Plasma-login-manager: PAM files installed in subdirectories instead of /etc/pam.d/

[tmow]

Description

The plasma-login-manager package (6.4.git20250712-1.1) installs PAM configuration
files inside subdirectories instead of directly in /etc/pam.d/, causing
authentication failures for the greeter.

Current behavior

Files are installed as:

• /etc/pam.d/plasmalogin/plasmalogin
• /etc/pam.d/plasmalogin-greeter/plasmalogin-greeter
• /etc/pam.d/plasmalogin-autologin/plasmalogin-autologin

Expected behavior

Files should be installed as:

• /etc/pam.d/plasmalogin
• /etc/pam.d/plasmalogin-greeter
• /etc/pam.d/plasmalogin-autologin

Symptoms

After enabling the service, the greeter fails to start with:
[PAM] authenticate: Authentication failure
Error from greeter session: “Authentication failure”
Greeter stopped. PLASMALOGIN::Auth::HELPER_AUTH_ERROR

Workaround

Manually copy the files to the correct location:

cd /etc/pam.d                                                                                                                                                                    
sudo mv plasmalogin plasmalogin.d

plasma-login-manager package (6.4.git20250712-1.1)

That version is currently broken and will be removed.

@Yochanan

KDE Plasma users with SDDM can now migrate to Plasma Login Manager

After ensuring plasma-login-manager 6.5.90-1 (or newer) is installed, run the following:

sudo pacman -Syu plasma-login-manager
systemctl disable sddm
systemctl enable plasmalogin
sudo pacman -R sddm-kcm sddm
