Example text
This centralization of identity information provides additional benefits. The more information the directory stores about any given individual, the broader the range of services that can be performed by the directory for that person. One common data set being integrated with directory services is human resources details, such as department and work assignment. Administrators can establish profiles that designate a set of actions to be carried out based on these criteria. All the people in the marketing department may require the current version of PowerPoint installed, for example, or the Web developers may all require Internet access.
By using the various levels of management capability wisely, you can substantially streamline directory administration. Integrated Security Infrastructure Directory services are acting in critical roles to enable e-commerce, public key infrastructure (PKI) certificates, and support applications that require security services. Most directory services support several security standards and technologies, providing flexible security and access control. A directory service, at a minimum, supports the operations employed in user authentication and access control.
Yet with this increase in granularity and control comes an increased complexity in management of all these assignable rights. Directorywide Single Sign-On Each user on your network typically has an account within the NOS directory and another account for e-mail (at a minimum), each requiring a unique logon name and password. This duplication of logon, and the necessity to remember multiple passwords, leads to one of the more common security concerns in corporate networks today: unsecured passwords.
