<		In the framework of the Italian Grid Infrastructure, we have designed a web portal which aims at providing a powerful and easy to use gateway to distributed computing resources and cloud services provisioning. We feel that one of the key point that this kind of application must be able to address is the possibility to hide the complexity of the X509 certificates management. Through the portal users can securely run their applications without facing the complexity of the authentication infrastructure. It also interfaces with external Infrastructure as a Service (IaaS) frameworks for the dynamic provisioning of computing resources.

One of the main barriers against Grid widespread adoption in scientific communities stems from the intrinsic complexity of handling X.509 certificates, especially for not HEP communities that don't have a large Grid experience, moreover the only use of command line interface for every type of Grid interaction is discouraging for not expert users.

 Our General purpose Grid portal, based on Liferay, provides exclusively web graphical user interface access to job submission, workflow definition, data management and accounting services. It is also interfaced with external Infrastructure as a Service (IaaS) frameworks for the dynamic provisioning of computing resources. In our model, authentication is demanded to a Identity Federation while the generation and management of Grid credentials is handled securely integrating an On-Line CA with the MyProxy server. In this way the portal gives users full access to Grid functionality without exposing the complexity of X.509 certificates and proxy management.

 Federation Identity is the most used method for authentication and authorization in Academic and Research Institutes. The number of people that have an X509 certificate, and so who can use grid infrastructure, is much minor than the people who belong to a Federation. Our project aims to give the possibility to who belong to a recognized federation to use the grid infrastructure avoiding theme the difficult procedures for requesting and managing X509 certificate. An approach to the grid of this type could be have a very impressive impact on the number of potential communities interested to grid usage, especially for small and not expert communities.

<		Unlike other existing solutions, our portal does not leverage robot certificates for the user credentials. In this way user identity is not obfuscated across the middleware stack thus preserving the functionality and effectiveness of existing distributed accounting and authorization mechanisms. On the other hand, users are not constrained to a predefined set of applications but can freely take advantage of Grid resources power for any computational or data-intensive activity.
