Original Pull Request: https://github.com/netbirdio/netbird/pull/2060

State: closed
Merged: No

Describe your changes

Adds ClientCertPath and ClientCertKey to the config, to provide mTLS credentials for IDP authentication.
A usecase is having your IDP behind a mTLS terminating reverse proxy, thus reducing the risk of 0 day exploits against your IDP and adding an extra step of authentication.
This is a feature that could be extended to cover netbird management as well.

I would be very happy to have someone more used to the code point out if something is miss placed.
Ideally this could be added to the UI and possibly to mobile clients as well, but i did not want to go poking in the UI code without even an idea if this would be approved.

Issue ticket number and link

Checklist

Is it a bug fix
Is a typo/documentation fix
Is a feature enhancement
It is a refactor
Created tests that fail without the change (if possible)
Extended the README / documentation, if necessary
