Whether or not to use Single Sign On (SSO) to authenticate to SharePoint Online.
When set to true, Single Sign On (SSO) will be used to authenticate to SharePoint Online using the account specified via User and Password. Active Directory Federation Services (ADFS), OneLogin, and OKTA SSO identity providers are supported.
If you need to use a local ADFS instance to perform authentication, STSURL must be set to the URL of the local instance.
SSO is only applicable when using SharePoint Online. SSO is not supported for On-Premise versions of SharePoint.
