Some embodiments provide a method and system for flexibly managing access to enterprise resources. To flexibly manage security, some embodiments secure the enterprise resources and provide a security access manager (SAM) to control access to the secured resources. The SAM controls access to the enterprise and the secure resources through one or more configurable management modules of the SAM. Each management module of the SAM is configurable to facilitate control over different security services of an enterprise security hierarchy (e.g., authentication, authorization, role mapping, etc.). Specifically, each management module is configurable to leverage security services that are provided by different security systems. In some embodiments, the management module is configured to interface with one or more adapters in order to establish the interfaces, logic, and protocols necessary to leverage the security functionality of such security systems.
