authenticate to SharePoint through OKTA from back-end service
I have a need to programmatically connect to a customer's SharePoint server that uses OKTA for authentication. I saw this post which looked promising, but cannot seem to get a valid session cookie back from OKTA. I can successfully call the /api/v1/authn endpoint and get back a sessionToken, but when I turn around and call /api/v1/sessions?additionalFields=cookieToken with that session token, I always received a 403 - Forbidden, with the following json: { "errorCode": "E0000005", "errorSummary": "Invalid Session", "errorLink": "E0000005", "errorId": "oaew0udr2ElRfCnZvBFt075SA", "errorCauses":
