Re: [Freeipa-users] How to determine cause/source of user lockout?
If it's the admin account, there would be a pretty good likelihood of bruteforce attempts if your server is on the internet. One option is to rename it to something else.

[Freeipa-users] How to determine cause/source of user lockout?
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.
