Abstract
An object-based security framework provides automatic caller chain building to track the identity of upstream callers. An application developer can define impersonation settings declaratively using a graphical interface. At runtime, logic outside the application objects handles the caller chain and impersonation, relieving the developer from having to incorporate impersonation logic into the application. A group of special identities are permitted to provide identities of others without themselves being recorded in the chain when the chain traverses a method invocation queue. The framework supports a copy style for the chain to support various caller scenarios. Additionally, a minimum authentication level can be enforced throughout the chain. The caller chain can be used in conjunction with roles, and objects may consult the chain programmatically to enforce a custom security scheme.
