+Subject: [PATCH] session: Don't report service unavailable error as failed
+ authentication
+
+Service unavailable error happens when authentication is performed
+using gdm-fingerprint and fprintd service is terminated
+(either manually or from a timeout).
+
+In those cases, failed authentications were being reported, making the login
+greeter display something like:
+"There were <x> failed login attempts since the last successful login.".
+
+This fixes it.
