[Zope] Another problem with Login Manager

With the help from yesterday I got the Login Manager started. But if I want to change the userAuthenticate Method there was a problem. I can´t get into the Managementview of my testfolder. Always when I click on the testfolder in the Managementscreen of ZOPE, it returns the index_html of the testfolder in the viewscreen and not in the managementscreen. This problem only returns when I login with my User. With other users it doesn´t. Steffen
