[Zope] Multiple FTP sessions for a user.

I need to enable a non-anonymous username to have >1 session (like an anonymous user). The username is used in an MS Outlook macro to upload documents via FTP to the Zope server, which means that the possibility exists for multiple instances of the same username may be connected concurrently to the Zope instance. Currently, if a user connects to the Zope instance using the upload username, subsequent users get a "Connection closed by remote host" error. In addition, the FTP server seems to have a very long timeout setting. I've looked in the ZServer/Medusa code but haven't found the magic bullet for either problem yet. Any help would be appreciated. -- Doug
