["Roberto Pellegrino" <roberto.pellegrino@quix.it>]

Hi all,
how is possible restrict the access on remote portlet?
I use Pluto with Producer (using wsrp4j) and Liferay and uPortal with
consumer.
I want restrict the acces on remote portlet on the base of username and
password of the end-user.
It is possible? If yes can explain me an example??

Best Regards

Robert
