This implementation addresses the User Management HLD requirements for centralized user administration in SONiC. sonic-net/SONiC#2018 nexthop-ai/private-sonic-host-services#54 nexthop-ai/private-sonic-utilities#120 **1. YANG Model & Configuration Schema:** - Added sonic-user.yang model defining LOCAL_USER and LOCAL_ROLE_SECURITY_POLICY tables - Integrated user management into CONFIG_DB schema with role-based configuration - Added DEVICE_METADATA.local_user_management feature flag **2. User Management Daemon (userd):** - Implemented C++ daemon using SWSS framework for CONFIG_DB integration - Added user lifecycle management (create/update/delete/enable/disable) - Implemented role-based group assignment (administrator, operator roles) - Added SSH key management with proper file permissions - Integrated PAM faillock configuration using Jinja2 templates **3. CLI Interface:** - Extended sonic-utilities with 'config user' and 'show user' commands - Added user import functionality to migrate existing system users - Added role-based user management with proper validation **4. Build System Integration:** - Added sonic-host-services package with userd daemon and systemd service - Integrated user management into SONiC image build process - Added template-based configuration generation for init_cfg.json - Added build dependencies for JSON processing and password hashing Tested for all the features that are implemented.
