HelpDesk Technition Setup - Error Code : 80070005 - Access Denied

I am setting up ADManager Plus for the first time.  I have created a HelpDesk Tech and assigned the roles of Unlock Account and Reset Password.  I login with the technicians account and attempt to unlock a users account.  I get the following error - Error Code : 80070005 - Access Denied.
                New to ADManager Plus?

                  New to ADSelfService Plus?
