[Zope] module UserFolder problem

I am adding users to an acl_users using userFolderAddUser. What I can't figure out is that after I add a new user, I cannot log in using the username and password used when calling userFolderAddUser. If I manually set the password in acl_users.properties for that user, everything works great. Oh, I am using CookieCrumbler. Has anyone run across this? I'm not sure if this is a CookieCrumbler problem... or what? Thank you! -- Ben Menking IT Security Consulting IT Business Solutions
