Authenticate via HTTP Remote User

Technical Name:
Acsone SA/NV
  • Odoo Version

Terms and Conditions

Allow users to be automatically logged in

This module initialize the session by looking for the field HTTP_REMOTE_USER in the HEADER of the HTTP request and trying to bind the given value to a user. To be active, the module must be installed in the expected databases and loaded at startup; Add the --load parameter to the startup command:

--load=web,web_kanban,auth_from_http_remote_user, ...

If the field is found in the header and no user matches the given one, the system issue a login error page. (401 Unauthorized)

Use case.

The module allows integration with external security systems [1] that can pass along authentication of a user via Remote_User HTTP header field. In many cases, this is achieved via server like Apache HTTPD or nginx proxying Odoo.


When proxying your Odoo server with Apache or nginx, It's important to filter out the Remote_User HTTP header field before your request is processed by the proxy to avoid security issues. In apache you can do it by using the RequestHeader directive in your VirtualHost section

<VirtualHost *:80>
 ProxyRequests Off

 RequestHeader unset Remote-User early
 ProxyPass /  retry=10
 ProxyPassReverse  /
 ProxyPreserveHost On

How to test the module with Apache [2]

Apache can be used as a reverse proxy providing the authentication and adding the required field in the Http headers.

Install apache:

$ sudo apt-get install apache2

Define a new vhost to Apache by putting a new file in /etc/apache2/sites-available:

$ sudo vi  /etc/apache2/sites-available/

with the following content:

<VirtualHost *:80>
  ProxyRequests Off
  <Location />
    AuthType Basic
    AuthName "Test Odoo auth_from_http_remote_user"
    AuthBasicProvider file
    AuthUserFile /etc/apache2/MY_VHOST.htpasswd
    Require valid-user

    RewriteEngine On
    RewriteCond %{LA-U:REMOTE_USER} (.+)
    RewriteRule . - [E=RU:%1]
    RequestHeader set Remote-User "%{RU}e" env=RU

  RequestHeader unset Remote-User early
  ProxyPass /  retry=10
  ProxyPassReverse  /
  ProxyPreserveHost On


The RequestHeader directive is used to add the Remote-User field in the http headers. By default an 'Http-' prefix is added to the field name. In Odoo, header's fields name are normalized. As result of this normalization, the 'Http-Remote-User' is available as 'HTTP_REMOTE_USER'. If you don't know how your specified field is seen by Odoo, run your server in debug mode once the module is activated and look for an entry like:

DEBUG openerp1 openerp.addons.auth_from_http_remote_user.controllers.
Field 'HTTP_MY_REMOTE_USER' not found in http headers
{'HTTP_AUTHORIZATION': 'Basic YWRtaW46YWRtaW4=', ...,

Enable the required apache modules:

$ sudo a2enmod headers
$ sudo a2enmod proxy
$ sudo a2enmod rewrite
$ sudo a2enmod proxy_http

Enable your new vhost:

$ sudo a2ensite

Create the htpassword file used by the configured basic authentication:

$ sudo htpasswd -cb /etc/apache2/MY_VHOST.htpasswd admin admin
$ sudo htpasswd -b /etc/apache2/MY_VHOST.htpasswd demo demo

For local test, add the in your /etc/vhosts file.

Finally reload the configuration:

$ sudo service apache2 reload

Open your browser and go to If everything is well configured, you are prompted for a login and password outside Odoo and are automatically logged in the system.
