    Lindorm:User management

    Last Updated:Mar 30, 2026

    In LindormTable, each user starts with no permissions. Use the cluster management system to create users, set passwords, and control access to data at the global, namespace, or table level.

    Prerequisites

    Before you begin, ensure that you have:

    Create a user

    1. In the left navigation pane, choose Data Manager > User Manager.

    2. Click + Add user.

    3. In the Add user dialog box, enter a Username and Password.

    4. Click OK.

    Note

    After you create a user, the password cannot be viewed in the system. If you forget the password, you must reset it using Change password. New users have no permissions by default — grant permissions after creation.

    Delete a user

    1. In the user list, find the user and click Delete in the Operation column.

    2. Click OK.

    Change a password

    1. Click Change password in the Operation column for the user.

    2. In the Change password dialog box, enter a New password.

    3. Click OK.

    Permission management

    Permission levels

    Lindorm defines three permission levels. Permissions flow downward — a higher level automatically covers all resources at lower levels.

    Level Scope
    Global All databases and tables in the cluster
    Database (Namespace) All tables in the specified database, including tables created after the permission is granted
    Table The specified table only

    Example: A user with global read and write permissions can read and write all wide tables in every database in the cluster. A user with read and write permissions on Database 1 can read and write all tables in Database 1 — including any tables added to Database 1 later.

    Permission types

    Permission Operations covered Syntax
    WRITE Write data to tables PUT, BATCH, DELETE, INCREMENT, APPEND, CHECKANDMUTATE
