Sounds to me like there's a bug in your udev rules. Does:
udevadm info --export-db
show the tags and ID_SEAT variable set like you expect?
Other comments:
* You don't need a udev rule to assign something to seat0.
Everything is assigned to seat0 by default.
* Probably unrelated but you may need to enable
'user-authority-in-system-dir' in your lightdm.conf:
[SeatDefaults]
user-authority-in-system-dir=true
* I recommend against setting xserver-vt=7 for seat0 -- let LightDM
choose the VT number for you.
* You don't need to pass -sharevts to X for seat1 -- LightDM will do
that for you.
If you are still unable to get it to work, please post additional
information:
* output of 'udevadm info --export-db'
* X logs
* LightDM logs with debugging turned on (edit /etc/init/lightdm.conf
and change 'exec lightdm' to 'exec lightdm -d')

Title:
lightdm multiseat: no login possible
Status in Light Display Manager:
In Progress
Status in “lightdm” package in Ubuntu:
In Progress
Status in “lightdm” source package in Precise:
Confirmed
Bug description:
I am testing a multiseat setup with precise:
One XServer is running on intel graphics card, a second one is running
on a DisplayLink (usb video) device.
The two greeters are displayed, but without password fields shown so
it is not possible to login. If auto-login is enabled in lightdm.conf
multiseat works fine.
