Replication and Distributed Operations extensions
to provide an Internet Directory using X.500
Status of this Memo
This RFC specifies an IAB standards track protocol for the
Internet community, and requests discussion and suggestions for
improvements. Please refer to the current edition of the ``IAB
Official Protocol Standards'' for the standardization state and
status of this protocol. Distribution of this memo is unlimited.
Abstract
Some requirements on extensions to X.500 are described in the
RFC[HK91b], in order to build an Internet Directory using
X.500(1988). This document specifies a set of solutions to the
problems raised. These solutions are based on some work done for
the QUIPU implementation, and demonstrated to be effective in a
number of directory pilots. By documenting a de facto standard,
rapid progress can be made towards a full-scale pilot. These
procedures are an INTERIM approach. There are known
deficiencies, both in terms of manageability and scalability.
Transition to standard approaches are planned when appropriate
standards are available. This RFCwill be obsoleted at this
point.
