[Bug 921315] Re: lightdm greeter provides no access to pam accounts

 

No. We are fine with users who have already logged in having their
username visible; that's helpful.

It's not a lightdm issue, but I'm really quite flabbergasted how even
one user shows up in the accounts manager before anyone has logged in,
on our configuration. In any case, we like the idea that if a user has
logged in on the system they'll be listed in the accounts manager and
lightdm won't hide their username.

But there must always be an "other accounts" if PAM might let in people
that the accounts manager does not know about.

I hope I'm really clear with this...this bug is not merely a cosmetic
bug. It makes the system completely unusable...

Title:
  lightdm greeter provides no access to pam accounts

Status in “lightdm” package in Ubuntu:
  New

Bug description:
  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=
