosity of logging be increased for SASL authentication failures? To be more precise, to include the failing user name in a log file on Mac OS X 10.7 (Lion) Server?
Linux hosts have logging like:
Oct 1 18:36:56 megatron postfix/smtpd: warning: unknown[18.104.22.168]: SASL LOGIN authentication failed: generic failure Oct 1 18:37:02 megatron saslauthd: do_auth : auth failure: [user=academia] [service=smtp] [realm=www.MyServerDomain.com] [mech=shadow] [reason=Unknown]
Where Mac OS X Lion (10.7) Server it's logging granularity is no deeper than:
Apr 2 16:43:41 nl3 postfix/smtpd: warning: unknown[22.214.171.124]: SASL LOGIN authentication failed
How can the user name be logged too?
Help on how
/usr/sbin/saslauthd is invoked by postfix/smtpd is also welcome and/or where its configuration is stored.
