Actually, I see that there is a problem here. For some reason, we have
        waterb:_Unsigned = "true" ;
instead of false. Need to understand how this can be for a thredds server.

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:

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: Not a valid data type or _FillValue type mismatch

Am I forgetting something?
