It sounds like you are using an unsupported permissions model. The only supported model is to use the Permissions Wizard we ship with Unity.
If you were using the Permissions Wizard it would have set the following rights:
Where imported objects are imported from:
Applied onto User objects
ยท Read properties
ยท Write properties
ยท List contents
Applied onto Group objects
ยท Read properties
ยท Write properties
ยท List contents
Applied onto Contact objects
ยท Read properties
ยท Write properties
ยท List contents
