DeliverPoint 2007 is a permissions management tool allowing you to report on permissions throughout your entire farm right down to list item level. It is the only fully integrated permission management tool that would enable a site owner or site collection owner to report on permissions locally to the item or object itself.
DeliverPoint SP2 includes the following bugfixes.
1. Object Reference Error when performing a Discover Permissions from the tree view is fixed.
2. Copying permission on a domain user with a name beginning with a zero is fixed.
3. Delete permission error when removing a user when the logged on user is a group owner is fixed.
To install SP2, SP1 of DeliverPoint should be uninstalled and then DeliverPoint 2007 SP2 installed from fresh.
