- CentOS 7.5.1804
- GDM, LightDM, SDDM tested
- yum group "KDE Plasma Workspaces" as desktop environment, GNOME also tested
- LDAP logins provided by sssd, /home/* mounted via autofs over NFS
Login as the root user works, as well as any other local user. Bypassing the login screen by switching to TTY2, logging into an ldap user via the terminal, and doing startx also works, but logins from the display manager itself pause for a half second and then bounce back to the display manager.
