Setting up Role Mapping

The Attribute Mapping section also provides mapping for fields named Group/Role.
This attribute will contain the role-related information sent by the Identity Provider (i.e, Salesforce).

The value of this attribute which is mapped to Group/Role will be considered in the Role Mapping section.
