The LDAP server stores this information in a hierarchical UNIX® environment today. Solaris software was originally designed namespace called a Directory Information Tree (DIT). The DIT with the Internet in mind. TCP/IP, the central Internet protocol, has consists of entries that are composed of attribute-value pairs. been at the core of Solaris networking for more than 15 years. Each attribute has a type and can have one or more values.

The LDAP server must support the object classes and attributes that map the Network Information Service model onto LDAP. Several SOLARIS NAMING AND DIRECTORY SERVICE schemas related to Solaris processes, extended accounting, and Solaris Naming and Directory Service combines standard naming more are also supported. and directory technology with enhanced security to provide a comprehensive and reliable naming service. Solaris 8 introduces the Solaris clients can currently authenticate to the LDAP server Lightweight Directory Access Protocol (LDAP) as an access protocol using anonymous and simple mechanism. LDAP can also support for naming services. LDAP is a simple protocol, but delivers a fairly authentication using CRAM-MD5 if the server supports it. Additional robust set of features capable of supporting a diverse set of protection is provided through access control, allowing the server to applications. Apart from update and access capabilities, LDAP grant access for certain containers and/or entries. Access control is also offers a rich set of features for searching. In addition to LDAP specified in the form of access control information (ACIs) on the support, Solaris software continues to support the Domain Name server. Access rights for the directory objects can be specified as read System (DNS), Network Information Service (NIS), and NIS+ and write, with these rights determining what the clients can do to protocols.

Since then, their use has been extended to partners and customers, thus creating the need to support an increasing number of diverse users and communities. Today, directory services need to accommodate hundreds of millions of users and provide additional services to break identity silos. With the ubiquitous use of mobile devices as well as cloud deployments and the integration of social networks identities into the enterprise fabric, billions of objects are transacted everyday through directory services. Modern directory services now go beyond the initial capability to store objects in an identity repository. Directory solutions have evolved around three foundation services: » Storage: Persisting and maintaining entries representing identities.

  • The 12 Essential Tasks of Active Directory Domain Services
    WHITE PAPER ACTIVE DIRECTORY DOMAIN SERVICES The 12 Essential Tasks of Active Directory Domain Services Using the right tools and processes helps reduce administrative overhead and ensures directory service is always available By Nelson Ruest and Danielle Ruest Sponsored by WHITE PAPER ACTIVE DIRECTORY DOMAIN SERVICES ABSTRACT Active Directory Domain Services (AD DS) administration and management includes Sponsored by 12 major tasks. These tasks cover a wide breadth of business needs and are not all performed solely by AD DS administrators. In fact, administrators can and should delegate several tasks to other members of their technical community, technicians, help desk personnel, even users such as team managers and administrative assistants. While delegation is a way to reduce the amount of work administrators have to do when managing AD DS infrastructures, it really only addresses one or two of the 12 tasks, for example, user and group administration as well as end point device administration. The other ten tasks can be staggering in nature—security, networked service administration, OU-Specific Management, Group Policy Object management and many more—and because of this can take up inordinate amounts of time. You can rely on Microsoft’s built-in tools to reduce some of this workload, but are the native tools enough? Perhaps it’s time to reduce AD DS administration overhead by automating most tasks and tightening internal security. Address this by first, determining what the twelve essential labors of Active Directory are and then, see how you can reduce AD DS workloads through the implementation of proper management and administration tools.

  • Oracle Internet Directory 11G R1
    2 3 Directory services are key building blocks for secure identity-enabled business applications and the underlying enterprise identity management (IdM) architecture. Well-structured and organized directory services are the foundation of efficient and effective security services. This is because all IDM applications and most commercial off the shelf (COTS) business applications that require a standard mechanism to access identity attributes, and the most common way to access identity attributes is using LDAP. Example identity attributes include user credentials, access privileges and profile information. Additionally the modern enterprise has different identity attribute needs than they did when LDAP servers first appeared on the market in the 1990s. This is because modern enterprises often have multiple LDAP storage-based servers as well as identity stored in non-LDAP repositories such as HR or CRM databases. Furthermore, new computing initiatives, such as mobile computing, cloud computing and social networking, require LDAP to manage extremely large number of objects, to deliver high performance to manage dynamic data like location and presence, and to be elastic to grow with the cloud. These requirements led to several challenges in deploying identity related applications within the enterprise: While Microsoft Active Directory is pervasive within enterprises, it does not provide the functionality to be a general purpose Enterprise Directory Service because of limitations imposed on it being the Network Operating System directory for Windows. To address Active Directory limitations, Microsoft provides Active Directory Lightweight Directory Services (AD LDS)1. However, due to AD LDS‟s application specific nature, the 1 AD LDS formerly known as Active Directory Application Mode (ADAM) 4 proliferation of AD LDS within enterprises is like weeds in a garden resulting in cost and manageability issues.

  • Red Hat Enterprise Ipa
    RED HAT ENTERPRISE IPA INTRODUCTION Red Hat Enterprise IPA enables your organization to comply with regulations, reduce risk, and become more efficient. Simply and centrally manage your Linux/Unix users and their authentication today. And in the future, your Linux/Unix machines, services, policy, and audit information. Government and industry compliance regulations, as well as best practice risk reduction principles require an organization to establish: • the administrative users accessing machines and services on those machines • which machines and services users have accessed • the actions those users took • policies to control user access to particular machines and service • policies around password strength to protect against unauthorized access Establishing these things simply and centrally, in addition to the obvious security benefits, brings significant efficiencies such as: • reduced time and manual work in an internal or external audit • reduced time spent adjusting parameters and policies for individual machines • more rapid deployment and migration of workloads in the environment • increased ability to benefit from initiatives such as Red Hat Linux Automation www.dlt.com/redhat Red Hat Enterprise IPA | Karl Wirth EXISTING SOLUTIONS To solve these problems, organizations have essentially three options. Roll your own solution; purchase an expensive proprietary solution; or leverage an existing Microsoft Active Directory infrastructure for your Unix/Linux identity and policy. ROLL YOUR OWN For over a decade, organizations have used Sun’s Network Information Services (NIS) and NIS+ to provide central management of identity and policy for users and machines in the Linux and Unix environment. NIS has some serious weaknesses that could cause NIS to fail some security compliance audits.
