The first level of security is the login and authentication process. Through assigned rights, logging in to the network and the Directory tree is either granted or denied. If access is granted, a user is then given access only to those servers on which the user has access rights. When a user logs in to a server, that user can access only the volumes, directories and files to which the user again has access rights. Administrators can control rights for users and groups who need access to all resources, such as data and programs that reside in files and directories.
Administrators can also protect all objects from unauthorized access at the server level.
Access to NDS objects is maintained through Authentication . NDS security . This type of security is used to manage the NDS objects, such as access to login scripts, printing, and so on. The network administrator grants or denies a user access to network objects. For example, if a user has operator rights to a Printer object, the user can modify the printing parameters for that object.
