About defining a user group and users
NetBackup authenticates existing users of the operating system instead of requiring that NetBackup users be created with a NetBackup password and profile.
Users can belong to more than one user group and have the combined access of both groups.
Figure: Defining a user group shows defining a user group.
Users can be members of multiple user groups simultaneously, but NetBackup does not allow user groups to be nested. For example, members of a user group can belong to more than one user group, but a user group cannot belong to another user group.
The following figure shows that nested user groups are not allowed.
