Can't login with a Mac user but I can manage system preferences with that account

Question

I came to office and started my Mac. The admin user (tolga) I use everyday was not in the login screen list.

Here's what I tried:

1. I logged in with my other (non-admin) account. Opened Settings > Users & Groups.

2. I opened Login Options with my admin account (tolga), strangely it accepted the password to modify settings.

3. I changed setting to display name and password, tried to login from login screen with tolga, still couldn't login.

4. My login account (tolga) is there. It says (Admin, Mobile) - I don't know what mobile means. Unlike other admin accounts, I can't change password of tolga either. ()

5. I checked Security & Privacy > Filevault, it's off

I can see /Users/Tolga

More: Previous week I installed Munki from Github. It's the first time I restarted for a week. Would the problem be related with this?

What's my chance to login with tolga account again? Thank you.

Answer 1

I found an answer.

on Settings > Users & Groups I checked Allow network users to log in at login window than I was able to login. Not a good solution, but I can access my account for now.
