I have created a site collection (
http://MySharepointSite:port) with windows authentication (intranet) and extended it to use FBA(extranet). Extended site is a secured site (
https://MySharePointSite).
Now, I want publish a document from ms-word to document library. For this , I am trying to add a
secured website to "My Network Places" and its throwing below error
"The folder you entered doesn't appear to be valid.Please choose another".
I am able to add the intranet site to "My Network Places".Also, I am able to open intranet site as web folder ( internet explorer --> file --> open -->check open as webfolder).
I am using WSS 3.0, MS Office 2007 and Windows XP (client computer).
However, FBA does not support explorer view. Neither protocol can pass FBA credentials through to the explorer shell. So in your current configuration I don't believe it's possible for you to achieve what you're looking for.
