Authenticator for REST (POST only)

Attached, an authenticator which checks login/password by sumbitting a POST form

The following authenticator allows Yacs to remotely check password by POSTing a form to a remote page.

To use it :

copy the attached file to the "users/authenticators/" directory
in the YACS control panel, setup the following line as remote authenticator : restpost http://www.mydomain.com/authenticate.do username password

The second paramater is the target URL where your login/password can be checked. The last 2 parameters are the field names where username & password are filled in.

The server is expected to return 200 HTTP status code on success. Any other code is a failure.

Comment for developers: to send the POST over a socket, it could have been better to have a new variant 'restpost' managed by the script "services/call.php" (instead of doing its own function to call the server). If this authenticator becomes popular, we could maybe think about adapting this file ?
