Multi-Tenancy API Testing Results

🎯 Testing Overview​

Date: July 21, 2025
Environment: Nextcloud Docker Development
Base URL: http://localhost/index.php/apps/openregister/api/

✅ COMPLETED TESTS​

1. Default Organisation Management​

Test ID: 1.1
Status: ✅ PASSED
API Endpoint: GET /organisations
User: admin

Test Command:

curl -u 'admin:admin' -H 'OCS-APIREQUEST: true' -H 'Content-Type: application/json' \
'http://localhost/index.php/apps/openregister/api/organisations'

Response:

{
  'total': 1,
  'active': {
    'id': 1,
    'uuid': 'e410bc36-005e-45b5-8377-dbed32254815',
    'name': 'Default Organisation',
    'description': 'Default organisation for users without specific organisation membership',
    'users': ['admin'],
    'userCount': 1,
    'isDefault': true,
    'owner': 'system',
    'created': '2025-07-21T20:04:39+00:00',
    'updated': '2025-07-21T20:04:39+00:00'
  },
  'list': [...]
}

✅ Validation Results:

  • Default organisation automatically created ✅
  • Admin user auto-assigned to default organisation ✅
  • Correct organisation metadata (isDefault: true, owner: 'system') ✅
  • Proper UUID generation ✅
  • User count calculation working ✅
  • Active organisation set automatically ✅

🔧 TECHNICAL ISSUES RESOLVED​

Issue 1: Dependency Injection Error​

Problem: ObjectService::__construct() expected 16 arguments but only 15 provided
Root Cause: Missing OrganisationService dependency in Application.php
Solution: Added OrganisationService to dependency injection configuration
Files Modified: lib/AppInfo/Application.php

Issue 2: Database Column Mismatch​

Problem: Column 'is_default' not found error
Root Cause: Migration created isDefault column but code looked for is_default
Solution: Updated OrganisationMapper to use correct column name
Files Modified: lib/Db/OrganisationMapper.php

Issue 3: User Membership Validation Race Condition​

Problem: 'User does not belong to this organisation' error during auto-assignment
Root Cause: getActiveOrganisation() added user to memory, then setActiveOrganisation() fetched fresh DB copy
Solution: Set active organisation directly in session without validation when user is auto-assigned
Files Modified: lib/Service/OrganisationService.php

    • Multitenancy enabled ✅
    • Admin override enabled ✅
    • Default organization exists ✅

  2. 🔄 Test User Organization Access - IN PROGRESS

    • Test users can access objects of their own organization
    • Test users cannot access objects of other organizations
    • Verify organization filtering in ObjectEntityMapper

  3. ⏳ Test Admin Access - PENDING

    • Test admin can access all objects (with adminOverride enabled)
    • Test admin can access own organization objects
    • Verify admin override functionality

  4. ⏳ Test RBAC + Multitenancy Integration - PENDING

    • Test both RBAC and multitenancy working together
    • Verify schema-based permissions within organization context
    • Test object ownership permissions

Implementation Details​

Key Files for Multitenancy Logic:

  • lib/Service/SettingsService.php - Configuration management
  • lib/Db/ObjectEntityMapper.php - Object filtering with applyOrganizationFilters()
  • lib/Service/OrganisationService.php - Organization context management
  • appinfo/routes.php - API endpoint definitions
  • lib/Controller/ObjectsController.php - Objects API controller

Critical Logic in ObjectEntityMapper:

// Lines 444-564: applyOrganizationFilters method
// Handles multitenancy filtering and admin override
if ($this->settingsService->getSetting('multitenancy', false) && 
    !($this->settingsService->getSetting('adminOverride', false) && in_array('admin', $userGroups))) {
    // Apply organization filtering
}

📁 Key File References for Testing​

Configuration Management​

File: lib/Service/SettingsService.php

  • Purpose: Handles multitenancy and RBAC configuration
  • Key Methods: getSetting(), settings management
  • Test Endpoint: /api/settings

Object Filtering Logic​

File: lib/Db/ObjectEntityMapper.php

  • Purpose: Core multitenancy filtering for object access
  • Key Method: applyOrganizationFilters() (lines 444-564)
  • Logic: Checks multitenancy enabled + admin override + user groups
  • Filter Types: Organization membership, admin override, RBAC permissions

