Multi-Tenant Architecture ​

Overview ​

Lager Guru implements a comprehensive multi-tenant SaaS architecture that allows multiple organizations (tenants) to use the same application instance while maintaining complete data isolation and security.

Core Principles ​

  1. Tenant ID Everywhere: All business data tables include tenant_id
  2. RLS Enforcement: Database-level security policies enforce tenant isolation
  3. Automatic Filtering: Application code automatically filters by tenant
  4. Service Role Bypass: Background jobs use service role to bypass RLS when needed

Key Components ​

Tenant Table ​

  • id: Unique tenant identifier (UUID)
  • name: Tenant/organization name
  • company: JSONB field for additional company metadata
  • active: Whether the tenant is active

Tenant Users Table ​

  • tenant_id: Reference to tenant
  • user_id: Reference to user profile
  • role: Either tenant_admin or tenant_user
  • Unique constraint on (tenant_id, user_id)

Data Isolation Strategy ​

Row-Level Security (RLS) ​

RLS policies automatically filter queries based on the authenticated user's tenant:

sql
-- Example: Users can only see their tenant's shipments
CREATE POLICY shipments_tenant_isolation ON shipments
  FOR SELECT
  USING (
    tenant_id IN (
      SELECT tenant_id FROM tenant_users
      WHERE user_id = auth.uid()
    )
  );

Application-Level Filtering ​

The application code automatically includes tenant filtering:

typescript
// Automatically filters by current user's tenant
const { data } = await supabase
  .from('shipments')
  .select('*')
  // tenant_id is automatically filtered by RLS

User Roles ​

Super Admin ​

  • Role: admin in user_roles table
  • Access: Can see and manage ALL tenants
  • Use Case: Platform administrators

Tenant Admin ​

  • Role: tenant_admin in tenant_users table
  • Access: Full access to their tenant's data
  • Use Case: Organization administrators

Tenant User ​

  • Role: tenant_user in tenant_users table
  • Access: Read/write access to their tenant's data (with module-specific restrictions)
  • Use Case: Regular employees

Tenant Lifecycle ​

  1. Creation: Super admin creates new tenant
  2. User Assignment: Users are assigned to tenant via tenant_users
  3. Data Isolation: All data automatically scoped to tenant
  4. Deactivation: Tenant can be deactivated without data deletion
  5. Deletion: Cascade deletion removes all tenant data (if needed)

Security Guarantees ​

  1. Database-Level: RLS policies prevent cross-tenant queries
  2. Application-Level: Code always includes tenant context
  3. Service Role: Only used for background jobs, never for user requests
  4. Audit Trail: All operations logged with tenant context

Performance Considerations ​

  • Indexes: tenant_id columns are indexed for fast filtering
  • Query Optimization: RLS policies use efficient subqueries
  • Caching: Tenant context cached in application state
  • Batch Operations: Service role used for bulk operations

SSO Integration ​

OpenID Connect (OIDC) ​

Enterprise SSO support via OpenID Connect protocol.

Configuration Steps ​

  1. Obtain OIDC Provider Information

    • Issuer URL
    • Client ID
    • Client Secret
    • Metadata URL (optional)

  2. Configure in Lager Guru

    • Navigate to System Settings → SSO Integration
    • Add new OIDC provider
    • Enter provider details
    • Toggle Active to enable

  3. Configure Redirect URI in OIDC Provider

    https://your-domain.com/auth/callback/oidc?provider_id={provider_id}&tenant_id={tenant_id}

Authentication Flow ​

  1. User clicks "Mit Unternehmens-SSO anmelden" on login page
  2. User is redirected to OIDC provider's authorization endpoint
  3. User authenticates with OIDC provider
  4. OIDC provider redirects back to Lager Guru with authorization code
  5. Lager Guru exchanges code for tokens
  6. User information is extracted from ID token
  7. User is automatically provisioned into tenant (if new)
  8. User is signed in and redirected to dashboard

User Provisioning ​

When a user logs in via SSO for the first time:

  • A user account is automatically created in Lager Guru
  • The user is assigned to the tenant that initiated the SSO flow
  • Default role: tenant_user (can be changed by tenant admin)

Security Considerations ​

  • State Parameter: OIDC flow uses state parameter to prevent CSRF attacks
  • PKCE: Authorization Code flow with PKCE is used for enhanced security
  • Token Validation: All tokens are validated against the OIDC provider
  • Tenant Isolation: Users can only be provisioned into the tenant that initiated the SSO flow

SAML Integration ​

Enterprise SSO support via Security Assertion Markup Language (SAML) protocol.

Configuration Steps ​

  1. Obtain SAML Provider Information

    • Entity ID / Issuer
    • SSO URL
    • Certificate (X.509)
    • Attribute mappings

  2. Configure in Lager Guru

    • Navigate to System Settings → SSO Integration
    • Add new SAML provider
    • Enter provider details
    • Configure attribute mappings
    • Toggle Active to enable

  3. Configure Assertion Consumer Service (ACS) URL in SAML Provider

    https://your-domain.com/auth/callback/saml?provider_id={provider_id}&tenant_id={tenant_id}

Supported Providers ​

  • Azure AD
  • Okta
  • Auth0
  • Keycloak
  • Any OIDC/SAML-compliant identity provider
