Intune Integration

This module provides integration with Microsoft Intune for Single Sign-On (SSO) and enterprise management features. It handles authentication flow and ensures compliance with Intune policies.

Prerequisites​

Before enabling Intune SSO, ensure the following components are installed and configured:

System Requirements​

  1. Microsoft Identity Broker: The microsoft-identity-broker service must be installed and running

    • Usually provided by Microsoft Intune Company Portal or similar enterprise software
    • Communicates via D-Bus interface com.microsoft.identity.broker1

  2. D-Bus System: Linux D-Bus system bus must be available and functioning

    • Most Linux distributions have this by default
    • Required for communication with the Identity Broker

  3. Valid Intune Account: At least one Intune-managed account must be configured

    • Account must have valid Primary Refresh Token (PRT)
    • Account should have appropriate Teams/Office 365 licenses

Configuration​

Enable Intune SSO in your configuration file. You can place the configuration in either:

User-specific: ~/.config/teams-for-linux/config.json

{
  "auth": {
    "intune": {
      "enabled": true,
      "user": "user@company.com"
    }
  }
}

System-wide (common in enterprise environments): /etc/teams-for-linux/config.json

{
  "auth": {
    "intune": {
      "enabled": true,
      "user": "user@company.com"
    }
  }
}

Configuration Options:

  • auth.intune.enabled: Enable/disable Intune SSO integration (default: false)
  • auth.intune.user: Specific user account to use (default: "" - uses first available account)

Legacy Configuration (deprecated):

The old flat configuration keys are still supported but deprecated:

{
  "ssoInTuneEnabled": true,
  "ssoInTuneAuthUser": "user@company.com"
}

Troubleshooting​

Common Issues​

1. "Failed to find microsoft-identity-broker DBus interface"

  • Ensure Microsoft Identity Broker is installed and running
  • Check if the broker service is accessible: busctl list | grep microsoft.identity

2. "No InTune accounts found"

  • Configure accounts in Microsoft Intune Company Portal
  • Verify accounts are properly enrolled and have valid tokens

3. "Failed to find matching InTune account"

  • Check if auth.intune.user matches an available account (case-insensitive)
  • Verify the account is enrolled in Microsoft Identity Broker

4. "Failed to retrieve Intune SSO cookie"

  • Account may need reauthentication in Company Portal
  • Check if Primary Refresh Token (PRT) is valid

Debug Logging​

Enable debug logging to see detailed Intune diagnostics:

ELECTRON_ENABLE_LOGGING=true teams-for-linux

Look for [INTUNE_DIAG] prefixed messages that provide information about:

  • SSO initialization status
  • Account configuration status
  • Authentication flow
  • Error details and suggestions

Verification​

To verify Intune integration is working:

  1. Start teams-for-linux with debug logging enabled
  2. Look for [INTUNE_DIAG] InTune SSO account configured successfully
  3. The app should automatically authenticate

For configuration options related to Intune SSO, please refer to the Configuration Documentation.
