Public bug reported:

It is not possible to switch user from the gnome-screensaver lock dialog
when using lightdm. Although lightdm provides its own gdmflexiserver
implementation, it's not in the default $PATH, so gnome-screensaver
doesn't find it and hides the option to switch user.

Apparently, this was meant to be worked around by adding
/usr/lib/lightdm to the default $PATH:

<seb128> mterry, do you have time for a lightdm bug today? ;-)
<mterry> seb128, sure
<seb128> mterry, the gdmflexiserver path hack still doesn't work...
 mterry, that breaks user switching on the lock screen
<mterry> seb128, guh
 seb128, bug number?
<seb128> I knew you were going to love that :p
 mterry, it was IRC reported but I can file a bug if you want
 let me check if there is one

<mterry> seb128, so to reproduce, I lock my screen and try to switch users?
<seb128> mterry, well basically you uninstall gdm or move its gdmflexiserver away, (restart gnome-screensaver?), then try to lock your screen
 mterry, you should get no "switch user" button
<-- mhr3 has quit (Quit: Ex-Chat)
<seb128> mterry, the code is basically looking if gdmflexiserver is in the path, but it's not

<mterry> seb128, this is without lightdm?
<seb128> mterry, no, that's with lightdm
* mterry wonders why gdmflexiserver isn't in the path

<seb128> mterry, because lightdm install it in /usr/lib/lightdm and your path hack seems to not work (my guess)
 mterry, remember you added code to add /usr/lib/lightdm to the PATH
 which is somewhat hackish ;-)
<mterry> seb128, I remember.  But it was working...
<seb128> well doing a "strings /proc/$(pidof gnome-session)/environ | grep PATH" shows it's not in the path
 mterry, yeah, I blame it on robert_ancell he probably broke it :p
