The AuthBasic Handler is a special Handler using AuthBasic method to authenticate and grante access to a virtual host.
|
|
</p>
|
|
|
|
<p>
|
|
The Handler sends a WWW-Authenticate header to the client, to request user id and password. Then it checks credentials by using <abbr title="LemonLDAP::NG">LL::NG</abbr> REST web service (REST session service must be enabled in the manager). Once session is granted, the Handler will check authorizations like the standard Handler.
|
|
</p>
|
|
|
|
<p>
|
|
This feature can be useful to allow a third party application to access a virtual host with user credentials by sending a Basic challenge to it.

You just have to set “Type: AuthBasic” in the virtualHost options in the manager.
|

</p>
|
|

|

If you want to protect only a virtualHost part, keep type on “Main” and set type in your configuration file:

Since 1.9.6, LLNG FastCGI server can handle AuthBasic handler. To call it, you just have to add <code>fastcgi_param VHOSTTYPE AuthBasic;</code> in the FastCGI server call and remove <code>error_page 401</code> directive:

|
|
<pre class="file">location = /lmauth {

internal;
|

include /etc/nginx/fastcgi_params;

|
|
fastcgi_param VHOSTTYPE AuthBasic;
|

|

# Drop post datas

|
fastcgi_pass_request_body off;
|
|
fastcgi_param CONTENT_LENGTH "";
|
|
|
|
# Keep original hostname
|
|
fastcgi_param HOST $http_host;
|
|
|
|
# Keep original request (LLNG server will receive /lmauth)
|
|
fastcgi_param X_ORIGINAL_URI $request_uri;

No parameters needed. But you have to allow sessions web services, see <a href="restsessionbackend.html" class="wikilink1" title="documentation:2.0:restsessionbackend">REST sessions backend</a>.
