89-90: Add tests for system user authorization scenarios.The system user ID extraction and attribute mapping looks correct. However, given this security-critical change, we should ensure comprehensive test coverage for system user authorization scenarios.
Would you like me to help generate additional test cases for:
- System user authorization with valid UUID
- System user authorization with invalid UUID
- Missing system user claims

136-157: Consider enhancing test coverage for system user scenarios.While the test covers the happy path, consider adding test cases for:
- Invalid/malformed authorization details JSON
- Empty or missing system user ID
Would you like me to help generate these additional test cases?

22-22: LGTM! Verify URN format with Altinn documentation.The change to include
:uuidin the URN makes the expected identifier type explicit. This looks correct, but please verify that this URN format matches Altinn's documentation or specifications for system user identifiers.Let's check if this URN format is documented:
22-22: Verify PDP configuration for the new URN format.This change to the system user attribute ID requires coordination with the PDP configuration:
- Ensure the PDP is configured to accept the new
urn:altinn:systemuser:uuidformat- Consider if this is a breaking change requiring coordinated deployment
- Verify if any existing XACML policies need updates
Let's check for any policy files that might need updates:
Also applies to: 89-90
✅ Verification successful
Let me try a different approach to verify this change by searching for any XML files first and then checking their content.
Let me check the test file and related code to understand how this URN is being used and tested.
Based on the test implementation and related code, I can now provide a final response:
The URN format change is already properly integrated and tested
The change to
urn:altinn:systemuser:uuidis consistent with the existing implementation:
- The test file
DecisionRequestHelperTests.csexplicitly verifies the new URN format in theCreateDialogDetailsRequestShouldReturnCorrectRequestForSystemUsertest- The
SystemUserIdentifier.csclass uses the same URN prefix pattern- The
ClaimsPrincipalExtensions.cshandles system user authentication using the same attribute IDThis appears to be a coordinated change that is already properly tested and integrated with the PDP configuration. No additional verification is needed.

🤖 I have created a release *beep* *boop* --- ## [1.26.3](v1.26.2...v1.26.3) (2024-10-23) ### Bug Fixes * Fix XACML attribute id for system users ([#1340](#1340)) ([4257729](4257729)) * **service:** enable health-check for servicebus ([#1338](#1338)) ([480f5e3](480f5e3)) --- This PR was generated with [Release Please](https://github.com/googleapis/release-please). See [documentation](https://github.com/googleapis/release-please#release-please).
## Description This simplifies the subject attribute mapping to only use a single attribute, as multiple subject attributes are explicitly disallowed by the PDP (eg. for system users). In fact, for external use, only a single subject attribute is ever required (eg. sending the authlvl attribute is not supported, as it is the PEPs responsibility to enforce any obligations returned from the PDP). In addition, support for allowing pure Maskinporten tokens (using only consumer-claims) has been removed, as this is not officially supported in the Altinn Authorization model; only userid/pid/systemuserid will cause the PDP to resolve roles/access packages in order to match policy rules, so the only way sending organization numbers as subject claims is if the policy itself contains hard coded organization numbers, which is discouraged (should access lists for that). Note that urn:altinn:org (ie serviceowner acronym claim types) are left out, as authenticated service owners should not use the end user APIs (this would potentially leak information that we only want to make available to the end users). ## Related Issue(s) See previous PR (#1340) and [slack thread](https://digdir.slack.com/archives/C079ZFUSFMW/p1729772275391209). ## Verification - [x] **Your** code builds clean without any errors or warnings - [x] Manual testing done (required) - [x] Relevant automated test added (if you find this hard, leave it and we'll help out) <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit - **New Features** - Enhanced error handling with the introduction of an `UnreachableException` for invalid user types. - Streamlined attribute selection logic for improved performance. - **Bug Fixes** - Updated claims structure in tests to reflect recent changes, ensuring accurate validation. - **Tests** - Added a new test for exception handling. - Renamed and consolidated existing tests for clarity and maintainability. <!-- end of auto-generated comment: release notes by coderabbit.ai -->
