c0861b1227 gdm: Handle absence of Fprint.Manager service
We rely on the service to detect whether a fingerprint reader is
present. It is fine to not support fingerprint authentication
when the service is missing, but currently we don't handle this
case at all and end up with a non-functional login screen.

8897385714 Give user 48ms to read each character of a PAM message, earlier it was 16ms
User read time per character has been changed from 16ms to 48ms because the
message of information about last login is displayed for half a sec that is not
a good user experience. So time to read a character is increased to 48ms from 16ms.

5650355da5 gdm: fix handling of removed smartcard at startup
If a smartcard is missing from the reader when we start up,
and the system is configured to disable password authentication,
then we need to ask the user to insert their smartcard.

ff5550c82b util: fix "login card" smartcard detection on unlock screen
We only want to react to the card the user logged in with, at
the unlock screen.  We check "at the unlock screen" by checking
the "reauthenticating" state variable.  That variable is the
wrong one, though. It gets set too late, and in some cases, gets
set at the login screen, too.  We should be checking this._reauthOnly
instead.

This commit fixes that.

4cda61a16a gdm: support pre-authenticated logins from oVirt
oVirt is software for managing medium-to-large scale deployments of
virtual machine guests across multiple hosts. It supports a feature
where users can authenticate with a central server and get
transparently connected to a guest system and then automatically get logged
into that guest to an associated user session.

Guests using old versions of GDM support this single-sign-on capability
by means of a greeter plugin, using the old greeter's extension
API.

This commit adds similar support to the gnome-shell based login screen.

How it works:

* The OVirtCredentialsManager singleton listens for

  'org.ovirt.vdsm.Credentials.UserAuthenticated'

  D-Bus signal on the system bus from the

  'org.ovirt.vdsm.Credentials'

  bus name. The service that provides that bus name is called
  the oVirt guest agent. It is also responsible for interacting
  with the the central server to get user credentials.

* This UserAuthenticated signal passes, as a parameter, the a token
  which needs to be passed through to the PAM service that is specifically
  set up to integrate with the oVirt authentication architecture.
  The singleton object keeps the token internally so it can be queried
  later on.

* The OVirtCredentialsManager emits a signal 'user-authenticated' on
  it's object once the dbus signal is triggered

* When the 'user-authenticated' signal is emitted, the login screen
  tells GDM to start user verification using the PAM service. The
  authentication stack of the service includes a PAM module
  provided by oVirt that securely retrieves user credentials
  from the oVirt guest agent. The PAM module then forwards those
  credentials on to other modules in the stack so, e.g.,
  the user's gnome keyring can be automatically unlocked.

* In case of the screen shield being visible, it also will react on that
  'user-authenticated' signal and lift the shield.
  In that case the login screen will check on construction time if
  the signal has already been triggered, and a token is available.
  If a token is available it will immediately trigger the functionality
  as described above.

a2a5f5df3f gdmUtil: pave way for fingeprint to optionally be default auth service
Currently, fingerprint authentication is always a secondary thing.
If a user wants to swipe their finger when the computer is asking
for a password, so be it.

This commit paves the way for making fingerprint auth optionally
be the main way to authenticate.  Currently there's no way to enable
this, but in a future commit will honor

enable-password-authentication=false

in gsettings.

148f2210ca util: abstract out default auth service in code
Right now, the primary way a user logs in is with
a password. They can also swipe their finger, if their
fingerprint is enrolled, but it's expected the fingerprint
auth service won't ask questions the user has to respond to
by typing. As such, we ignore questions that comes from
anything but the main auth service: gdm-password.

In the future, if a user inserts a smartcard, we'll want
to treat the gdm-smartcard service as the main auth service,
and let any questions from it get to the user.

This commit tries to prepare for that eventuality by storing
the name of the default auth service away in a _defaultService variable
before verification has begun, and then later checking incoming
queries against that service instead of checking against
string 'gdm-password' directly.

Of course, right now, _defaultService is always gdm-password.

87245c7b33 authPrompt: Call next button "Unlock" when user switching
When a ShellUserVerifier is asked to verify a user at the login
screen it will transparently first try to reauthenticate the user
against an existing session and then fall back to logging a user
into a new session.  The former is used for user switching.
It's useful to know which type of verification is happening, so
the next button can be made to say "Unlock" instead of "Sign In" when
a user is already signed in.

This commit exports a new "reauthenticating" property on the
ShellUserVerifier that the auth prompt checks when deciding which
label to use for its next button.

e9584cfcab gdm: don't clear user-verifier on reset automatically
Right, the common code between the login screen and

when GDM sends a reset.

We don't actually always want to clear the messages on
reset in the unlock case, though, so doing it implicitly
is problematic.

to the specific reset handlers.

In some deployments showing a user list at the login
