[Zope] acl_users

Hi I'm having problems creating a new user in Zope. I want to allow a user access to one folder only, so my thinking was; - create a new user in acl_users and grant 'manager' role - grant access on said folder to manager However, simply adding the new user changes the password for the admin user as well, so i have to resort to a backup to continue (with no new user!). I'm obviously being very dim - I've tried searching the list but can't find anything, any help gratefully received. Manfred --- Outgoing mail is certified Virus Free.
