NSA-2400 User’s Guide

This chapter introduces the Sharing screens of the NSA.

Use the Sharing screens to:

• Create and manage user accounts. Users are people who have access rights to the NSA and 

can store files there for later retrieval.

• Create and manage groups. A group is a set of users.

• Create and manage shares. A share is a set of users/groups access permissions mapped to a 

specific folder on a volume. It is equivalent to the Windows concept of a shared folder, but 
is independent of the folder. You can map a share to a network drive for easy and familiar 
file transfer for Windows users.

A Local user or group is a one created on the NSA when the NSA is in Workgroup mode.

Domain users and groups are created on a centralized Windows-based domain controller. This 
list is used by the NSA when authenticating users and/or groups that seek access to a share.

If a user belong to different groups with different access rights to the same share, then the 
more restrictive access right would apply, that is deny access overrides read access, overrides 
read-write access. For example, user Joe belongs to the Sales group. He has read access to the 
MIS share. The Sales group are denied access to this MIS share. Therefore, Joe is also denied 
access to the MIS share.

"

More restrictive access rights override less restrictive ones.

If a user or group is deleted in the domain controller, (but not on the NSA) then it appears as in 
limbo on the NSA.
