NetBackup provides two mutually exclusive methods for controlling user access:
Access Management. Access Management lets you control access to NetBackup by defining user groups and granting explicit permissions to these groups. Configuring user groups and assigning permissions is done using Access Management in the NetBackup Administration Console. Access Management is the newest method and is the preferred method in future NetBackup releases.
Enhanced Authorization and Authentication. Enhanced authentication allows each side of a NetBackup connection to verify the host and user on the other side of the connection. By default, NetBackup runs without enhanced authentication. Enhanced authorization determines if authenticated users (or groups of users) have NetBackup administrative privileges. By default, NetBackup gives administrative privileges to UNIX root administrators or Windows system administrators on NetBackup servers.
