Managing user access to multiple systems is a challenge. In a UNIX environment, providing access based on locally stored information becomes unmanageable as the number of systems and users increases. Storing the user information in a Lightweight Directory Access Protocol (LDAP)-based directory—like Red Hat® Directory Server—makes the system scalable, manageable, and secure.
Gives you centralized, fine-grained access control, including control based on user identity, group membership, role identity, IP address, domain name, or pattern-based rules
Restricts access to directory data with control down to the attribute value level
Allows access anonymously or via authentication methods, like user ID and password or X.509v3 public key certificates
Stores access control list (ACL) information with each entry so that security policy is replicated with the data
Provides the foundation for strong certificate-based authentication when used in conjunction with Red Hat Certificate System
Red Hat Directory Server is an operating system-independent, network-based registry that lets administrators centrally store user identity and application information, like:
• Application settings.
• User profiles.
• Group data.
• Access control information.
Applications can achieve location independence by storing and retrieving preferences in the directory instead of reading separate files on a user's desktop. This lets users work at virtually any computer—as if they were at their own desktops. It also lets IT administrators manage user credentials and profiles in 1 place, regardless of the size or number of apps that use the information.
4-way multimaster replication of data across the enterprise helps ensure high availability. Deploying multiple master servers eliminates write availability as a single point of failure. Red Hat Directory Server also minimizes downtime for administration and maintenance by allowing backups, configuration changes, schema updates, indexing, and restoration of data to occur while the directory is online.
Red Hat Directory Server simplifies user management by eliminating data redundancy and automating data maintenance. 4-way multimaster replication also makes architecting and designing the directory deployment more flexible. Scripts for monitoring and troubleshooting replication simplify the process for administrators. Updates can be simultaneously applied to 1 or more directories, and changes automatically propagate to other participating servers.
By centralizing the management of people and their profiles, Red Hat Directory Server cuts administrative costs. It also allows personalization by acting as a central repository for user profiles and preferences.
