University-Wide Migration from Novell to Active Directory Background Information University-Wide Migration from Novell to Active Directory Background Information • There are roughly 1,200 desktop computers on 2 Hamline campuses (99% of our desktops run Windows XP, 1% Mac/Linux/Other) • Close to 100 server-class computers provide various services on the Hamline network (Hamline servers run Novell Netware, Windows Server or Unix/Linux) • Novell servers at Hamline host Novell’s “directory service” Current Directory Service • A directory service is the central repository of the key elements of a computer network, the place where ITS administrators manage users, computers, network folders, email, etc. • Hamline uses Novell’s directory service for: – Login/authentication to network resources – Network-based file storage – Networked printers/digital imagers – Groupwise email Novell’s Legacy at Hamline • Novell’s technology has served Hamline well for over a decade; Novell was chosen because: – Novell was the market leader at the time – It provided the full range of network services Hamline needed – It was less expensive than the technology of emerging competitors – Novell support was robust and most software products were designed to work with Novell Why Transition? • Interoperability – Microsoft Active Directory (AD) is now the industry standard –3rd Party software products are now routinely created for AD and rarely for Novell – There is a large knowledge base available to Hamline engineers for AD; meanwhile Novell’s has shrunk significantly •Cost – AD is now more cost-effective than Novell Key Benefits of Moving to AD • Hamline will be able to acquire AD-dependent software products that will improve productivity, communication and teaching and learning –an effect of greater interoperability • Hamline ITS will be able to leverage the latest administrative tools for software installation, desktop patches/updates, etc. and be able to count on the extensive knowledge base in resolving problems – Allowing us to do more with less AD Migration: Project Scope • Hamline ITS must accomplish several significant tasks to ensure the success of the migration to Active Directory (AD): 1. An entire network of Windows servers and network services must be configured from scratch 2. Existing Windows servers must be joined to the new AD 3. Code in Banner and various applications must be altered and integrated into the new environment 4. The University SAN (Storage Area Network), where all data is stored, must be re-configured under AD and all data moved to a new location within the SAN 5. In addition to the migration of end users and their computers, all public lab and podium PC’s must be integrated with AD AD Migration Plan: Introduction 1. Hamline ITS is currently building the new AD environment and planning the migration details 2. The migration will take place in stages over several months, but with minimal interruption for users; during these months users will be connected to both the new and old systems 3. AD user accounts and passwords will be created from the existing Novell user accounts and kept in sync until the migration is complete 4. Access to I:, U: and S: drive data will be maintained during the entire process except for a short period of University-wide downtime Step 1: End User Migration • In a single visit to the user’s computer, the following changes will be made: – The PC will be added to the new AD environment and removed from Novell – Newly-named network print queues (named after various cities of the world) will replace the existing ones (Windows printing replaces Novell printing) – Windows Updates will now point to Hamline’s WSUS server (users will be notified of available updates), and a program called SCCM will replace Zenworks for on-demand installation of applications – Most customized Windows settings will be retained (wallpaper, screen saver, icons, etc.) Step 2: End User Migration • Once Step 1 has been completed for the entire University, Hamline ITS will execute Step 2: – Update code in Banner so that user account changes or additions are passed on to AD – Ensure that all University services and applications are ready to function in an all-AD environment – Move all I: and S: and U: drive data to AD servers (this will require a window of downtime for all shared data) – Retire Novell file and print servers AD Migration Plan: Project End • When Step 2 has been accomplished and any lingering functionality issues are resolved, the migration will be considered complete • While many Novell servers will then be retired, some Novell servers and the Novell directory service will continue to support Groupwise (account information will be synced back to Novell from Active Directory until a replacement for Groupwise is in place) Timeline • November/December 2009 – Migration of ITS – Presentation of Migration Plan to Relevant Campus Stakeholders • January – May 2010 – Step 1 of Migration for all University divisions • May – July 2010 – Step 2 (Hamline ITS) • July – August 2010 –Project End So What Else Is New? • Office 2007 – Schedule –Training • Hamline Windows 7 Upgrade –TBD – Possible Summer 2010 Rollout University-Wide Migration from Novell to Active Directory.

Since then, their use has been extended to partners and customers, thus creating the need to support an increasing number of diverse users and communities. Today, directory services need to accommodate hundreds of millions of users and provide additional services to break identity silos. With the ubiquitous use of mobile devices as well as cloud deployments and the integration of social networks identities into the enterprise fabric, billions of objects are transacted everyday through directory services. Modern directory services now go beyond the initial capability to store objects in an identity repository. Directory solutions have evolved around three foundation services: » Storage: Persisting and maintaining entries representing identities.

