1. A method for combining off-peak and just-in-time (JIT) retrieval of directory information, the method comprising: providing a hybrid integrator operating with an integration directory capable of retrieving directory information in a JIT manner; receiving a request for directory information at the hybrid integrator; recording the request in the hybrid integrator; forwarding the request to an integration directory after the request is recorded in the hybrid integrator; determining, by the integration directory, a location corresponding to a set of current attribute values for responding to the request; retrieving the set of current attribute values in a JIT manner from at least one of the following: the directory server, and an external source; determining whether each of the set of current attribute values corresponding to the request is current, wherein the determination is delayed until an off-peak period in the case that the request is received during a peak period; and retrieving a set of updated current attribute values based on the determining, wherein the retrieving is delayed until the off-peak period in the case that the request is received during the peak period, and wherein the set of updated current attributes is retrieved from at least one of the following: a directory server, and an external source.
