Virtualized data storage and management of policy and credential data sources

A non-transitory computer readable storage medium including instructions stored thereon which when executed by a processor cause the processor to perform the steps of:

• providing, by an extensible data manager, a unified view of a plurality of storage systems to a plurality of single sign-on services, wherein each single sign-on service is associated with a web interface;
• receiving a data request, at the extensible data manager for a credential from a single sign-on service;
• identifying a storage system associated with the request;
• identifying a storage system plug-in corresponding to the storage system;
• retrieving data associated with the data request from the storage system through the storage system plug-in;
• and
• returning, to the single sign-on service, the requested data.

A system comprising:

• a computer, including a computer readable medium and processor;
• a plurality of single sign-on services, executing on the computer, wherein each single sign-on service is associated with a web interface;
• and
• an extensible data manager, executing on the computer, wherein the data manager includes a plurality of storage system-specific plug-ins, wherein each of the plurality of storage system-specific plug-ins is associated with a different type of storage system that stores credentials and policies, and wherein the type of storage system corresponds to a type of access control;
• wherein the extensible data manager is configured to receive data requests from the plurality of single sign-on services to perform data management operations on the credentials and policies.
