SAP IAS – Identity Authentication Service
IDP – Identity Provider
The single sign-on through SAP IdP is not turned on by default. When disabled, users can only access SAP Commissions through the SAP Commissions login page, using their user ID and password. To enable it, you need to follow the below steps to configure
Once set up, users authenticated with SAP IAS can log in to SAP Commissions without entering their ID or password. Unauthenticated Commissions users that attempt to access a Commissions URL will be redirected to the SAP Identity Access Management login page for authentication.
You will be provided with two URLs:
- Standard Commissions URL – Users can enter the user ID and password and access SAP Commissions.
- SAP IdP based Commissions URL – This URL prompts users to enter their user ID and password via IdP and redirects users to SAP Commissions.
