nginx: TLS Authentication & Authorization
|
|
=========================================
|
|
|
|
.. Warning::
|
|
|
|
Even if this is probably the most secure way to authenticate,
|
|
a lot of clients do not support it. In addition, configuring
|
|
client certificates can also be hard to do for users.
|
|
|
|
This authentication mechanism is recommended for machine to
|
|
machine communication and experienced users.
|
|
|
|
|
|
Background Information
|
|
======================
|
|
|
|
TLS authentication happens when the HTTPS connection is set up and for
|
|
this reason you can not configure it per directory (this information has
|
|
not been received yet). If you want to use this authentication type in
|
|
a custom application, the nginx plugin configures nginx to send you
|
|
the required information like the CN).
|
|
|
|
Configuration
|
|
=============
|
|
|
|
First of all, you need a CA, a client and a server certificate.
|
|
|
|
Please create it like described in :doc:`sslvpn_client`. If you want,
|
|
that your VPN users can log into your application using the same certificate,
|
|
you may use the same CA.
|
|
|
|
.. image:: images/nginx_auth_tls.png
|
|
|
|
Next, choose the CA, the certificate and choose *on* as for client validation.
|
|
This will reject any connection by a client, who has no valid certificate.
|
|
|
|
