# Authentik OIDC Provider for Cameleer
# Provides external identity management with role-based access.
#
# After deployment:
#   1. Access Authentik at http://192.168.50.86:30900/if/flow/initial-setup/
#   2. Create an admin account
#   3. Create an OAuth2/OIDC Provider + Application for Cameleer (see HOWTO.md)
#   4. Set CAMELEER_OIDC_* env vars on the server deployment
