I am using CSOM to connect to SharePoint on-premises site. I want to authenticate SharePoint site by using Azure AD, but it returns 401 error.
Please help me. Thanks.

Is your SharePoint on-premises farm linked to a local AD or Azure AD?– Callum CrowleyOct 11, 2022 at 8:59

If your on-premises is linked to local AD, then you can't use Azure AD to authenticate with your SharePoint farm.– Callum CrowleyOct 11, 2022 at 9:41
