I just upgraded from 18.04 to 20.04 on my workstation. It uses LDAP authentication. I already have an authenticated user. It used to be shown in GDM prior the upgrade. However after the upgrade only an admin account is shown.
I’m able to type in my username and password and can login. How can I make my user reappear in GDM? (I don’t want to change GDM to lightDM)
