It may have been host locking. I'm trying to provoke user-locking,
and I'm not having much success.

My pam_abl.conf has a user setting of 3 failures in 10 minutes
to cause locking. Host locking is after 10/hour

After 3 failures, I can still log into the same account, george at localhost
The  tracing below is after 4 failed logins.
