In a server environment, what is the primary purpose of a Directory server?

The primary purpose of a Directory server is to authenticate users and manage credentials. In a server environment, a Directory server acts as a centralized repository for information about users, groups, devices, and other resources. It maintains records of user accounts, their authentication credentials (such as passwords), and various attributes associated with those accounts.

When a user attempts to log into a server or access a resource, the Directory server verifies the user's credentials against its database. This process ensures that only authorized users can gain access to the network and its resources, which enhances security. Additionally, a Directory server often provides features like role-based access control, allowing administrators to define permissions based on user roles and streamline user management tasks.

File storage and sharing, building websites, and resolving domain names to IP addresses are important functions in a server environment but do not describe the primary role of a Directory server. File storage and sharing involve managing data and access to it, website building pertains to web hosting and development, and name resolution typically involves a DNS server rather than a Directory server.
