Add a SharePoint application
Before you begin
Ensure that:
- Verify that Access Gateway is installed and configured. See Manage Access Gateway deployment.
 - Verify that Access Gateway uses your Okta org as an Identity Provider (IdP). See Configure an Identity Provider in Access Gateway.
 - Verify that you have administrator rights on your Okta org and can create groups and assign applications.
 - Window server configured with IIS application and Active Directory Services running as a Domain Controller and implementing Kerberos (IWA) SSO. 
Note this is an example architecture. It would be unusual in large production environments to have an application server (IIS), also be a DC. - Access Gateway DNS must be served by the Windows DNS server.
 - Confirm that the external app version is supported. Supported Kerberos app versions include:
                    
- Microsoft IIS IWA: IIS 7 or later.
 - Microsoft OWA IWA: IIS 7 or later.
