Comment 4 for bug 498465

Comment from upstream:

"In general this should not be necessary for normal users to do.

 1. The login keyring password should be kept in sync with the user's unix
    password. This occurs automatically when a proper password changing tool
    (such as 'passwd') is used. The tool needs to use the standard PAM
    facilities to change the user's password.

 2. Even if the password gets out of sync, gnome-keyring-2.91.1 and later
    helps to fix the user's password when it gets out of sync. The first time
    its detected that the password for the login keyring and user's unix
    password are out of sync, the user is prompted to enter their old
    password, and the login keyring is then changed to the new password.

If there are additional design changes that are suggested, please add them to
this ticket."
