Server-side Authorization<\/h2>\n<\/div>\n<\/div>\n

\n

\n

\n
• The server has three authorization modes. Depending on the authorization mode we choose, the server will decide if it accepts or declines an incoming invocation.<\/li>\n<\/ul>\n

  <\/p>\n<\/div>\n<\/div>\n

  \n

  None<\/h2>\n<\/div>\n

  \n

  \n

  \n
  • This is the simplest type of authorization. No authorization will be performed.<\/li>\n<\/ul>\n<\/div>\n<\/div>\n
    \n

    Self<\/h2>\n<\/div>\n

    \n

    \n

    \n
    • A client will be allowed to use a grid service if the client’s identity is the same as the service’s identity.<\/li>\n<\/ul>\n<\/div>\n<\/div>\n
      \n

      Gridmap<\/h2>\n<\/div>\n

      \n

      \n

      \n
      • A gridmap is a list of ‘authorized users’ akin to an ACL (Access Control List).<\/li>\n
      • When this type of authorization is used, only the users that are listed in the service’s gridmap may invoke it.<\/li>\n<\/ul>\n<\/div>\n<\/div>\n
        \n

        \n

        Client-side Authorization<\/h2>\n<\/div>\n<\/div>\n

        \n

        \n

        \n
        • This allows the client to figure out when it will allow a grid service to be invoked.<\/li>\n
        • This might seem like an odd type of authorization, since authorization is generally seen from the server’s perspective (“Do I allow client FOO to connect to grid service BAR?”).<\/li>\n
        • However, in GSI, clients have every right to be picky about the services they can access.<\/li>\n<\/ul>\n<\/div>\n<\/div>\n
          \n

          None<\/h2>\n<\/div>\n

          \n

          \n

          \n
          • No authorization will be performed.<\/li>\n<\/ul>\n<\/div>\n<\/div>\n
            \n

            Self<\/h2>\n<\/div>\n

            \n

            \n

            \n
            • The client will authorize an invocation if the service’s identity is the same as the client.<\/li>\n
            • If we use both client-side and server-side Self authorization, a service can be invoked if and only if its identity matches the client’s.<\/li>\n<\/ul>\n<\/div>\n<\/div>\n
              \n

              Host<\/h2>\n<\/div>\n

              \n

              \n

              \n
              • The client will authorize an invocation if the host returns an identity containing the hostname.<\/li>\n
              • This is done using host certificates.<\/li>\n<\/ul>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
