What is Active Directory?

Current Project Status

Updated: March 14, 2008

We successfully loaded the development Active Directory environment with user accounts (100k+) from the campus LDAP directory. Auto provisioning of security groups based on departments, classification, majors, and course registration is working. Verification that users are being provisioned to the correct groups is underway. Once this testing is complete, we will deploy to our production environment.

We decided that we will synchronize passwords in Active Directory and the campus external Kerberos realm. This decision was made based on information we received from Microsoft and staff at other Universities regarding possible issues with authentication to Exchange 2007, authentication to file shares from non-domain machines, and to applications that still rely on NTLMv2. The logins for workstations that are part of the forest will default to the external Kerberos realm for authentication. It is our hope that one day all applications will be Kerberos aware and we will not have a need to synchronize passwords.

At present, OIT is working on plans for the migration of internal workstations that currently connect to Windows and Novell file servers. Our goal is to start migrating machines to the production environment by the end of this month. During OIT's migration period, we will work out any bugs that we come across and complete our documentation. We remain on schedule with the timeline that was laid out in my February update.

The build out of the production environment is nearly complete except for the following items:

  • Windows Update Server
  • DFS file shares
  • Group Policy
  • File sharing rights

Lastly, we will form a subcommittee to assist with the creation of a MOU that all department administrators and department heads will have to sign before joining the AD. This committee will consist of OIT, departmental administrators, and the campus data stewards. This document will lay out rules that will govern the new environment.

What is Active Directory?

Active Directory (AD) is the database of user accounts, groups, computers, and other resources that comprise a Windows Server based network environment. The user accounts in our Active Directory are created by and synchronized with the campus enterprise directory server using Microsoft's Identity Manager Server 2007.

Brief Project Description:

The purpose of this project is to create a centrally managed infrastructure to maintain and secure Microsoft Windows 2003 and 2008 servers and desktops throughout campus. This infrastructure will provide centralized authentication, authorization, and management services for Windows-based computers and applications. To achieve this goal, units within Office of Information Technology (OIT) and representatives from campus departments are working with an outside consultant to create an AD structure that will be scalable, provide centralized and secure authentication, distributed administration, security, and patch management. A campus Active Directory is required to realize the full potential of other projects such as Microsoft Exchange, Voice over Internet Protocol (VoIP), and SharePoint (MOSS 2007).
