Nexus Repository Manager OSS has a Lightweight Directory Access Protocol (LDAP) Authentication realm which provides the repository manager with the capability to authenticate users against an LDAP server. In addition to handling authentication, the repository manager can be configured to map roles to LDAP user groups. If a user is a member of a LDAP group that matches the ID of a role, the repository manager grants that user the matching role. In addition to this highly configurable user and group mapping capability, the repository manager can augment LDAP group membership with specific user-role mapping.
In addition to the basic LDAP support from Nexus Repository Manager OSS, Nexus Repository Manager offers LDAP support features for enterprise LDAP deployments. These include the ability to cache authentication information, support for multiple LDAP servers and backup mirrors, the ability to test user logins, support for common user/group mapping templates, and the ability to support more than one schema across multiple servers.
