Dave Newton commented on WW-4117:
---------------------------------
It's not the documentation that concerns me.
It's that when I look at a configuration, unless I already know precisely how
it works, I have to look _up_ the docs in order to fully understand the
behavior.
I don't think roles are the right place for this kind of behavior, I think
there's a difference between roles and permissions, although they may be
tightly coupled. Using a single role to represent multiple privileges can lead
to arbitrary combinations of role strings, eventually turning into soup.
Like I said, I'm ambivalent.

>
> The isAllowed method of RolesInterceptor does not enforce the disallowedRoles
> when allowedRoles are configured. ex:
> {code}
> <interceptor-ref name="roles">
> <param name="allowedRoles">authenticated</param>
> <param name="disallowedRoles">restrictedUser</param>
> </interceptor-ref>
> {code}
> With the above configuration a user with the roles "authenticated", and
> "restrictedUser" would be granted access.
