changing user login password via passwd does not update password to unlock keyring

[Val]

On change of user login password with "passwd", the password to unlock seahorse keyring is not automatically updated. On a subsequent successful login to Gnome/Unity, a user is prompted to enter his/her password in a dialogue window that eventually appears when the user attempts to use a service for which seahorse keeps an authentication token or password: "Enter password to unlock your keyring".

In order to answer this question correctly, the user has to enter his/her OLD password, not the NEW one. All of the people whom I observed responding to this question were confused into thinking they had to enter their new password, which apparently did not work. Only when they entered their old password into the seahorse dialogue, the seahorse keyring was unlocked successfully and their user login password was then updated in the seahorse keyring. Subsequent logins to Gnome/Unity work just fine.

This bug is similar to bug #911426: https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/911426 where essentially the same behaviour was observed with shadow authentication mechanism. In the present case, sss is used for authentication.

A little correction to the above note: in bug #911426, the problem with seahorse keyring not being updated was observed when gnome-control-center was used. In this present case, the problem is observed when "passwd" is used.
