Linux Entra Bridge

Enables Microsoft Entra ID SSO on Linux via the microsoft-identity-broker D-Bus service

On Linux, Microsoft Entra ID Conditional Access normally works only in Microsoft Edge, because only Edge talks to the Microsoft Identity Broker. Linux Entra Bridge gives Chrome (and Chromium, Brave, Vivaldi) the same capability. A native messaging host (open-source Python) requests the PRT single sign-on cookie from the local microsoft-identity-broker over D-Bus, and the extension sets it for the Microsoft sign-in domains. Chrome then presents as a compliant device to Entra ID, so Microsoft 365, the Azure Portal, and any SAML or OAuth application behind login.microsoftonline.com work without repeated sign-ins. It requires a Linux device enrolled in Microsoft Intune with microsoft-identity-broker running, plus the companion native messaging host from the project page. Everything runs locally; the extension makes no network requests of its own and sends no data to the developer or any third party.
