Note
If the filesystem containing a user's KWallet files is mounted by pam_mount upon logging on, it may be required to copy ~/.local/share/kwalletd/kdewallet.salt to the same path on the root filesystem. Otherwise, PAM attempts to unlock KWallet before the home directory is available and fails. The file ~/.local/share/kwalletd/kdewallet.kwl which actually contains the encrypted KWallet passwords does not need to be copied.
