[Zope] XUF and destination

Having some trouble. I created the sample files for Loginform, etc. in the folder just above the acl_users. When I get my Loginform the destination shows under the box. however, it shows a relative address...all of which is correct for the FULL URL except the http:// part. I have tried variations in the base url field in Membership Sources tab. All to no avail. Suggestions?? Thanks --Allen
