ListUser

ListUser is a generic software construct used to retrieve a collection of user accounts from a system's identity store. It may appear as a library function, a class in an admin backend, or a REST API endpoint. The primary purpose is to enumerate users for management, auditing, or presentation.

A typical user record includes user_id, username, display_name, email, status (active, inactive, suspended), roles or groups, and metadata such as last_login and account_created. The source of data can be a relational database, LDAP/Active Directory, or cloud IAM services.

Common usage patterns: call ListUser with optional filters for status, roles, or creation date; apply pagination with page size and page token; specify sort order (e.g., by username or last_login). Example: GET /api/users?status=active&limit=100&cursor=abc123 returns a list and a next-cursor.

Security and privacy: access is typically restricted to administrators or services with appropriate permissions. Sensitive fields should be redacted when presented to non-privileged users. Auditing and rate limiting are advised to prevent misuse. Compliance considerations apply for personal data.

Implementation notes: often implemented as a query against a user store with pagination support; may support caching, field masking, and deltas to reduce data transfer. Error handling includes handling not found, permission denied, and rate limit exceeded.
