Bugs Resolved

• Fixed NemLog-in private sector CPR check handling when the SubjectMatchesCPR service returns BadRequest for an invalid CPR value.
• Users now see the same inline field error as other CPR mismatch cases: CPR number does not match the user.
• The NemLog-in CPR validation response is logged separately for troubleshooting instead of sending the user to a technical error page.
• Fixed mTLS certificate conversion used by NemLog-in private sector CPR matching after the ITfoxtec.Identity update. FoxIDs now uses the ITfoxtec.Identity ToX509Certificate(includePrivateKey: true) conversion path so Windows mTLS client authentication receives a certificate with a usable private key.

This release introduces enhanced user sign-up controls, expanded SAML 2.0 encryption configuration, and updated cryptographic and database components.

Administrators can now restrict self-service user registration to specific email domains, providing greater control over who can create accounts. SAML 2.0 applications now support configurable assertion and key encryption algorithms, improving interoperability with a wider range of identity providers and service providers.

The release also improves configuration consistency by automatically updating authentication method references, cleans up related Environment Links when configurations are deleted, strengthens certificate resource handling, updates the certificate-to-JWK conversion to use the shared ECDSA implementation in ITfoxtec.Identity and includes the latest PgKeyValueDB driver.

New Features and Improvements

User Sign-up Restrictions

• Added support for restricting user sign-up in Login authentication methods to specific email domains.
• Administrators can configure a list of allowed domains for Create User.
• When domain restrictions are enabled, the sign-up flow requires the user identifier to be an email address.

Configurable SAML 2.0 Response Encryption

Added support for configurable response encryption algorithms for SAML 2.0 applications.

• Authentication response encryption now supports separate:
  • EncryptionAlgorithm
  • KeyEncryptionAlgorithm
• This enables FoxIDs to interoperate with SAML implementations that require explicit configuration of both assertion data encryption and key encryption algorithms.

Supported algorithms include:

• AES-CBC
• AES-GCM
• RSA-OAEP
• XML Encryption 1.1 RSA-OAEP

Existing configurations remain fully compatible by continuing to use the current defaults:

• AES-256-CBC for assertion data encryption
• RSA-OAEP for key encryption

Configuration Improvements

• When an authentication method is renamed, the new name is automatically updated in claim transforms, claim transform tasks, and applications that reference it in Allowed Authentication Methods.

• Environment Link cleanup

  • Related Environment Links are removed automatically.
  • Deleting an environment removes all associated Environment Link connections.
  • Deleting either the application side or the authentication method side of an Environment Link also removes the corresponding linked configuration.

Cryptography Improvements

• Updated certificate-to-JWK conversion to use the shared ECDSA implementation provided by ITfoxtec.Identity.
• Improved certificate resource handling by consistently disposing temporary certificate instances after use, reducing the risk of native handle and resource leaks during certificate validation, metadata generation, and token processing.

Dependency Updates

• Updated the PostgreSQL driver PgKeyValueDB to version 3.4.4.

Bugs Resolved

Create User

• Fixed an issue where the phone country code could be used during user creation when a phone number was not required in the Create User UI.

Summary

This release enhances SAML 2.0 security validation and interoperability by introducing configurable validation allowlists for signature algorithms and XML canonicalisation methods. These improvements provide greater flexibility when integrating with identity providers that use different signing technologies, while maintaining backward compatibility through secure default settings.

The release also resolves an issue that prevented ECDSA certificates from being used consistently across SAML 2.0 integrations, bringing SAML 2.0 certificate support in line with OpenID Connect capabilities.

New Features and Improvements

SAML 2.0 Validation Allowlists

SAML 2.0 now supports configurable validation allowlists, providing more flexible control over accepted signature and XML processing methods.

• Multiple signature validation algorithms

  • SignatureValidationAlgorithms can now contain multiple accepted signature algorithms.
  • For example, both RSA and ECDSA algorithms can be accepted simultaneously.

• Multiple XML canonicalisation methods

  • XmlCanonicalizationValidationMethods can now contain multiple accepted XML canonicalisation methods.
  • This simplifies interoperability with identity providers that use different canonicalisation standards.

• Backward compatibility

  • If no allowlist is configured, FoxIDs automatically applies secure default values.
  • Existing configurations continue to work without modification.

Bugs Resolved

ECDSA Certificate Support in SAML 2.0

• Fixed an issue that prevented externally used ECDSA certificates from being supported correctly in SAML 2.0 integrations.

This release improves the reliability and usability of logging and diagnostics in FoxIDs.

The update enhances log search behaviour for values containing hyphens, making searches more accurate and predictable. It also resolves an Application Insights log parsing issue where truncated trace messages could prevent logs from being displayed correctly. FoxIDs now handles truncated trace data gracefully, ensuring that available log entries remain accessible.

