claims augmentation

Claims augmentation in SharePoint 2010 allows administrators to add custom claims beyond the default set provided by Active Directory or other identity providers. This technique is part of implementing claims-based security, which is a key feature in SharePoint 2010 for managing authentication and authorization. By writing a custom claims provider, you can augment the token with additional claims that reflect user attributes or roles specific to your organization. This enables more granular access control and can simplify security management. The process involves developing a custom claims provider that runs during the authentication pipeline, adding claims based on custom logic. This approach is useful for integrating SharePoint with external systems or for scenarios where standard claims are insufficient.
