Well, the term "grid portal" can mean many things, so I can't answer your questions in general. For discussion purposes, suppose a grid portal is a "science gateway" based on the "community account model." For more detail about this model, see this paper: http://wally.rit.edu/oajournals/index.php/gce/article/view/99/73 The community account model supposes the gateway possesses a single "community credential" (i.e., users do not possess individual grid credentials). The gateway uses the community credential to request grid services on the users' behalf. The community credential can be stored in MyProxy, yes, but there is no requirement to do so. Indeed, if that's all you're going to use MyProxy for, then it's probably not worth the effort. It's sufficient to store the community credential in a secure file system. The full Globus Toolkit is not needed at the gateway. However, the portal is acting as a grid client so client software is needed. For instance, a java portal might use CoG jglobus to build out its infrastructure. Hope this helps, Tom
