Abstract

The invention is directed to off-peak and just-in-time (JIT) retrieval of directory information to reduce network traffic and load on directory servers and/or data sources by requesting only the information that is currently needed from the directory server, while subsequently updating the directory information during an off-peak period in the case that the directory information retrieved in a JIT manner is outdated. In these embodiments, a hybrid integrator operable with an integration directory capable of retrieving directory information in a JIT manner provides this functionality.
