When a Microsoft document is launched via WebDAV (folder), a prompt comes up for the Windows credentials, once the windows credentials are entered, the document is opened.

'The user login or password is incorrect' for LF credentials and 'Windows Authentication Failed' for using windows authentication.

Any ideas of this:
