Intune enroll on redhat 10 KDE

**intune-portal 1.2603.31 fails to authenticate on RHEL 10 KDE Plasma — Misconfiguration(0) in gtk4/actions.rs**

**Environment**

- OS: Red Hat Enterprise Linux 10

- Desktop: KDE Plasma (Wayland, XDG_SESSION_DESKTOP=plasma)

- intune-portal: 1.2603.31-1.el10.x86_64

- microsoft-identity-broker: 3.0.1-1.el10.x86_64

- xdg-desktop-portal-kde: 6.4.5-1.el10_1.x86_64

- webkitgtk6.0: 2.50.4-2.el10_1.x86_64

**Summary**

The Intune portal fails to complete authentication on KDE Plasma. The same machine, same user account, and same tenant works correctly under GNOME on the same RHEL 10 install. The only difference between the working and non-working sessions is XDG_SESSION_DESKTOP (gnome vs plasma).

**Error**

The portal throws the following Rust error when attempting to start a login:

```

[intune-portal/src/gtk4/actions.rs:103:29] e = Error {

context: "Starting a new login",

source: Misconfiguration(

0,

),

}

```

The OneAuth logs show:

- `No accounts found in the OneAuth account store`

- `Auth params authority is empty`

- `MATS device telemetry disabled`

This results in a [4kv4v] error in the Microsoft auth window with Code: 0.

**Additional findings during investigation**

1. On RHEL 10, the KDE portal service is named `plasma-xdg-desktop-portal-kde.service` rather than the expected `xdg-desktop-portal-kde.service`. This means it is not auto-discovered without explicitly starting it, which is a secondary issue.

2. Overriding `XDG_SESSION_DESKTOP=gnome` at launch does not resolve the Misconfiguration(0) error, suggesting the portal reads the session desktop variable at startup rather than at auth time.

3. The auth flow reaches the broker, the broker starts MSAL, but the portal fails to pass authority parameters, so the login flow never presents a credential prompt to the user.

**Steps to reproduce**

1. Install intune-portal 1.2603.31 on RHEL 10

2. Log into a KDE Plasma Wayland session

3. Launch intune-portal and attempt to sign in

4. Observe Misconfiguration(0) error — no login prompt is shown

5. Log out, log into GNOME on the same machine

6. Launch intune-portal — authentication completes successfully

**Expected behaviour**

Authentication should work on KDE Plasma in the same way it does on GNOME.

**Workaround**

None found. Using GNOME is the only current option on this machine.
