Subject: [PATCH 12/12] pam_sss: prefer Smartcard authentication
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The current behavior is that Smartcard authentication is preferred if
possible, i.e. if a Smartcard is present. Since the Smartcard (or
equivalent) must be inserted manually the assumption is that if the user
has inserted it they most probably want to use it for authentication.
With the latest patches pam_sss might receive multiple available
authentication methods. With this patch the checks for available
authentication types start Smartcard authentication to mimic the
existing behavior.
