[Zope] add user problem

Hi, I have a PythonScript for add a new user in acl_users. It makes: context.acl_user.userFolderAddUser(name,password,['Manager','Owner'],[ ]) The new user is created, but I can't with this name loggen. I did test it with different Zope reliase and it dont work allover. What do I false? Mit schönen Grüßen von Yahoo! Mail. Für die Bilder Ihrer Lieben - Yahoo! Fotos - kostenlos!
