Login keychain on MacBook Air is empty
Whenever I cold boot my MacBook Air running macOS 10.12.3 and login with my Standard User account (non-administrator), I'm prompted to enter my iCloud login password. I then go through the new user setup.
Then I get a message "This Mac can't connect to iCloud because of a problem with..." and there's a button for iCloud Preferences. I go to iCloud Preferences and I'm prompted for my iCloud password. This also happens with every login.
(NOTE: The account name has been removed from the message by me).
I opened Keychain Access and found my Login Keychain completely empty.
I don't have this issue with any other accounts on the machine, Standard or Administrator, using the same iCloud account.
MacBook Air (13-inch Mid 2012), macOS Sierra (10.12.3)
