Is there a (relatively easy) way to determine what is causing a user
account to be locked out? The admin account on our 'primary' ipa host is
locked out frequently, but somewhat randomly; sometimes it will be less
than 5 minutes it is available, and other times several hours.
ipa user-status admin will show something like:
Failed logins: 6
Last successful authentication: 20160516214142Z
Last failed authentication: 20160516224718Z
Time now: 2016-05-16T22:52:00Z
ipa user-unlock admin does unlock it.
But parsing through the various logs on the affected host doesn't give
me what I need to know, primarily, which host(s) are trying to access
admin and causing it to lock.

I think you'd need to poke around in the KDC and 389-ds access log to
find the auth attempts. I guess I'd look for PREAUTH_FAILED in
/var/log/krb5kdc.log and look for err=49 in the 389-ds logs and then
correlate the conn value with a BIND to see who was authenticating.
