Dear Chris et al,

Thanks already for the investigation. It has worked for several years. I 
installed the NetCDF library via a Centos 7 docker image using conda forge.

Dockerfile:
FROM centos/devtoolset-7-toolchain-centos7:7
USER root
RUN yum update -y && yum install -y bzip2
RUN curl -L -O 
https://repo.continuum.io/miniconda/Miniconda2-latest-Linux-x86_64.sh
RUN bash ./Miniconda2-latest-Linux-x86_64.sh -p /miniconda -b
ENV PATH=/miniconda/bin:${PATH}
RUN conda update -y conda
RUN conda config --add channels conda-forge
RUN conda update -y conda && conda install -y netcdf4
CMD bash

Build with:
docker build -t netcdftest .

Run with:
docker run -it netcdftest bash -c "ncdump -h 
http://opendap.knmi.nl/knmi/thredds/dodsC/CLIPC/tudo/tier3/waterb_arcgis-10-4-0_IRPUD_JRC-LUISA-Landuse_10yr_20100101-20501231.nc";
ncdump:

 NetCDF: Not a valid data type or _FillValue type mismatch

I think I can make a workarround for conda, I will try to use the package 
manager instead.

Cheers,
Maarten

that URL works for me with 4.6.1.

How did you built it? or get it from?

Dear NetCDFGroup,

I have a question: A previous version of ncdump (4.4.1.1) does give a nice 
overview of an OpenDAP URL, while a newer version of ncdump (4.6.2) does not:

Version netcdf library version 4.4.1.1 of Apr 10 2018 03:02:27:
$ ncdump -h

Gives

netcdf waterb_arcgis-10-4-0_IRPUD_JRC-LUISA-Landuse_10yr_20100101-20501231 {
dimensions:
        time = UNLIMITED ; // (5 currently)
        x = 390 ;
        y = 393 ;
variables:
...
}

works, fine while:

netcdf library version 4.6.2 of Dec 17 2018 19:36:03
$ ncdump -h

Am I forgetting something?