New Features and Improvements

Improved Log Search Accuracy

• Correct handling of hyphenated values
  Fixed log search behaviour for values containing hyphens, such as usernames and identifiers.

• Phrase-based matching
  Searches for values such as xxxx-yyy are now treated as a single phrase rather than separate terms, preventing unintended matches on partial values such as xxxx.

Bugs Resolved

Application Insights Log Parsing

• Graceful handling of truncated trace messages
  Fixed an issue where large trace messages stored in Application Insights could be truncated by Azure.

• Improved log viewer reliability
  Previously, truncated trace data could cause the track log view to fail. FoxIDs now handles truncated log data gracefully and displays all available log entries whenever possible.

This release improves the reliability of Environment Link logout flows and strengthens the consistency of Home Realm Discovery (HRD) configuration handling across applications and authentication methods.

The update ensures that front-channel logout requests are handled gracefully, even when the associated authentication method session has already been removed. It also resolves an issue where HRD auto-selection based on IP addresses, IP ranges, and regular expressions could stop working for applications linked to authentication methods.

Bugs Resolved

Environment Link Front-Channel Logout Reliability

• Idempotent logout handling
  Fixed a crash that could occur during Environment Link front-channel logout when the logout callback arrived after the authentication method session had already been removed.

• Improved session cleanup behaviour
  Logout requests are now handled idempotently, ensuring that delayed or repeated callbacks are processed safely without causing errors.

Home Realm Discovery (HRD) Configuration Synchronisation

• Fixed HRD auto-selection in linked applications
  Resolved an issue where HRD auto-selection based on IP addresses and IP ranges could stop working in applications linked to an authentication method.

• Complete HRD rule propagation
  Applications linked to an authentication method now correctly inherit all HRD rules when they are created or updated, including:

  • IP addresses
  • IP ranges
  • Regular expression (regex) rules

This ensures consistent Home Realm Discovery behaviour across linked configurations and prevents missing or outdated HRD settings.

Summary

This release delivers significant enhancements across federation protocols, claim transforms, authentication token handling, logging, and the Control Client user experience.

The headline feature is the addition of WS-Federation support for both authentication methods and application registrations, including interoperability with AD FS and Microsoft Entra ID. The release also improves claim transform usability and diagnostics, adds support for issuing refresh tokens from authentication methods to applications, and introduces more detailed Home Realm Discovery (HRD) trace logging.

Additional improvements ensure that the Control Client test applications remain reliable for long-term use, while NuGet package updates address known vulnerabilities and strengthen overall platform security.

New Features and Improvements

WS-Federation Support

• Added WS-Federation support for authentication methods and application registrations.
• Supports metadata import and export, SAML 1.1 and SAML 2.0 tokens, sign-in and sign-out flows, token encryption, and claims mapping.
• Compatible with AD FS and Microsoft Entra ID.

Claim Transform Enhancements

• Claim transforms now support querying users by User ID using the sub lookup claim.
• Updated descriptions and help text throughout the claim transform UI.
• Added colours, summaries, and default-expanded sections to improve usability and troubleshooting.

Authentication and Token Improvements

• Added support for exposing a refresh token from an authentication method in a refresh_token claim.
• The refresh_token claim can now be issued alongside an access_token claim to applications.

Home Realm Discovery (HRD)

User Experience Improvements

• Updated email templates to include more detailed and meaningful text.

Bugs Resolved

SAML 2.0 Certificate Management

• Fixed an issue where removing a SAML 2.0 certificate did not immediately update the UI.
• The same certificate can now be re-added immediately after removal, either by file selection or drag-and-drop.

SAML 2.0 NameID Handling

• Resolved an issue where an external SAML 2.0 NameID could be overridden by a claim transform, resulting in incorrect logout requests.
• Fixed an issue where SAML 2.0 did not correctly select an alternative identifier claim when the NameIdentifier claim was unavailable. FoxIDs now correctly falls back to UPN, Email, or Name.

This release improves logging behaviour for external API integrations, with a particular focus on SMS provider and external service diagnostics.
Instead of globally limiting all log messages to 4 KB, FoxIDs now applies response-size limits only when logging responses from external APIs, such as SMS providers.

This approach preserves detailed internal logging while still protecting the system from excessively large external API responses.

Improvements

Improved External API Response Logging

• Selective response-size limiting
  Log message size limits are no longer applied globally across all logging.

• External API response protection
  Response-size limits are now applied only when logging responses from external APIs, such as:

  • SMS providers
  • External HTTP integrations
  • Third-party services

This release expands Access Structure policies for internal users, introducing hierarchical controls for MFA enforcement, sign-in restrictions, and password policy assignment.
Administrators can now apply security and password policies through access structure nodes, with inheritance across child nodes and prioritised password policy groups.

The release also introduces a new generic Access URL SMS provider, providing flexible SMS integration through configurable API endpoints and placeholders.
In addition, SMS logging has been improved to reduce unnecessary logging, sensitive query parameters are excluded, HTTPS is now required for all SMS providers, and log message sizes are capped to improve stability and security.

