Plone Hotfix 2006-10-31
-----------------------

(Plone)PAS using Plone releases up to and including Plone 2.5.1 allowed
creation of accounts with the same name as an existing group. This would
give all access given to the group to the user as well.

This hotfix prevents registration of new users with same id as existing
users and groups.
