LemonLDAP::NG configuration is build around Apache or Nginx virtual hosts. Each virtual host is a protected resource, with access rules, headers, POST data and options.

To protect a virtual host in Apache, the LemonLDAP::NG Handler must be activated (see <a href="configlocation.html#apache" class="wikilink1" title="documentation:2.0:configlocation">Apache global configuration</a>).

Then you can take any virtual host, and simply add this line to protect it:

A virtual host protected by LemonLDAP::NG Handler must be registered in LemonLDAP::NG configuration.
|
|
</p>
|
|
|
|
<p>
|
|
To do this, use the Manager, and go in <code>Virtual Hosts</code> branch. You can add, delete or modify a virtual host here. Enter the exact virtual host name (for example <code>test.example.com</code>) or use a wildcard (for example <code>*.example.com</code>).

|

A virtual host contains:

To send more than <strong>TEN</strong> headers to protected applications, you have to edit and modify :

In other words, headers with <strong>empty values are completely removed</strong> from the passed request.
|
|
<p>
|
|
* <strong>Nginx</strong>, by default, will consider any header that <strong>contains underscores as invalid</strong>. It will remove these from the proxied request. If you wish to have Nginx interpret these as valid, you can set the <code>underscores_in_headers</code> directive to “on”, otherwise your headers will never make it to the backend server.
