A computer-implemented method of extending generic resilient identity services (GRIDS) is provided that comprises: receiving, by a mapping server, a resolve request from an originator endpoint for a locator of a destination endpoint; sending, by the mapping server, a request for authorization to provide the requested locator, the request for authorization indicating an identifier of the originator endpoint; receiving, by a policy server, the request for authorization; accessing, by the policy server, from a database, a set of policies for the destination endpoint; based on the identifier of the originator endpoint and the set of policies for the destination endpoint, sending, by the policy server, an authorization response to the mapping server; and based on the authorization response, sending, by the mapping server, a response to the resolve request to the originator endpoint.
