Description mariodebian 2010-07-21 18:31:54 UTC 
In older version something like this:

TimedLogin=/etc/gdm/gdm-autologin-script|

Call this script and (based on DISPLAY) return a username string for autologin.

In newer versions daemon/gdm-xdmcp-display.c hardcode empty user and disable autologin:


 static void
 gdm_xdmcp_display_get_timed_login_details (GdmDisplay *display,
                                            gboolean   *enabledp,
                                            char      **usernamep,
                                            int        *delayp)
 {
      
         *enabledp = FALSE;
         *usernamep = g_strdup ("");
         *delayp = 0;


daemon/gdm-xdmcp-display.c don't init dbus connection adn something like this:

GDM_DISPLAY_GET_CLASS (display)->get_timed_login_details (display, enabledp, usernamep, delayp);

don't work.


Please add support for remote TimedLogin again.

Enable remote TimedLogin in new GDM

I propose this simple patch.

In older versions we need a key in config:

[security]
AllowRemoteAutoLogin=true

In gdm > 2.20 this key is no longer avalaible, please re-add it.

Hello All,

Are there any chances to fix this regression bug? We are independent software vendor provider (SCADA/DMS and industry software where industrial automation is used) and use CentOS 5 with GDM version GDM 2.16.0 and RemoteAutoLogin works fine. Now we are trying to migrate to modern version of Centos: v6.0 (and in near future 7) where GDM is in version 2.30.4 and now is impossible for us because of this bug. Keeping the old CentOS 5 is no option for us because of GCC/G++ improvements.

This same bug also exists in Debian bugzilla:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=597504

and as I see mariodebian@gmail.com proposed a patch for resolving this issue.
Regards, Karol Szkudlarek

xdmcp: Allow timed/autologin on remote displays

This commit readds the  security/AllowRemoteAutoLogin key
(deprecated in >= 2.20) and so XDMCP setups can be configured to use
autologin and timedlogin.
