SAML2P Downloads

• Support for .NET 9
• Remove Support for .NET 6
• Support for Duende IdentityServer 7.1
• Added extension point into BaseResponseGenerator to modify signing certificates 

Updated the version of Duende.IdentityServer being used from 7.0.6 to 7.0.8. Also removed unneeded code from the BaseCustomSamlValidationOverride class.

Fixed a bug causing Single Logout (SLO) to use only the subject for nameID. SLO will now respect requested nameid and custom nameids

SAML tables can not exist outside the default schema

samlBuilder.AddSamlConfigurationStore(options =>
{
 options.DefaultSchema = "custom_schema",
 options.ConfigureDbContext = //..,
} 

• The SAML response containing the "NotBefore" and "NotOnOrAfter" using the wrong time, resulting in a Microsoft.IdentityModel.Tokens.SecurityTokenExpiredException : IDX10223: Lifetime validation failed. The token is expired. ValidTo (UTC): '16.02.2024 11:32:02', Current time (UTC): '16.02.2024 12:30:02'.

• Support for .Net 8.0
• Duende IdentityServer version 7.0 ( not compatible with any version below, use RSK.SAML 8.x.x )
• Support for OpenIddict version 5.1 
• We have added the ability to specify which assertion consumer services endpoint to use when generating IdentityProvider Initiated single sign-on responses.

Note the Saml+OpenIddict template uses a beta NuGet package when using MySql. We will release an updated template once a released package becomes available.

• Now supports OpenIddict Version 5

• Fixed issue with OpenIddict Session Service when logging into multiple service providers

• Support for the OpenIddict identity framework.
  • IDP
  • SP
• Allow overriding the way metadata is parsed to an XElement by overriding the ParseMetadataDocument method of the SamlMetadataParser . The default implementation removes the namespaces from the provided XML.
• Configuring SAML options using a fluent builder syntax is now easier. The SamlBuilder class now has a configure method for each concrete options class. This class returns a builder object, allowing options to be configured fluently.

• Dropped support for .Net core 3.1. 

Why is there no  Rsk.Saml version 7

For many years, we have versioned the various SAML-dependent packages independently. This process was getting too complex. So, as of version 8, all RSK.SAML package's major and minor numbers will be versioned in lockstep. Patch releases for each Nuget package will be independent. Since we had dependent packages with a major version 7, we have started this new approach from version 8.

• Resolved issue causing validation of artifact messages to throw a NotSupportedException 

• Ensured ALL SAML messages are now serialized using the new ISamlMessageXmlSerializer interface. This enables developers to take control of SAML message serialization where the defaults are insufficient for their specific use case.

• A mechanism to allow users to extend the serialization of SAML messages before they are signed. The documentation for this feature can be found here for an identity provider and here for a service provider.

• This release fixes an issue where HTTP artifact binding could not be used whilst validating a SAML message.

• Added the ability to override SAML SSO Response validation via extending the BaseCustomSamlValidationOverride class. Allows SP to be more forgiving for IDP that are not fully spec complient
• Added support for DuendeIdentityServer 6.3
• Updated SLO documentation for iterative SLO approach and combined SP and IdP-initiated SLO for a full SLO experience.

• Improved license validation error reporting

• Startup validation: The SAML component will now throw an exception if SAML middleware is not configured, preventing silent failure.

• Iterative SLO: Support the traditional iterative SLO approach to remove the need for iframes and solve strict cookie issues

• Support .NET 7

• Breaking change: ISamlSloRequestGenerator methods now take a SamlSloRequestData  as opposed to multiple parameters.
• Docs: Updated NameId docs to include steps required to return email NameId
• Docs: Add additional documentation on how to use extensibility points for SP and IdP

Rsk.Saml.IdentityProvider 6.0.2 & Rsk.Saml.DuendeIdentityServer 7.0.2:
