For an Organizational Unit (OU) without another underlying OU, the property 'vrtProtectedFromAccidentalDeletion' is correctly detected. However, if a Sub-OU is created, then "False" always remains at the parent OU value for 'vrtProtectedFromAccidentalDeletion'.
This effect remains even if the sub-OU is deleted again.
This is a product defect (29826).
This will be fixed in a future release of the product. If you require this immediately corrected, please contact Support for a hotfix referencing the defect ID 29826.
