Hi, we are using Liferay document library, the files can be accessed via WebDAV. When I try to access the folders with Cyberduck (Version 4.2.1) on Mac, everything works fine. When I try to connect with Cyberduck (Version 4.4.3) on Windows 7, I can't login. It says "Unauthorized. Please contact your web hosting service provider for assistance."
