The the netcdf-c gihub branch with the fix (assuming it works)
is called netrc.dmh

Dear Antonio,
The support staff gave me the required code
changes. You need to make changes to a file called ocrc.c in a method
called combinecredentials under directory oc2. The support staff will
open a ticket on github and merge the changes and you can presumably
download and rebuild and reinstall at that point.
Best regards,
Ashwin.

Dear Antonio,
Thank you so much for the effort in doing
this. I am extremely grateful given that they are so few who are
actually using this and you are somebody who has always encouraged
me to use nccopy for over a year now ! I am using netcdf-c-4.5-rc1
i.e. the latest netCDF version. I added this line to my .dodsrc
file -
HTTP.CREDENTIALS.USERPASSWORD=winash12@xxxxxxxxx:aaaaa
<mailto:HTTP.CREDENTIALS.USERPASSWORD=winash12@xxxxxxxxx:aaaaa>
and I still get the same error . Yes I totally agree about the
instructions on the UCAR site. I have an open ticket with the
support netcdf and I just hope they are able to figure this one out.
Where did you open the issue? do you have a link to it? The version
4.5 it's a Release Candidate and therefore there is a good chance to
solve it before the final release.
I am enclosing the logs turned on with HTTP.VERBOSE. As you can
see the
* Server auth using Basic with user 'k,ŷ~'
Yes, it should be the username.
Regards
Antonio
it should say winash12@xxxxxxxxx <mailto:winash12@xxxxxxxxx>. So
it is still not picking the username from .netrc or the .dodsrc file.
Best wishes,
Ashwin.

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
<http://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";
<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 <http://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";
<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
<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.
