[Bug 921315] [NEW] lightdm greeter provides no access to pam accounts
Public bug reported:
In our configuration, nearly all users are granted access to the system
via pam. The User Accounts dialog in Settings shows only a single user
which was created at install time...and I'm not sure where from, because
we preseed "d-i passwd/make-user boolean false" to try and inhibit the
initial user account.
We control access with pam_krb5 in common-auth, and pam_access in
common-account, and we want all users passed by that method to be able
to log in (and pam_access is using netgroups to decide which users
should be permitted).
So, in this world, I have one account known to the Accounts Manager, and
it's the only one which lightdm will let me use: I get no "other user"
dialog of any kind. This is a serious bug.
We have the standard unity-greeter.conf and access.conf in /etc/lightdm
(though the latter is supposedly unused). Our lightdm.conf contains
this:
[SeatDefaults]
greeter-session=unity-greeter
user-session=ubuntu
allow-guest=false
autologin-user=
