When running the build_sidecar program (inside /bes/functions/stare), getdap, and getdap4 on an hdf url an error appears: "The OPeNDAP server returned the following message: Unauthorized: Contact the server administrator."
However, this only seems to be the case when requesting data (dmr, dap, dods). The server will return the metadata when requested through getdap and getdap4. That is the dds and das work.
The error seems to have something to do with HTTPConnect as well as curl, so that may be somewhere to start.
This appears to be a URS/OAuth2 failure.
