Due to the increasing interest in Internet-based services, enterprises are trying to make the best use of the advantages provided by an online presence. Moreover, they collaborate in order to provide crossorganizational identity-based services, giving an added value to their traditional services. This poses new challenges regarding identity management between domains. An option to overcome them is to integrate an identity-federation platform with that type of services, but it is a very complex task. In this paper we propose to extend the capabilities of an Open Source application server in order to make it compatible with an identity-federation platform as a basis to support cross-organizational identity-based services, reducing dramatically the integration tax. %P 143-150 %B Proceedings of the 2008 12th Enterprise Distributed Object Computing Conference Workshops %D 2008 %C Washington, USA %R 10.1109/EDOCW.2008.50 %I IEEE Computer Society %L upm3168
