QGIS » QGIS Application

This server has some open-for-all WFS layers and some which need authentication
http://tampere.navici.com/tampere_wfs_geoserver/tampere_ora/ows?
For example this is free: TYPENAME=tampere_ora:KH_TILASTO
but this is secured: TYPENAME=tampere_ora:ONK_NMR_MVIEW

QGIS has no troubles as long as I am reading just the free layers. Discussion between client and server goes without authentication and both are happy. Trouble begins is I try to read a secured layer. The server sends back "HTTP/1.1 401 Unauthorized" and asks to give credentials. I do not have those and therefore I just ask QGIS to cancel this operation.

The trouble is that after cancelling the trial to read the secured layer QGIS cannot any more get data from the free feature types. This seems to come from that after the cancelled operation QGIS is adding the Authorization header "Authorization: Basic Og==" to the requests and the server is rejecting all of them. Below is an example about how the discussion goes:

GET http://tampere.navici.com/tampere_wfs_geoserver/tampere_ora/ows?SERVICE=WFS&REQUEST=GetCapabilities&VERSION=1.0.0 HTTP/1.1

In an attachment there are all the requests and answers from such a case, I only removed the long XML data contents from GetCapabilities and successfull GetFeature.
