Sponsor: LDAP was originally developed at the University of Michigan and is being widely supported by vendors in commercial products.
Description: LDAP is a streamlined version of X.500.
Relationship to Records Management: To the degree that a more fully featured standard like X.500 may not be feasible at this time, a lesser means of providing directory services is far better than none. Such services are essential to identify individuals and to provide efficient access to digital certificates required to authenticate digital signatures.
Problems/Issues/Weaknesses: LDAP is by definition a "light weight" standard. Admittedly, it does not meet all of the essential requirements for directory services. That means proprietary extensions will be provided in working products. Proprietary extensions mean that such products will not be interoperable and that agencies may be locked into doing business with a particular vendor regardless of cost, service, and other factors. On the other hand, LDAP appears to provide the most likely pathway to grow into a fully featured standard for directory services.
