Dear Ashwin,
I have tested and it's working depending on the netcdf library version
you are using.
With the version 4.1.3 (Ubuntu 14.04 repository package) the only way
it'sembedding the credentials in the URI:
$ ncdump -h
"https://YourUsernameUriEncoded:YourPassword@xxxxxxxxxxxx/thredds/dodsC/files/g/ds083.2/grib1/2000/2000.02/fnl_20000201_06_00.grib1";
For netcdf library version 4.3.3.1, compiled from source, the embedded
credentials on URI it's working.
If you create a .dodsrc on your working directory or $HOME with your
credentials
$ cat .dodsrc
HTTP.CREDENTIALS.USERPASSWORD=YourUsername:YourPassword
$ ncdump -h
"https://rda.ucar.edu/thredds/dodsC/files/g/ds083.2/grib1/2000/2000.02/fnl_20000201_06_00.grib1";
and refering the .netrc file from your .dodsrc, both can be at your
working or $HOME directory
$ cat .netrc
machine rda.ucar.edu login YourUsernamepassword YourPassword
$ cat .dodsrc
HTTP.NETRC=.netrc
$ ncdump -h
"https://rda.ucar.edu/thredds/dodsC/files/g/ds083.2/grib1/2000/2000.02/fnl_20000201_06_00.grib1";
I hope this helps.
Antonio
P.S.: The instructions on the UCAR blog about configuring authentication
are worthless with respect to the cookie parameteres. This is because
UCAR authentication service it's not using them.

Dear Antonio,
Many thanks for giving me your .dodsrc file. I added a couple of
the lines from your .dodsrc file and tried it out and
and I still get the same error. Have you tried downloading from the UCAR site
recently ?
Best regards,
Ashwin.

Hello,
Has anybody been able to use nccopy with redirect-based
authorization and download a netCDF file ? I am referring to this

<http://ncarrda.blogspot.in/2017/07/accessing-rda-opendap-endpoints-with.html>
and I get a authorization failed error even though I have an
appropriate .netrc file as well as dodsrc file. Using standard
python and netCDF python I am able to read http request and
response of metadata pages on RDA - it is only nccopy that is
failing. Does anybody have a working example of nccopy with this
redirect-based authorization ?
Best,
Ashwin.
