[gdal-dev] Fwd: Accessing files on password protected OpeNDAP Hyrax servers

[Stanley Glidden]

Hi,

Should gdal (using the dods driver) be able to read data from password protected servers running
OPeNDAP Hyrax? The server I am trying to access is using the Earthdata Login system.

I followed the steps outlined for LDAP access, to create a .netrc and
.dodsrc file:

https://opendap.github.io/hyrax_guide/Master_Hyrax_Guide.html#_authentication_for_dap_clients.


As shown below gdalinfo is denied access, but ncdump is not.

I am able to access opendap servers that are not password protected.
