[Zope] Next try at user auth and role creation

[Oliver Andrich]

Hi,

I just discovered something strange. At least I think that it is strange. I
can assign users Roles that don't exist at all in the system. In my last Email
I tried to create a Role in a system wide context. Well, know I removed the
role add code and just added the user with a fantasy role. Now the management
screen can't handle the user anymore cause the role doesn't exist. But when I
do a acl_users.getUser('admin').getRoles() I get the fantasy role I
    specified. Ok, this is not the solution, but should the manage_user code
    check if the role that is specified exists at all?

Bye, Oliver
