KWallet

Automatisches öffnen der Wallet beim Login (pam_kwallet)

Siehe und KDE Wallet - ArchWiki und How to configure pam_kwallet to auto-unlock kdewallet from sddm login credentials on openSUSE Leap 42.3 KDE Plasma5 · GitHub

Das Passwort der kwallet muss identisch mit dem Passwort für den Benutzerlogin sein und die klassische Verschlüsselung (blowfish) benutzen. GPG als Verschlüsselungsoption geht in diesem Fall nicht.

sudo zypper in pam_kwallet

Kopien der erforderlichen Dateien anlegen

cd /etc/pam.d/
cp common-auth-pc kwallet-auth-pc
cp common-password-pc kwallet-password-pc
cp common-session-pc kwallet-session-pc

Symlinks anlegen

ln -s kwallet-auth-pc kwallet-auth
ln -s kwallet-password-pc kwallet-password
ln -s kwallet-session-pc kwallet-session

kwallet-* Datenen editieren

Auch unter Plasma 6 ist es die /usr/lib64/security/pam_kwallet5.so library!

# kwallet auth stack
auth required pam_env.so
auth optional pam_kwallet5.so

# kwallet password stack

Plasma Anwendungen mit SUDO

Wenn man Anwendungen als Root starteb muss (z.B. Paketmanager Myrlyn), wird für die gestartete Anwendung die Konfiguration des root Users herangezogen, die in der Regel nur eine Standardkonfiguration, z.B: mit sehr kleinen Schriften oder heller Farbgebung ist. Damit die Einstellungen des aktuellen Users übernommen werden, kann man den sudo -E Schalter benutzen:

sudo -E myrlyn
