#!/usr/bin/env bash
# Reset an M365 user's password via Graph (app-only, tenant-admin tier).
#
# Usage: reset-password.sh <tenant-id-or-domain> <upn> <new-password> [--force-change]
# --force-change set forceChangePasswordNextSignIn=true (default: false / permanent)
#
# Why this script exists:
# A plain PATCH of passwordProfile works for ordinary members, but Microsoft
# protects admin-role holders: resetting the password of a user who holds a
# directory role (e.g. SharePoint/Teams/User Administrator) requires the CALLER
# to hold Global Administrator or Privileged Authentication Administrator. The
# Tenant Admin app has User.ReadWrite.All but no standing directory role, so it
# gets 403 on admin targets.
#
# This script does a JUST-IN-TIME elevation: if the direct reset 403s, it
# assigns the Tenant Admin service principal the Privileged Authentication
# Administrator role (the app already holds RoleManagement.ReadWrite.Directory),
# retries the reset, then REMOVES the role assignment it created. No standing
# super-privilege is left behind. If the SP already held the role, it is left
# untouched.
#
# Output: human-readable status to stdout. Exit 0 on success.
