getdap4 does not correctly handle HTTP simple authorization

[jgallagher59701]

When I user getdap4 to access data from the TDS at unidata:
getdap4 -D https://thredds-test.unidata.ucar.edu/thredds/dap4/dev/d4icomp/restricted/SimpleGroup.nc4

I get:

ERROR: Error while reading the URL: https://thredds-test.unidata.ucar.edu/thredds/dap4/dev/d4icomp/restricted/SimpleGroup.nc4.dap?.
The OPeNDAP server returned the following message:
Forbidden: Contact the server administrator.

Using this for .netrc:

hyrax/libdap4 % more ~/.netrc
machine thredds-test.unidata.ucar.edu
        login opendapTestUser
        password xxxyyyzzz <-- look in slack for this

@jgallagher59701 is is possible to print out all the redirects with getdap4? For example, with curl: curl -i -v.

For a long time, the TDS was having some issues with authentication when serving dap4 data (It would return Forbidden). It should be fixed on their end and I can confirm that I can download the dap response with requests.Session (i.e. pydap)

Also, is getdap4 configured to always follow redirects?