New Features and Improvements

Access Structure Policies

Added Access Structure policies for internal users.

Nodes in an access structure can now:

• Require multi-factor authentication (MFA)
• Disable user sign-in
• Assign password policy groups

Policies apply to users assigned to the node and are inherited by child nodes.

Password policy group prioritisation

• Password policy groups are now prioritised according to their order in Environment Settings.
• The Control Client UI now supports reordering password policy groups to control evaluation priority.

Generic Access URL SMS Provider

Added support for a new generic Access URL SMS provider.

The provider can be configured:

• Per environment
• Globally

Configuration options include:

• Base API URL
• Query parameters with placeholders for:
  • Phone number
  • Message
  • Sender name

This enables integration with custom or third-party SMS gateway providers using simple URL-based APIs.

SMS Logging and Security Improvements

• Reduced SMS logging verbosity
  SMS provider logging has been improved to log less information by default and only include SMS message content when errors occur.

• Improved SMS log privacy
  SMS logging now avoids storing query parameters while still including phone numbers for troubleshooting purposes.

• HTTPS required for all SMS providers
  All SMS providers are now required to use HTTPS to improve transport security.

Logging Improvements

• Log message size limits
  Log messages are now limited to 4 KB, reducing excessive log payloads and improving operational stability.

This release introduces Directory Connector support, enabling FoxIDs to integrate with external authoritative user directories while maintaining internal user records.
It allows organisations to delegate authentication and password lifecycle operations to external systems such as Active Directory, while still leveraging FoxIDs for identity orchestration and claims handling.

In addition, a deployable Active Directory Directory Connector component is provided, simplifying integration with on-premises environments.
The release also strengthens security and consistency by enforcing stricter validation of enabled user identifiers in login authentication methods.

Further improvements include expanded Access Structure scalability with support for up to 2,000 nodes, enhanced visibility of certificate information in the NemLog-in template, improved master seed readiness error messages, and updated NuGet packages addressing known vulnerabilities.

⚠️ The External Login – API is now obsolete and will be phased out in a future release. It is recommended to migrate to the Directory Connector for all external authentication scenarios.

New Features and Improvements

Directory Connector

Added Directory Connector support for validating users against an external authoritative directory while maintaining internal FoxIDs users.

• Validate username and password against an external directory.
• Delegate password change and set-password operations to the external directory.
• Save a local password copy by default, allowing future transition to internal validation without forcing password resets.
• Automatically disable or delete internal users when the external directory reports changes.
• Support external directory identifiers via directoryUserId.
• Support password policy error codes from the external directory, enabling clear validation messages.
• Create or update internal users on successful authentication with identifiers, claims, and properties from the directory.
• Includes a documented API contract and sample implementation.

Active Directory Directory Connector Component

Added a deployable Active Directory Directory Connector component for Windows/IIS environments.

• Deployable as a standalone ZIP package.
• Uses static API key protection via FoxIDs Basic authentication, with optional X-FoxIDs-Api-Key support for reverse proxy scenarios.
• Supports user lookup by email, phone, or username.
• Returns directoryUserId as base64 encoded Active Directory objectGUID.
• Authenticates users by validating passwords against AD.
• Supports password change and set-password operations in AD (requires appropriate privileges).
• Returns configurable AD attributes as FoxIDs claims.
• Optional support for nested AD group claims.
• Includes a health endpoint for operational status and AD connectivity checks.
• Comprehensive documentation for configuration, IIS installation, deployment, patching, and updates.

Authentication Improvements

• Stricter user identifier validation
  Enforced stricter compliance for which user identifiers are enabled in login authentication methods, improving consistency and reducing configuration errors.

Additional Improvements

• Expanded Access Structure scalability
  Increased Access Structure capacity to support up to 2,000 nodes, enabling larger and more complex hierarchical access models.

• Improved NemLog-in template visibility
  Certificate information is now displayed in the NemLog-in template within the Control Client, improving transparency and troubleshooting.

• Improved master seed readiness error messages
  Enhanced error messages related to master seed readiness to provide clearer diagnostics and easier troubleshooting.

• Security and dependency updates
  Updated NuGet packages to address known vulnerabilities and improve overall platform security.

This release fixes an issue in the password reset flow, ensuring that the correct communication channel is selected based on user configuration.
FoxIDs now correctly respects user-specific channel restrictions when both SMS and email are available in the authentication method.

Bugs Resolved

Password reset channel selection

• Correct channel selection for password reset codes
  Fixed an issue where FoxIDs could attempt to send a password reset code via SMS even when SMS was disabled for the user.

• Improved channel prioritisation
  If the authentication method allows both SMS and email, but the user is only permitted to reset their password via either SMS or email, the permitted method is selected.
