Abstract

The TISDAG (Technical Infrastructure for Swedish Directory Access Gateway) project provided valuable insight into the current reality of deploying a wide-scale directory service. This document catalogues some of the experiences gained in developing the necessary infrastructure for a national (i.e., multi-organizational) directory service and pilot deployment of the service in an environment with off-the-shelf directory service products. A perspective on the project's relationship to other directory deployment projects is provided, along with some proposals for future extensions of the work (larger scale deployment, other application areas).

These are our own observations, based on work done and general project discussions. No doubt, other project participants have their own list of project experiences; we don't claim this document is exhaustive!
