Description of problem:

Auto login of user with TimedLogin options of gdm does not work after upgrade from RHEL7.1 to RHEL7.2
Problem is observed when dconf key /org/gnome/login-screen/disable-user-list is set to true

Version-Release number of selected component (if applicable):

Red Hat Enterprise Linux 7.2
gdm-3.14.2-12.el7.x86_64


How reproducible:
Always

Steps to Reproduce:

1. Add below entries in /etc/gdm/custom.conf file for auto login of user.

[daemon]
TimedLoginEnable=true
TimedLogin=USERNAME
TimedLoginDelay=10

2. Disable user list to configure banner message on gdm login screen.

# cat /etc/dconf/db/gdm.d/01-custom-gdm-settings
[org/gnome/login-screen]
disable-user-list=true
[org/gnome/login-screen]
banner-message-enable=true
banner-message-text='Corporate banner message text'

# dconf update


Actual results:

Auto login of user configured with TimedLogin option does not work

Expected results:

User configured for TimedLogin should automatically get logged in to the session. After logout from the session same user should automatically get logged in after the time configured in TimedLoginDelay is elapsed.

Additional info:

This was working well in rhel7.1 with gdm-3.8.4-32.el7.x86_64
Problem is introduced in rhel7.2 after re-base to gdm-3.14
Re-enabling user list is a workaround which does work to get timed login working on rhel7.2 But banner message configuration is not possible with this.
