Simultaneous distributed application support of multiple identity management systems is provided through the use of virtual web server instances, which enable one identity management system, on physical servers already running a pre-existing web server instance, which enables a different identity management system. Further, an intelligent rules-based determination is implemented to determine whether to route an access request to either the virtual or pre-existing web server instance. Since the virtual web server instances are generated on the same physical server that executes the pre-existing web service instance, the the existing network flow (i.e., a single URL) and physical infrastructure is leveraged to create a simplified approach to managing the simultaneous use of multiple identity management systems across different distributed applications.
