You're assuming that all GRAM services are protected by a grid-mapfile, which is not true. > Or is the only way to discover wheter an user has rights to access and > use a GRAM the submission of a test job and looking if the jobs runs or > fails? Well, it seems you'd actually have to make a request to GRAM to exercise the configured authorization chain (which may or may not include gridmap processing). > I am doing tests with GridWay metascheduler.

I don't know if GRAM supports a no-op but it should be possible to implement something analogous to an HTTP HEAD request. Just a thought... Tom
