A popup on login, asking to reset password. So, I put a new one in and it wasn't acceptable ("check with your server admin"), so I picked another one. I am the sole user with admin privs, there's an inactive guest account that I setup and haven't used for years, and Filevault has been enabled for 4 years. Computer is set to ask for password after 5 mins of screensaver.
I can't even see where the "server admin" would be able to adjust password requirements.
