NIS Domain
40 Snap Server Administrator Guide
Changing Local UIDs or GIDs
The Snap Server automatically assigns and manages UIDs and GIDs. Because you
may need to assign a specific ID to a local user or group in order to match your
existing UID/GID assignments, the Snap Server makes these fields editable.
Local Account Management Tools
The Snap Server offers the following tools for creating, modifying, and editing local
user and group accounts.
Note
Changing a user’s UID will nullify any file system access permissions that
apply to that UID. In addition, any existing permissions for a UID previously
assigned to a user changed to a different UID will become active if another user is
created with the same UID. Carefully consider security configuration on existing
files and directories before changing the UID of a user.
NIS Domain
NIS domains are configured on the
Network > NIS
screen of the Administration Tool.
The Snap Server can join an NIS domain and function as an NIS client. It can then
read the users and groups maintained by the NIS domain. Thus, you must use the
NIS server to make modifications. Changes you make on the NIS server do not
immediately appear on the Snap Server; it may take up to 10 minutes for changes to
be replicated.
Guidelines for Configuring NIS
Handling UID/GID Assignments
Unless UID/GID assignments are properly handled, NIS users and groups may fail
to display properly. For guidelines on integrating compatible Snap Server UIDs, see
“UID and GID Assignments” on page 38.
NIS identifies users by UID, not user name, and although it is possible to have
duplicate user names, Adaptec does not support this configuration.
