A directory service is a network service that stores, organises and makes resources available to users and application. Resources like e-mail addresses, computers, and devices like printers. It also ensures the computer networks are properly secured.
Provides uniform access, manages and develops user’s access to computing resources; every user has to remember a single username and password. The users can search the directory and access the central and departmental file servers, application and printers across the campus network. It also makes sure the IT security is in good strength. Account management lowers the computing costs by reducing the number of servers needed for their department.
Authentication management is the process of updating passwords and managing other types of authenticators like password, answering personal questions, a smart card etc. For example if you change your password in a school network then it will automatically result in changing your GroupWise password and any other website which the school network is connected like My Big Campus. Another example of authentication is when a security question is asked when you have forgotten your password of your social networking sites.
