[IDV #MGR-861889]: use IDV as a viewer from thredds, but netcdf file is password protected by thredds

Emanuele,

I can reproduce the error you see. You need to select the correct "Data Source
Type" before clicking the "Add Source" button. Please select "Grid files
(netCDF/GRIB/OPeNDAP/GEMPAK)". You will then be prompted for your authentication
credentials.

Best,

Unidata IDV Support
