Why ldap server

The DN format works like geographic coordinates, only in reverse order: it specifies location in the directory by listing each subsection in increasing degrees. These are strings that assign values to attributes, like assigning an email address to a user. The format looks as follows:. Multivalue RDNs treat two attribute values as one, and can be used to differentiate between two RDNs with the same value like two users with the same name — the directory could attach the RDN for their email address to their username to create unique RDNs for each.

A multivalue RDN would be formatted as follows:. Main LDAP servers run on the slapd daemon, and they send changes to server replicas via the slurpd daemon. Now, however, organizations are more often using cloud-hosted directory services that relieve the burden of internal server hosting, security, and management.

Cloud-based LDAP servers also enable organizations to shift their infrastructure to the cloud, take advantage of remote work opportunities, and decrease costs.

The LDAP protocol both authenticates and authorizes users to their resources. When authenticating against an LDAP server in an attempt to gain access to the database, the user is prompted to provide their username and password.

Once a user is successfully authenticated, they need to be authorized to the resource s requested. While different LDAP instances may structure and encode this slightly differently, this is essentially accomplished by assigning permissions with groups and roles in the directory.

If the authenticating user is assigned the correct permissions to access a certain resource, the LDAP protocol will authorize them to it; if not, the protocol will deny access. Back when LDAP originated, the above functions were far more sophisticated than other user management options available.

As the protocol gained in popularity, more IT resources became LDAP-compatible, and new offerings — including cloud LDAP, other authentication protocols, and full directory services — entered the scene to support access to those IT resources. With some cloud directory services like JumpCloud, they can combine this functionality with other protocols to provide users access to virtually all their IT resources.

AD requires domain controllers and works best with Microsoft Windows-based devices and applications. Explore these differences further in our AD vs. LDAP comparison. Until recently, directory tools predominantly functioned within and catered to on-prem Windows-based environments. Companies are now opting for cloud-based, Mac and Linux friendly directory services in place of AD and other on-prem directory models.

Azure AD DS is billed as a domain controller-as-a-service for virtual machines and Windows legacy applications deployed within Azure. For those that want to use LDAP with Azure AD, especially authenticating on-prem applications or storage systems, it can be quite challenging. Cloud LDAP relieves companies of a great deal of directory management burden, from setting up and maintaining the core directory infrastructure to integrating applications and systems into their LDAP-based IdP.

Cloud directory services also tend to use other protocols as well, further widening their scope and accommodating new technologies as they emerge while eliminating the need for an on-prem Active Directory server.

Some cloud LDAP services also include a GUI and technical support, eliminating the need to execute everything with plain-text code although some directory services still provide the option for command-line execution, which can be beneficial for executing operations in bulk and offering expert help where needed. Directories have begun to adopt multi-protocol approaches to address modern, decentralized business environments. The multi-protocol directory leverages many protocols — each for a specific purpose.

The result is that each protocol is less frequently used, but is highly suited to its use cases and remains a critical component of a robust multi-protocol directory. Multi-protocol directory services continue to use LDAP alongside other protocols because of its flexibility, open-source heritage, and stability over the years. Before starting down either path, however, the first step to any LDAP implementation should be planning: your IT team should think carefully about how it wants to organize its directory before implementing anything.

The planning step is especially critical for organizations building their own directories; however, it also helps organizations understand which LDAP solutions would best meet their needs. Without LDAP, IT commonly lacks visibility into user accounts and activity and manually manages resource access, creating a decentralized and unorganized identity and access management IAM model that can lead to redundancies, friction, and security risk.

When organizations realize the cost of implementing a solution is less than the cost of time-intensive manual management and the risks associated with it, they often begin to look at LDAP. There are a few main LDAP solutions most businesses consider:. As a Microsoft product, it is best suited for Windows-based environments. This represents the traditional licensing model that IT organizations know well with Microsoft products.

Significant costs do surround the setup and ongoing management of the infrastructure, though. Cloud LDAP services often include additional protocols in their offering so one tool can grant users access to virtually all their resources. Cloud LDAP uses a cloud-hosted server to provide users access to all their on-prem resources. LDAP has been around for a while. Previous versions of LDAP were around for a few years before that. There have been revisions and clarifications of the protocol since then, and there is still active standards work.

LDAP also uses persistent connections for communicating with a directory server. LDAP directory servers are often used as an authentication repository, and are often used to store sensitive information like passwords and other account details. As such, security is an important aspect of most directory servers. This includes a great deal of password policy functionality, like strong encoding mechanisms and constraints that can prevent users from selecting weak passwords, but it also includes support for a variety of authentication types through SASL the simple authentication and security layer , including the possibility of two-factor options through mechanisms like one-time passwords.

On top of that, directory servers typically provide support for fine-grained access controls that restrict which entries, attributes, and values any individual user can access, and in what ways.
