# Purpose:
# - Ensure base LDAP tree exists (suffix + OUs)
# - Ensure LDAP user entries exist (without setting userPassword here)
# - Set user passwords:
#   * default: on every deploy
#   * optional per-user override: set once on create via password_update: false
# - Keep objectClass list and mail attribute up to date
