---
# Installs OIDC / LDAP using a temporary Groovy page that calls the
# Extension Script Service (services.extension.install).
# Avoids REST job API and any Namespace class import for portability.
#
# Flow:
#  - Bootstrap config renders with both auth backends OFF (already in your role).
#  - This file installs required extensions on the current wiki.
#  - Final config later turns auth ON (already in your role).
#
# Notes:
#  - We print machine-readable markers so Ansible can assert deterministically.
