Paul, can you share all the changes you had to do, so that we can update
the docs? Or is the line above the only one you had to change?
A direct change to the source file (
https://github.com/qgis/QGIS-Documentation/edit/master/source/docs/pyqgis_developer_cookbook/authentication.rst)
with a pull request for merging would be the most practical way but we'd
also welcome changes within a text-like file or in this thread.

Thanks,
Harrissou

The only trouble is that the getCapabilities statement fails and no layer
