NIS Domain 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. Function Local User Management Local Group Management Navigation Path Navigate to the Security > Users screen, from which you can create, view, edit, and delete local users. Navigate to the Security > Groups screen, from which you can create, view, edit, and delete local groups. 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. 40 Snap Server Administrator Guide
