#!/usr/bin/env bash
# bootstrap-users.sh — seed required groups in LLDAP
#
# Run AFTER LLDAP is deployed and Running (T05a).
#
# What it does:
#   1. Authenticates to LLDAP via its GraphQL API.
#   2. Creates the two required groups: net-kingdom-users, net-kingdom-admins.
#   3. Prints a user onboarding checklist (groups-only; individual users are
#      added via the WebUI or by re-running this script with USER_EMAIL set).
#
# Groups created:
#   net-kingdom-users    — standard users; all human accounts go here.
#   net-kingdom-admins   — privileged users; KeyCape policies can enforce
#                          MFA step-up or grant extra scopes to this group.
#
# Usage:
#   ./bootstrap-users.sh [lldap-url] [secrets-dir]
#
# <lldap-url>   default: https://lldap.coulomb.social
# <secrets-dir> default: ../../bootstrap/secrets
