Issue

  • We are unable to list site groups using the REST API for the given Sharepoint on-premises server site collection.

​
Resolution

The provided user credentials must be an administrator of the configured site collection.
  • Navigate to the owners page for the Sharepoint server: http://<domain>/_admin/owners.aspx. The page should look like the following (for domain sp-onprem-2016 and site collection /sites/TeamSiteCollection1)
  • Ensure the account used for authenticating via NTLM is a site collection administrator (listed in any of the above boxes).
  • Double-check the username and password inputs.
