Dear Glenn Wasson, During the SC07 demo NorduGrid would like to use the x509 mutual auth security option. Please configure the tester so that it'll accept our cert. The IGTF approved CA package can be downloaded from nordugrid repository: http://download.nordugrid.org/software/igtf/releases/latest/noarch/ca_NIIF-1... Please let us know what kind of cert the tester is using. Provided the tester is configured properly it supports the x509 method, does it? Citation from you: "Here is the link to the compliance tester. To correct what Steven wrote in the minutes below, the compliance tester can only handle username/password authentication. I will need to install people’s root certs so that the compliance tester (the client) can trust your service for the https connection (required by HPCP), but no X.509 mutual auth is supported right now."