  • The 12 Essential Tasks of Active Directory Domain Services
    WHITE PAPER ACTIVE DIRECTORY DOMAIN SERVICES The 12 Essential Tasks of Active Directory Domain Services Using the right tools and processes helps reduce administrative overhead and ensures directory service is always available By Nelson Ruest and Danielle Ruest Sponsored by WHITE PAPER ACTIVE DIRECTORY DOMAIN SERVICES ABSTRACT Active Directory Domain Services (AD DS) administration and management includes Sponsored by 12 major tasks. These tasks cover a wide breadth of business needs and are not all performed solely by AD DS administrators. In fact, administrators can and should delegate several tasks to other members of their technical community, technicians, help desk personnel, even users such as team managers and administrative assistants. While delegation is a way to reduce the amount of work administrators have to do when managing AD DS infrastructures, it really only addresses one or two of the 12 tasks, for example, user and group administration as well as end point device administration. The other ten tasks can be staggering in nature—security, networked service administration, OU-Specific Management, Group Policy Object management and many more—and because of this can take up inordinate amounts of time. You can rely on Microsoft’s built-in tools to reduce some of this workload, but are the native tools enough? Perhaps it’s time to reduce AD DS administration overhead by automating most tasks and tightening internal security. Address this by first, determining what the twelve essential labors of Active Directory are and then, see how you can reduce AD DS workloads through the implementation of proper management and administration tools.

  • Oracle Internet Directory 11G R1
    2 3 Directory services are key building blocks for secure identity-enabled business applications and the underlying enterprise identity management (IdM) architecture. Well-structured and organized directory services are the foundation of efficient and effective security services. This is because all IDM applications and most commercial off the shelf (COTS) business applications that require a standard mechanism to access identity attributes, and the most common way to access identity attributes is using LDAP. Example identity attributes include user credentials, access privileges and profile information. Additionally the modern enterprise has different identity attribute needs than they did when LDAP servers first appeared on the market in the 1990s. This is because modern enterprises often have multiple LDAP storage-based servers as well as identity stored in non-LDAP repositories such as HR or CRM databases. Furthermore, new computing initiatives, such as mobile computing, cloud computing and social networking, require LDAP to manage extremely large number of objects, to deliver high performance to manage dynamic data like location and presence, and to be elastic to grow with the cloud. These requirements led to several challenges in deploying identity related applications within the enterprise: While Microsoft Active Directory is pervasive within enterprises, it does not provide the functionality to be a general purpose Enterprise Directory Service because of limitations imposed on it being the Network Operating System directory for Windows. To address Active Directory limitations, Microsoft provides Active Directory Lightweight Directory Services (AD LDS)1. However, due to AD LDS‟s application specific nature, the 1 AD LDS formerly known as Active Directory Application Mode (ADAM) 4 proliferation of AD LDS within enterprises is like weeds in a garden resulting in cost and manageability issues.

  • Red Hat Enterprise Ipa
    RED HAT ENTERPRISE IPA INTRODUCTION Red Hat Enterprise IPA enables your organization to comply with regulations, reduce risk, and become more efficient. Simply and centrally manage your Linux/Unix users and their authentication today. And in the future, your Linux/Unix machines, services, policy, and audit information. Government and industry compliance regulations, as well as best practice risk reduction principles require an organization to establish: • the administrative users accessing machines and services on those machines • which machines and services users have accessed • the actions those users took • policies to control user access to particular machines and service • policies around password strength to protect against unauthorized access Establishing these things simply and centrally, in addition to the obvious security benefits, brings significant efficiencies such as: • reduced time and manual work in an internal or external audit • reduced time spent adjusting parameters and policies for individual machines • more rapid deployment and migration of workloads in the environment • increased ability to benefit from initiatives such as Red Hat Linux Automation www.dlt.com/redhat Red Hat Enterprise IPA | Karl Wirth EXISTING SOLUTIONS To solve these problems, organizations have essentially three options. Roll your own solution; purchase an expensive proprietary solution; or leverage an existing Microsoft Active Directory infrastructure for your Unix/Linux identity and policy. ROLL YOUR OWN For over a decade, organizations have used Sun’s Network Information Services (NIS) and NIS+ to provide central management of identity and policy for users and machines in the Linux and Unix environment. NIS has some serious weaknesses that could cause NIS to fail some security compliance audits.
