To enable the login process to authenticate the requestor, specify the attribute
    returned in the identity provider's SAML assertion that corresponds to the Pega Platform operator ID. You can also map other attributes from the SAML assertion
    to selected properties and pages that are used by your preauthentication and postauthentication
    activities or by other Pega Platform features such as access control policies.

        Open the authentication service and on the SAML 2.0 tab,

                Map the attributes from your login process to properties and pages that are
                    used by your preauthentication and postauthentication activities or elsewhere in
                        Pega Platform.
