I tried doing this. I replaced the top level acl_users with a UserDB that used cookie authentication. Now I can't get into the site at all. Everytime I try to manage or just view the site I get a basic authentication dialog. If I login using either a super-user password or a manager account, nothing is accepted.

This is a serious problem. Can anyone help me reverse or fix the problem.

I am using zope through iis4.0 and it has worked fine up till now.

Try to log in "manually", eg: http://my.site.com/?__ac_name=superuser&__ac_password=123 You may be able to dig further and fix the problem once logged as the superuser Regards, Jephte CLAIN Service Informatique
