Red Hat Directory Server

Red Hat Directory Server is an LDAP-compliant server that centralizes user identity and application information. It provides an operating system-independent, network-based registry for storing application settings, user profiles, group data, policies, and access control information.

It features:

• 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
