User And Group Management; Domain Compared To Workgroup Environments - HP 345646-001 - StorageWorks NAS 2000s External Storage Server Administration Manual

User and Group Management

There are two system environments for users and groups: workgroup and domain. Because
users and groups in a domain environment are managed through standard Windows NT or
Windows 2000 domain administration methods, this document discusses only local users and
groups, which are stored and managed on the NAS device. For information on managing users
and groups on a domain, refer to the domain documentation available on the Microsoft
website.

Domain Compared to Workgroup Environments

NAS 2000s devices can be deployed in workgroup or domain environments. When in a
domain environment, the server is a member of the domain. The domain controller is a
repository of accounts and account access for the NAS 2000s. Client machines are also
members of the domain, and users log on to the domain through their Windows clients. The
domain controller also administers user accounts and appropriate access levels to resources
that are a part of the domain.
In a CIFS/SMB environment, when mapping a network drive or a client machine, a user sends
a logon credential to the server. This credential includes the username, password, and if
appropriate, domain information. Using the credential, the server authenticates and provides
the corresponding access to the user.
When a NAS 2000s is deployed into a workgroup environment, all user and group account
access permissions to file resources are stored locally on the server.
By contrast, when a NAS 2000s is deployed into a domain environment it uses the account
database from the domain controller, with user and group accounts stored outside the server.
The server integrates with the domain controller infrastructure.
Note:
and group account information is stored locally, those accounts may be used only to authenticate
logons to the NAS 2000s, resulting in a workgroup configuration.
Administering users and groups in a domain environment is similar in a mechanical sense to
administering them in a workgroup environment. If using an Active Directory domain
controller, the Computer Management tool allows for adding, modifying, and removing users
in the same context as in a workgroup environment. The concepts, however, are very different.
