## Presentation

LL::NG is able to transfer (trough REST or SOAP) authentication credentials to another LL::NG portal, like a proxy.

The difference with remote authentication is that the client will never be redirect to the main LL::NG portal. This configuration is usable if you want to expose your internal SSO portal to another network (DMZ).

## Configuration

### External portal

In Manager, go in `General Parameters` > `Authentication modules` and choose Proxy for authentication and users.

Then, go in `Proxy parameters`:

- Internal portal URL: URL of internal portal
- Session service URL (optional): Session service URL (default: same as previous for SOAP, same with “/mysession” for REST)
- Cookie name (optional): name of the cookie of internal portal, if different from external portal
- Authentication level: level given to this authentication
- Use SOAP instead of REST: use a SOAP server (deprecated) instead of a REST one (you must set it if internal portal version is < 2.0). In this cas, “Portal URL” parameter must contains SOAP endpoint (generally http://auth.example.com/index.pl/sessions for 1.9 and earlier, http://auth.example.com/sessions for 2.0)

### Internal portal

The portal must be configured to accept REST or SOAP authentication requests if you've choose to use SOAP. See: REST server plugin or SOAP session backend.
