We have a number of systems on the internet. They are constantly attacked through ssh. A lot of attacks try to guess passwords for a user called “admin.” It’s a high enough volume that our admin is always locked. When I need to do something as admin I have to disable attack lockout temporarily. Fortunately that’s uncommon, since we normally use users in the admins group rather than the actual admin user.

Well ok, further observation.
Not much to see in krb5kdc.log, just same 'revoked credentials' for admin
However
When looking at ipa user-status admin after ipa user-unlock admin, i can see the Failed logins are increasing to 6 whithin 5-10 seconds. Same happening on both masters, ipa user-unlock admin, then 1,2..6 failed logins within few seconds.
something probes login as admin? You should have in krb5kdc.log an indication of the client IP address. Where that points to?
