Greeter: Need to enter password twice and does not remember me

[Stephan Springer]

On a 13.04 desktop system with all updates, I always have to enter my password twice at the desktop login (unity-greeter).

In detail:
* Machine boots, and presents me with the greeter.

Expected behaviour: I am able to select between my name (remembered from the last login) and “guest session”.
Actual behaviour: I can only choose between “login” and “guest session”, with the latter being preselected.

* I choose login, enter my user name, and then my password.

Expected behaviour: I get logged in.
Actual behaviour: The greeter switches back to “guest session”, but this time showing my full name above that, instead of “login”.

* I choose my name and enter the password *again*. Now I finally get logged in.

This is really annoying. And I even have to enter the correct password in both tries! If I enter the wrong password at the first prompt, everything starts over from the beginning.

Status changed to 'Confirmed' because the bug affects multiple users.

behavior continues with saucey

When I type in my password, it takes the first three characters and then remotes those characters then I have to type the whole password over.

If I wait longer I don't have to do this, but I like to type my password as soon as possible, but I have to wait or it will exhibit the behavior I've described.
