5 Best Active Directory Tools and Management Software

Active Directory, or AD as it is often referred to, is Microsoft’s own version of an LDAP directory service. It’s been around since Windows server 2000 and replaced the then-aging domain management features of Windows servers. It is a hugely complex service that takes care of authenticating users and equipment, pinpointing their location and managing access rights. Being so complex, it’s no surprise that several developers have tried to make tools that ease the pain of managing Active Directory. Today, we’re bringing you some of the best Active Directory tools that can be found on the Internet.

We’ll first have a general discussion about directory services, what they are, their purpose and utility, and give you some example of them. Next, we’ll talk about LDAP and X.500, two standardized protocols related to directory services. Then, we’ll briefly talk about the evolution of Microsoft directory services. This will bring us to the core of our matter, the best Active Directory Tools we could find. We’ll give you a brief review of each one.

Directory Services, What They Are

Wikipedia defines a Directory Service as “a mapping between the names of resources in a network and their respective network addresses.” And in its simplest form, this is really all it is. So then, you may ask, is the Domain Name System (DNS) a directory service? The answer is a resounding YES! But if it’s that simple, why is Active Directory so complex?

Active Directory, just like most modern directory services, implements much more functionality than just mapping names to addresses. They are at the core of the network’s security and will contain detailed information about users (user accounts) and resources and are also at the center of the access-control mechanisms of most networks. The modern directory service is a database where most of the information about a network, its resources and users are stored.

A directory service is a hierarchical database of objects, each representing a different entity. Some objects represent users, some represent computers or other available resources such as network shares. Other objects are containers for objects. The hierarchical structure makes finding any single object easier and allows for easy permission management where objects can inherit permissions from their parent.

Our goal is not to make you a directory service expert, though, but rather to give you enough background information to better understand what Active Directory is and where it’s coming from. Let’s have a look at some real-life examples of past and present directory services you may have encountered.

Some Examples

DNS is one of the very first directory services. It dates back to the early eighties. It had–and still has–a single primary purpose: translating hostnames into IP addresses. It’s still in widespread use today and it’s one of the foundations of the Internet.

The Network Information Service, or NIS, was Sun Microsystems’ own implementation of a name service similar to DNS for its Unix ecosystem.

Novell Directory Services—later called eDirectory—was the directory service of Novell Netware networks. Somewhat similar to what Active Directory is today, it was an all-encompassing system not only used for name resolution but also for authentication and access control.

NetInfo was developed by NEXT and, when Apple acquired the company, became the Mac OS’s directory service before being replaced by OpenDirectory.

Finally, NT Domains are another example of a directory service. They are the ancestor of Active Directory. NT Domains were primarily used for access control and authentication purposes.

X.500 And LDAP, Two Directory Services Standards

In the information age, interoperability is more important than ever which causes standards to emerge in every field. Directory services are no different two primary standards exist, LDAP and X.500

The X.500 standard, or more precisely the X.500 series of standards are a group of specifications from the ITU-T covering several aspects of electronic directory services. The first iterations date back to 1988 but X.500 is still in widespread use today.

One of the goals of a set of standard protocols as proposed by X.500 is to ensure interoperability and allow systems from different vendors to interact. X.500 is actually a set of nine individual protocols

The Lightweight Directory Access Protocol, or LDAP, is an open, vendor-neutral, industry standard application protocol for accessing and maintaining distributed directory information services over an IP network. Today, most directory services implementations, including Microsoft’s Active Directory are LDAP-compliant.

LDAP was originally intended as a lightweight alternative protocol for accessing X.500 directory services through the simpler TCP/IP protocol stack. As such, X.500 and LDAP are not mutually exclusive and are instead complementary. For instance, the LDAP specification states that the structure of the directory services database must be X.500 compliant.

LDAP clients can not only read the attributes of objects in a directory services database, they can also modify them. This, of course, means that LDAP is secure and offers an authentication mechanism to protect against unauthorized modifications.

From NT Domain To Active Directory

As stated earlier, Windows NT domains were the first form of directory service in the Microsoft ecosystem. As you could have guessed, they first appeared with Windows NT, back in 1993. They had a centralized database that was located on a domain controller which was primarily responsible for user authentication. The database could be replicated on several domain controllers for redundancy and to ensure that large, multi-site networks could authenticate users locally.

With Windows 2000, Microsoft released Active Directory. It was a much-needed improvement over the traditional domains that had been used for years. Active Directory provides several different services. First and foremost are the domain services. These are the cornerstone of Windows networks. They store information about members of the domain, including devices and users, verifies their credentials, authenticates them, and defines their access rights.

Other important services of Active Directory include Certificate Services which provide a local public key infrastructure. They can create, validate and revoke public key certificates for internal use in an organization. Such certificates can be used to encrypt files, emails, and network traffic. Other services provided by Active Directory include federation services, a type of single sign-on mechanism, and rights management services.

The Best Active Directory Tools

The main characteristic of Active Directory is that it is big and complex. And with this complexity comes administration headaches. Fortunately, many tools have been developed by third parties to address some of the AD administration burdens. Those are the tools we’ve researched and we’re presenting you some of the best we could find. This list is far from extensive as there are simply way too many tools out there.

1. SolarWinds Server & Application Monitor (FREE TRIAL)

SolarWinds is known to make some of the very best network and system administrations tools. We’ve featured SolarWinds product countless times when, for example, we reviewed the best SNMP monitoring tools or the best NetFlow collectors and analyzers. SolarWinds is also famous for its free tools, task-specific tools aimed at administrators.

SolarWinds Server and Application Monitor - ActiveDirectory

It’s no surprise, then, that the SolarWinds Server & Application Monitor is on our list. And while its unassuming name might not lead one to think this is an Active Directory tool, its broad range of functionalities make it a great tool for monitoring and managing Active Directory.

Let’s start by having a look at how the SolarWinds Server & Application Monitor can help with AD management. First, the tool features domain controller monitoring which monitors several operational parameters. It will tell you when CPU usage is getting too high, when a user account is locked out or when there is a login issue.
