Introduction
The CTSC subcommittee report on Active Directory Consolidation and Future Governance made four recommendations:
- Nexus and ADS should be merged, and the architecture of the new
campus active directory should be a single domain model. Departmental
and other active directories within the scope of the project should be
phased out, with the new campus active directory providing the services
required.
- The AD Management Committee should be created, and terms of
reference developed. The new committee co-chairs can be tasked with
requesting additional resources, scheduling meetings, etc.
- IST should be responsible for operational management of the core
infrastructure for the consolidated active directory. That is,
acquisition, hosting, configuration, administration, monitoring,
debugging, 7x24 support, disaster recovery, etc., on the set of active
directory core servers (e.g., DCs). Engineering Computing will assist
with the monitoring and debugging of the directory controllers.
- The APIST should, after whatever consultation and information
gathering he deems reasonable, make a decision on whether to create a
new directory, or merge to an existing directory.
After consultation the decision as per recommendation 4 is to merge to
the Nexus domain.
Scope and Objectives
The objective of this project is to implement recommendation 1, merging
Nexus and ADS, and providing the services in that single domain
architecture to enable the phasing out of other applicable active
directory domains on campus.
In working towards this objective, the project team works under the
direction of the AD Management Committee and develops the processes
such that IST is capable of assuming the responsibility for operational
management of the consolidated active directory.
Outline of Work
The project team and the AD Management Committee must establish an
outline of the work involved in merging and determine priority areas
and order of work effort. The following technology areas should be
considered in determining the outline of work:
- establishment of OrganizationalUnit (ou) hierarchy
- establish sound security practices for AD infrastructure itself and for services provided
- considerations for workstations, equipment used by users to obtain services
- migration of workstations from current ADS domain into Nexus domain
- image build(s) for adding new workstations to Nexus domain
- ensuring all people are present in Nexus, and provisioned by WatIAM
- considerations for groups, both provisioned by WatIAM and other methods
- establish naming conventions for groups, devices, workstations, servers, printers, group policies, etc.
- use of IST server infrastructure to manage the environment, including login, application and controller logs.
- software delivery considerations, site licensed, individual licensed and freely available
- software update strategies
- servers hosted in the domain
- migration of applications hosted on servers
Project Deliverables
The primary project deliverable is one active directory that includes
all members of the campus community and hosts the workstations in
computing labs and offices for a highly significant percentage of the
facilities at the University of Waterloo.
By including these two elements, services in the areas of workstation
management, software distribution, authentication services, group
policies, etc. can be provided from a single source to most, if not all,
of the campus community.
Also by merging the Nexus and ADS directories, the delivered Active
Directory is intended to be ready to directly provide necessary services to
other groups who currently manage other AD directories on campus.
Timing
Subject to discussion of time lines for individual areas of work to be
completed, the project should have an overall objective of achieving two milestones by May 1, 2011:
- Most employee logins from individual workstations to the Nexus domain
- IST assumes responsibility for operational management of Nexus
Constraints, Assumptions, Risks
Both the ADS domain and the Nexus domain will be providing production
level services to the campus community during this transition phase.
Change must be carefully managed.
Information Systems and Technology and Engineering Computing are
committed to achieving a merged directory and will seek consensus
solutions for resolving technology differences between the current ADS
and Nexus domain implementations. Where consensus is not achieved in a
reasonable time period, such issues will be identified clearly and
referred to the AD Management Committee for resolution.
Information Systems and Technology and Engineering Computing both
recognize this is a strategic priority for the University of Waterloo
and will provide staff time and priority to complete the project in a
timely manner. Both the AD Management Committee and the Computing
Technology and Services Committee (CTSC) will be provided with regular
updates.
