In many, if not most, enterprises there are several different e-mail systems, each with their own concept of a directory. Some of these directories are quite sophisticated, others are somewhat simplistic. In any case, there is usually a requirement that the data they contain be as consistent with each other as possible.
PMDF-DIRSYNC provides automated synchronization of such various directories. The directories do not all need to be on the same system; PMDF-DIRSYNC sends directory updates information as e-mail. An overview of PMDF-DIRSYNC's automated operation can be found in Section 37.1.
PMDF-DIRSYNC also has standalone command line utilities for performing independent stages of directory updating, for manual updates or testing purposes. These utilities are described in Section 37.10.
Directory synchronization is provided by the PMDF-DIRSYNC product, not PMDF proper. PMDF-DIRSYNC is a layered product built on top of PMDF. It is licensed separately from the base PMDF product.
