# External authentication
|
|||
|
|
|
|||
|
|
## Overview
|
|||
|
|
|
|||
|
|
The authproxy connector returns identities based on authentication which your
|
|||
|
|
front-end web server performs.
|
|||
|
|
|
|||
|
|
The connector does not support refresh tokens or groups at this point.
|
|||
|
|
|
|||
|
|
## Configuration
|
|||
|
|
|
|||
|
|
The following is an example config file that can be used by the external
|
|||
|
|
connector to authenticate a user.
|
|||
|
|
|
|||
|
|
```yaml
|
|||
|
|
connectors:
|
|||
|
|
- type: authproxy
|
|||
|
|
id: myBasicAuth
|
|||
|
|
name: HTTP Basic Auth
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
The authproxy connector assumes that you configured your front-end web server
|
|||
|
|
such that it performs authentication for the `/dex/callback/myBasicAuth`
|
|||
|
|
location and provides the result in the X-Remote-User HTTP header. The following
|
|||
|
|
configuration will work for Apache 2.4.10+:
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
<Location /dex/callback/myBasicAuth>
|
|||
|
|
AuthType Basic
|
|||
|
|
AuthName "db.debian.org webPassword"
|
|||
|
|
AuthBasicProvider file
|
|||
|
|
AuthUserFile "/etc/apache2/debian-web-pw.htpasswd"
|
|||
|
|
Require valid-user
|
|||
|
|
|
|||
|
|
# Defense in depth: clear the Authorization header so that
|
|||
|
|
# Debian Web Passwords never even reach dex.
|
|||
|
|
RequestHeader unset Authorization
|
|||
|
|
|
|||
|
|
# Requires Apache 2.4.10+
|
|||
|
|
RequestHeader set X-Remote-User expr=%{REMOTE_USER}@debian.org
|
|||
|
|
|
|||
|
|
ProxyPass "http://localhost:5556/dex/callback/myBasicAuth"
|
|||
|
|
ProxyPassReverse "http://localhost:5556/dex/callback/myBasicAuth"
|
|||
|
|
</Location>
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
## Full Apache2 setup
|
|||
|
|
|
|||
|
|
After installing your Linux distribution’s Apache2 package, place the following
|
|||
|
|
virtual host configuration in e.g. `/etc/apache2/sites-available/sso.conf`:
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
<VirtualHost sso.example.net>
|
|||
|
|
ServerName sso.example.net
|
|||
|
|
|
|||
|
|
ServerAdmin webmaster@localhost
|
|||
|
|
DocumentRoot /var/www/html
|
|||
|
|
|
|||
|
|
ErrorLog ${APACHE_LOG_DIR}/error.log
|
|||
|
|
CustomLog ${APACHE_LOG_DIR}/access.log combined
|
|||
|
|
|
|||
|
|
<Location /dex/>
|
|||
|
|
ProxyPass "http://localhost:5556/dex/"
|
|||
|
|
ProxyPassReverse "http://localhost:5556/dex/"
|
|||
|
|
</Location>
|
|||
|
|
|
|||
|
|
<Location /dex/callback/myBasicAuth>
|
|||
|
|
AuthType Basic
|
|||
|
|
AuthName "db.debian.org webPassword"
|
|||
|
|
AuthBasicProvider file
|
|||
|
|
AuthUserFile "/etc/apache2/debian-web-pw.htpasswd"
|
|||
|
|
Require valid-user
|
|||
|
|
|
|||
|
|
# Defense in depth: clear the Authorization header so that
|
|||
|
|
# Debian Web Passwords never even reach dex.
|
|||
|
|
RequestHeader unset Authorization
|
|||
|
|
|
|||
|
|
# Requires Apache 2.4.10+
|
|||
|
|
RequestHeader set X-Remote-User expr=%{REMOTE_USER}@debian.org
|
|||
|
|
|
|||
|
|
ProxyPass "http://localhost:5556/dex/callback/myBasicAuth"
|
|||
|
|
ProxyPassReverse "http://localhost:5556/dex/callback/myBasicAuth"
|
|||
|
|
</Location>
|
|||
|
|
</VirtualHost>
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
Then, enable it using `a2ensite sso.conf`, followed by a restart of Apache2.
