Identity and Access Management

Overview

The Identity and Access Management module of ZStack Cube Virtualization Edition provides unified user identity management and access control. It supports centralized management of regular users, configuration of a unified authentication system for single sign-on with ZStack Cube Virtualization Edition, and management of access permissions for all users to platform resources.

Centralized User Management

It supports the unified creation and management of users and user groups.

Precise Role-Based Access Control

Different role permissions can be granted to different users and user groups, allowing you to precisely control the operations that specific users or user groups can perform on particular resources, thereby assisting in maintaining the security of the environment.

Integration with Unified Authentication Systems

It supports configuring a unified authentication system based on OIDC, AD, LDAP protocols for single sign-on (SSO). This allows direct use of users from the unified identity authentication system without the need to create additional users, enhancing management efficiency and reducing security risks.

Preparation

Before using the ZStack Cube Virtualization Edition identity and access management features, ensure that the platform version and license authorization meet the requirements.
  • Make sure the installed software version is ZStack Cube Virtualization Edition 4.10.0 or later.
  • To use the single sign-on system, roles, and user group features, ensure that the ZStack Cube Virtualization Edition is installed with a valid Advanced Edition license.

Single Sign-On

ZStack Cube Virtualization Edition provides unified identity authentication login services, supporting seamless access to the unified authentication login system. Corresponding unified authentication users can log in directly to the virtualization platform and conveniently use platform resources. Currently, OIDC, AD, and LDAP authentication servers are supported.
  • OIDC Authentication: OIDC (OpenID Connect) is an authentication protocol built on the OAuth2 framework, allowing clients to verify user identities and obtain basic user configuration information. Through the OIDC authentication server, user information can be synchronized to the platform according to mapping rules, and OIDC authentication system users can log in to the platform without a password.
  • AD Authentication: AD (Active Directory) is a directory service for Windows Standard Server, Windows Enterprise Server, and Windows Datacenter Server, providing a standalone and standardized login authentication system for increasingly diverse enterprise office applications. Through the AD authentication server, AD users can be synchronized to the virtualization platform, supporting direct login to the platform using specified AD login attributes.
  • LDAP Authentication: LDAP (Lightweight Directory Access Protocol) is a protocol for accessing directory services, providing a standardized directory service for increasingly diverse enterprise office applications. Through the LDAP authentication server, LDAP users can be synchronized to the virtualization platform, supporting direct login to the platform using specified LDAP login attributes.

Role Management

A role is a collection of permissions that, when granted to users and user groups, enables them to invoke related APIs for resource operations. ZStack Cube Virtualization Edition adopts a Role-Based Access Control (RBAC) authorization model, defining resource permissions based on the user's job function (role). Through roles, you can achieve fine-grained control over user permissions.

User Management

A user represents an individual and is the basic unit in identity and access management. Users are created by admins or synchronized from a unified authentication system, and are managed by admins. By sharing resources with users and assigning roles to them, you can achieve fine-grained control over resource ownership and permissions.

Some key features of users include:
  • Users can be either local users or SSO users. Local users are created directly by admins, while SSO users are synchronized from a unified authentication server to the platform.
  • User quotas are standards set by admins to control the total amount of resources allocated to users, including compute resources, data storage resources, network resources.
  • Users can be a member of one or more user groups.
  • Users can be assigned one or more roles. When a user is assigned multiple roles, they will have the combined permissions of those roles. Additionally, once a user joins a user group, they will inherit the roles associated with that group, in addition to any roles they are already assigned.

New User

Create a local user, assign resource ownership and roles, and then use the user to log in.

Before you begin

  • You need to have admin permissions.
  • If you need to use the roles and user groups functionality, Make sure ZStack Cube Virtualization Edition is installed with a valid Advanced Edition license.

Procedure

  1. In the navigation pane, choose System Management > User Management > User.

    Basic Information
    • Username: Set a username for the regular user, which serves as the unique identifier for logging into the platform.
    • Description: Optionally fill in a description for the user.
    • Password: Set a login password for the user.

      The password setting requirements can be adjusted by modifying the Platform Login Password Strength. For more information, see Security Settings.

    • Confirm Password: Re-enter the login password for confirmation.
    • Role: Assign roles to the user. After binding, the user will have the permissions associated with the role.
    • User Group: Add the user to a user group. After joining, the user will inherit all roles and shared resources from the user group.
    Share Resource

    Specify the resources to be shared with the current user, including virtual machines, images, templates, distributed switches, and distributed port groups.

  4. Review the configuration and click OK.

  2. On the User page, select the target user and then click Actions > Delete.
  3. In the Delete User? dialog, carefully read the risk warnings.

Results

Note:
  • The deleted user will no longer be able to log in to the platform, and ownership of their resources will be transferred to admin.
  • Deleting an SSO user does not affect the user information in the source authentication server.

User Group Management

A user group is a collection of users that supports permission control at the group level. With user groups, you can assign permissions to multiple users for easier management. For example, if you have a user group named UserGroup-1 and associate it with roles that involve storage resource permissions, then all users within this group will automatically inherit the role permissions from UserGroup-1. If there's a new user who needs storage resource permissions, you can achieve the necessary permission allocation by adding this user to the UserGroup-1 user group. In case of changes in users, such as replacing old users with new ones, you don't need to modify permissions for each old user individually; instead, you can simply remove the old users from the user group.

Some key features of user groups include:
  • A user group can contain multiple users, and a user can belong to multiple user groups.
  • User groups cannot be nested. User groups can only contain users, not other user groups.
  • A user group can be assigned multiple roles. When a user group is assigned multiple roles, users within the group will inherit the combined permissions of those roles.

New User Group

Create a user group, add users to the group, so that all users under the user group can obtain the corresponding permissions, facilitating unified permission management.
