Hi Luca,
Thanks for the details below. We're getting proper CMIP5 related group
attributes from the Attribute Service (ATS) at pcmdi9 when asserting the
CMIP5 related data access attributes as you note.
We need to make a few changes to the Gateway to issue these SAML
requests in support of end-to-end authorized file downloads from the TDS
at ESG-NCAR.
The CMIP5 download tests noted below as not requiring CMIP5 registration
for access were made to the GFDL datanode. Other nodes tested (e.g.
pcmdi9, CMCC.it) require CMIP5 registration as expected.
I'll let you know once this is deployed to the production ESG-NCAR
Gateway and pcmdi9 OpenIDs can successfully download. A number of folks
are out on vacation, so it may be a bit until this is ready.
