How do I use http-authentification with Liferay?

How do I get users to authenticate by http-auth before they can access Liferay?

More specific: How do I use http-auth instead of Liferay's sign-in page or portlets. Acces开发者_如何学Pythons to Liferay should be completely blocked unless credentials have been presented by http-auth.

I can't speak directly to how Liferay works, however, in JBoss Portal you have to manually modify the Portal's web.xml to include the appropriate authentication mechanism and desired roles.

I would assume that Liferay would probably be the same course of action since they are both Java-based web applications at their cores.

I'm not near my (liferay) computer at the moment but you can configure Liferay by placing a portal-ext.properties in the bundle directory, and there are several authentication modules available simply by specifying an alternate class.
