Hi, A form requires authentication data for subscription. I handle this data with a python script and create a new user in acl_user with 'member' role. Till there all's OK. Then I add some instructions in this script to log this new user with CookieCrumbler, as indicated in the default provided "login_form" ... context.acl_users.manage_users(submit='Add', REQUEST=context.REQUEST) context.REQUEST.form['__ac_name'] = form['newusername'] context.REQUEST.form['__ac_password'] = form['newpassword'] context.REQUEST.form['__ac_persistent'] = '1' context.REQUEST.form['came_from'] = 'minimum_html' return context.logged_in(context, REQUEST=context.REQUEST) What's strange : 1/ This does not work 2/ The new user is not created when adding the lines that _try to_ log using CookieCrumbler Any idea ? Thanks in advance --Gilles
