[Nadezhda Ivanova]

Hi Obaid,
I used the control, and it did not help. After all, without it even
Admin would not be able to do the undelete :).
I attempted the exact same thing you describe, but even in ldp the
general user was not able to list the contents of Deleted objects,
control or not. It worked if I bind as Administrator, and that's why I
assume it is an issue with the List Children permissions granted on
Deleted Objects container.

Regards,
Nadya

And it also appears that not even Administrator can grant LC permissions to a user on the Deleted Objects container, so that effectively makes it impossible for any user other than a member of Administrators to perform an undelete... Negative testing works, though - adding ACE's that deny the permissions specified in the docs prevent even a member of Administrators group from performing the op.
