Provider hosted sharepoint app, create a SharePoint calendar

Question

I creating a provider hosted app that should create a calendarlist in SharePoint. I want it to be a group calendar later on but first I just need to do step 1: Create a calendar.

I cant find any provider hosted guides on how to create a SharePoint-calendar programmatically. I cant find a ListTemplateStyle for calendar so I tried the event-template, I dont know if its goint to work since there's an error showing up when I try to run this code below:

 Uri hostWeb = new Uri(Request.QueryString["SPHostUrl"]);

        using (var clientContext = TokenHelper.GetS2SClientContextWithWindowsIdentity(hostWeb, Request.LogonUserIdentity))
        {
            Web web = clientContext.Web;
            ListCreationInformation listCreator = new ListCreationInformation();
            listCreator.Title = "CompanyCalendar";
            listCreator.Description = "Workcalendar";
            listCreator.TemplateType = (int)ListTemplateType.Events; //106 = events
            //clientContext.Load(web);
            web.Lists.Add(listCreator);
            clientContext.ExecuteQuery();

        }

System.Net.WebException: The remote server returned an error: (401) Unauthorized.

Line 27:                 //clientContext.Load(web);
Line 28:                 web.Lists.Add(listCreator);
Line 29:                 clientContext.ExecuteQuery();
Line 30: 
Line 31:             }

It seems like im unauthorized to create a list here for some reason. I have web permission set to full control and my cert looks like this:

<appSettings>
<add key="ClientId" value="ebcb24ca-afbb-4822-8887-f91504f3d25f" />
<add key="ClientSigningCertificatePath" value="C:\Certs\HighTrustSampleCert.pfx" />
<add key="ClientSigningCertificatePassword" value="1234" />
<add key="IssuerId" value="11111111-1111-1111-1111-111111111111" />
</appSettings>

Any idéas?

my second question is: What do I have to learn to make the calendar a group calendar? Any hints?

Thanks
