[Zope] ExtDocument

Hi, Has anyone try the ExtDocument Product? I'm having troubles with it. Ones I'm on Zope, I try to upload external document to the Zope file System and it asks me for user and password. I tryed the network password, the local password and Zope (mannager) password, and didn't work. So I'm lost in there. Any idea about what the problem is? Thanks Andrés Sánchez Gómez EcMess.com