Organization Management​

File: lib/Service/OrganisationService.php

  • Purpose: User organization context and active organization management
  • Key Methods: getActiveOrganisation(), getUserOrganisations()
  • Session Management: Active organization persistence

API Routes​

File: appinfo/routes.php

  • Objects API: /api/objects - Main testing endpoint
  • Organizations API: /api/organisations - Organization management
  • Settings API: /api/settings - Configuration access

Objects Controller​

File: lib/Controller/ObjectsController.php

  • Key Method: objects() - Uses ObjectService->searchObjectsPaginated()
  • Integration: Works with ObjectEntityMapper for filtering

Expected Behavior​

  1. Regular Users: Should only see objects from their organization(s)
  2. Admin Users: Should see ALL objects (adminOverride enabled) or own organization objects
  3. Cross-Organization: Users should NOT see objects from organizations they don't belong to
  4. RBAC Integration: Schema permissions should work WITHIN organization boundaries

Test Status​

  • Configuration: ✅ VERIFIED
  • User Access Testing: 🔄 IN PROGRESS
  • Admin Access Testing: ⏳ PENDING
  • Cross-Organization Isolation: ⏳ PENDING
  • Documentation: ✅ COMPLETED

🛠️ Debugging Commands & Troubleshooting​

Check User Organization Membership​

# Get user's organizations
docker exec -u 33 master-nextcloud-1 bash -c "curl -s -u 'user1:user1' -H 'OCS-APIREQUEST: true' 'http://localhost/index.php/apps/openregister/api/organisations' | jq '.active'"

Verify Object Counts by User​

# Check objects accessible by admin (should see ALL with adminOverride)
docker exec -u 33 master-nextcloud-1 bash -c "curl -s -u 'admin:admin' 'http://localhost/index.php/apps/openregister/api/objects?_limit=1' | jq '.total'"

# Check objects accessible by regular user (should be filtered)
docker exec -u 33 master-nextcloud-1 bash -c "curl -s -u 'user1:user1' 'http://localhost/index.php/apps/openregister/api/objects?_limit=1' | jq '.total'"

Debug Organization Filtering​

# Check ObjectEntityMapper filtering logic
docker exec -u 33 master-nextcloud-1 bash -c "grep -n 'applyOrganizationFilters' /var/www/html/apps-extra/openregister/lib/Db/ObjectEntityMapper.php"

# Check SettingsService configuration
docker exec -u 33 master-nextcloud-1 bash -c "curl -s -u 'admin:admin' 'http://localhost/index.php/apps/openregister/api/settings' | jq '{multitenancy: .multitenancy, rbac: .rbac}'"

Monitor Debug Logs​

# View real-time debug logs
docker logs -f master-nextcloud-1 | grep -E '\[ObjectEntityMapper\]|\[multitenancy\]|\[organization\]'

# Check for specific multitenancy debug messages
docker logs master-nextcloud-1 --since 10m | grep -i multitenancy

Database Direct Queries​

# Check organization assignments
docker exec -u 33 master-nextcloud-1 bash -c "mysql -u nextcloud -pnextcloud nextcloud -e 'SELECT organisation, COUNT(*) as object_count FROM oc_openregister_objects GROUP BY organisation;'"

# Check user organization memberships
docker exec -u 33 master-nextcloud-1 bash -c "mysql -u nextcloud -pnextcloud nextcloud -e 'SELECT uuid, name, users FROM oc_openregister_organisations;'"

🚨 Common Issues & Solutions​

Issue: Users see wrong number of objects​

  • Check: Organization membership in session vs database
  • Debug: Compare getActiveOrganisation() vs actual object organisation field
  • Solution: Clear organization cache or verify organization assignment

Issue: Admin override not working​

  • Check: adminOverride setting enabled + user in 'admin' group
  • Debug: Log user groups in applyOrganizationFilters()
  • Solution: Verify admin user group membership

Issue: RBAC conflicts with multitenancy​

  • Check: Both systems enabled simultaneously
  • Debug: Check permission layering in ObjectEntityMapper
  • Solution: Verify both filters work together, not conflicting

Issue: Objects not assigned to organization​

  • Check: New objects missing organisation field
  • Debug: Check SaveObject handler and ObjectService
  • Solution: Verify OrganisationService injection and active organization
