[BOUNTY #9] Complete Authentik SSO Integration for All Services

[zhaog100]

Summary

Implements comprehensive SSO solution using Authentik with OIDC/OAuth integration for all 6 services plus ForwardAuth middleware. This PR completes Bounty #9 (00 USDT).

✅ Services Integrated

• ✅ Grafana - Native OIDC with role mapping based on Authentik groups
• ✅ Gitea - OAuth2 with custom app.ini and automated setup script
• ✅ Outline - Native OIDC support with full logout URL
• ✅ Nextcloud - Social Login app with custom OIDC provider and group mapping
• ✅ Open WebUI - Native OIDC with OpenID auto-discovery
• ✅ Portainer - OAuth configuration with environment variables
• ✅ Prometheus - ForwardAuth middleware example for services without native OIDC

🚀 Features Implemented

1. Complete Automation (scripts/authentik-setup.sh)

• Creates all OIDC/OAuth providers automatically (6 services)
• Creates user groups (homelab-admins, homelab-users, media-users)
• Writes client credentials to .env
• Supports --dry-run preview mode
• Outputs comprehensive credential summary

2. Service-Specific Setup Scripts

• scripts/nextcloud-oidc-setup.sh - Installs and configures Social Login app
• scripts/gitea-oidc-setup.sh - Creates OAuth2 authentication source
• scripts/verify-sso-setup.sh - Comprehensive verification (30+ tests)

3. Configuration Files

• config/gitea/app.ini - Complete Gitea configuration with OIDC support
• Updated all docker-compose.yml with OIDC environment variables
• Updated .env.example files with all OAuth variables

4. Comprehensive Documentation

• docs/sso-integration-guide.md (13,000+ words)
  • Quick start guide
  • Integration methods (OIDC vs ForwardAuth)
  • Step-by-step service addition
  • Service-specific examples
  • User group management
  • Troubleshooting guide

5. User Group Permission Isolation

Three user groups with proper access control:

• homelab-admins: Full access to all services + admin panels
• homelab-users: Standard service access
• media-users: Media services only (Jellyfin, Jellyseerr)

✅ Acceptance Criteria

📋 Deployment Instructions

# 1. Configure environment
cd stacks/sso
cp .env.example .env
nano .env  # Fill ALL required values

# 2. Start Authentik
docker compose up -d
docker compose ps  # Wait for healthy (takes ~60s on first run)

# 3. Run setup scripts
../../scripts/authentik-setup.sh  # Creates all OIDC providers
../../scripts/nextcloud-oidc-setup.sh  # Configures Nextcloud
../../scripts/gitea-oidc-setup.sh  # Configures Gitea

# 4. Restart services to pick up new environment variables
cd ../productivity && docker compose restart gitea outline
cd ../storage && docker compose restart nextcloud
cd ../ai && docker compose restart open-webui
cd ../base && docker compose restart portainer
cd ../monitoring && docker compose restart grafana

# 5. Verify setup
../../scripts/verify-sso-setup.sh
