Package: odoo8-addon-auth-from-http-remote-user
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–loadparameter 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. (401Unauthorized)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.ImportantWhen 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>
 ServerName MY_VHOST.com
 ProxyRequests Off
...

 RequestHeader unset Remote-User early
 ProxyPass / http://127.0.0.1:8069/  retry=10
 ProxyPassReverse  / http://127.0.0.1:8069/
 ProxyPreserveHost On
</VirtualHost>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 apache2Define a new vhost to Apache by putting a new file in
/etc/apache2/sites-available:$ sudo vi  /etc/apache2/sites-available/MY_VHOST.comwith the following content:<VirtualHost *:80>
  ServerName MY_VHOST.com
  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
  </Location>

  RequestHeader unset Remote-User early
  ProxyPass / http://127.0.0.1:8069/  retry=10
  ProxyPassReverse  / http://127.0.0.1:8069/
  ProxyPreserveHost On
</VirtualHost>ImportantTheRequestHeaderdirective is used to add theRemote-Userfield 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.

are prompted for a login and password outside Odoo and are automatically
logged in the system.[1]Shibolleth, Tivoli access manager, ..[2]Based on a ubuntu 12.04 envContributorsLaurent Mignon
