If needed, encryption should be provided by SSL/TLS on transport layer. 6 comments fr2lancer commented on Oct 21, 2021 edited by marcusdacoregio HttpSessionSaml2AuthenticationRequestRepository::loadAuthenticationRequest is loaded by : And its logic like this : Depending on sslSecurityProfile setting in the ExtendedMetadata Populate trust engine for verification of SSL/TLS connections. The same applies to the underlying OpenSAML metadata bean is empty) filter will generate a new one. Default: true. will disable and remove the given profile. can be initialized at scheme://server:port/contextPath/saml/logout?local=true. trust engine based on either Section8.2.1, Metadata interoperability profile (MetaIOP) or Section8.2.2, PKIX profile is created. Examples of such settings are requirements for message signing, IDP discovery and security profiles. In case your application defines multiple local service providers, such as redirecting user to each of the SSO participants or sending a logout SOAP messages are typically used. . When to use Spring Security SAML Extension, 2.1. In samlFilter Verification of signatures is executed in two phases. In some cases . The Spring Security forums contain some previously answered with custom implementation. Spring Security SAML Extension requires as a minimum Java 1.6 and is known to work with most Java containers and application servers. by settings property responseSkew in beans WebSSOProfileConsumerImpl and SingleLogoutProfileImpl. Spring SAML doesn't enforce any limitations on which Identity Provider can be deliver messages to which of the local Service Providers. directly to the Spring configuration file and can contain additional options which are unavailable in the basic metadata document. property logMessages to true will include content of the SAML messages as part of the log. You can test IDP initialized single sign-on with URL https://idp.ssocircle.com:443/sso/saml2/jsp/idpSSOInit.jsp?metaAlias=/publicidp&spEntityID=replaceWithUniqueIdentifier, after replacing Make sure to use a Property forcePrincipalAsString can be used to change this to include the raw NameID element. In case involves usage of digital signatures. This includes at least SP-initialized Single Sign-on, Single Logout, usage of additional Sun JCE, BouncyCastle JCE). This manual describes Spring Security SAML Extension component, its uses, installation, configuration, or service providers. For remote identity Human readable name of the local SP sent with the authentication request. achieve a particular use-case such as single sign-on, single logout, discovery, artifact resolution. Would you mind to share your spring security configuration with his alternative? Typical values are. The configuration directive may for example look as follows: Critical errors raised during processing of SAML messages are generally propagated as ServletExceptions to the Java container. It is possible to customize metadata loading on a per-provider basis by adding a configured HttpClient instance to the HTTPMetadataProvider constructor. Direct SSL/TLS connections (used with HTTP-Artifact binding) require verification of the public key presented by the server. contains user interface for generation and management of metadata. Make sure to include root CA In case you use automatically generated metadata make sure to configure entityBaseURL matching the front-end URL in your metadataGeneratorFilter Time checks during processing of incoming SAML ArtifactResponse in Artifact Resolution profile. By default user gets redirected to page logout.jsp. sent requests is stored can be disabled by setting logErrors to false. What is federated Identity? How it works and its importance to For details about load balancing see Section10.1, Reverse proxies and load balancers. In my case, I removed all the code from my security configuration class, but left the annotations and added the @ImportResource as follows: Once I understand the strategy I'll open a PR to this project with this configuration. Mechanism used to deliver SAML message. A part of SAML message (an XML document) which provides facts about subject of the assertion Need The sample application by default uses log4j version 1.2 binding for SLF4J, configured with the following dependency: To view the contents of SAML messages and errors from the logs, adjust the settings of the SAMLDefaultLogger bean. The remote discovery service needs to support about the user it interacts with. Full details are available by carefully reading the Spring SAML Extension guide. Only applicable when includeScoping is set to true. org.springframework.security.saml.key.JKSKeyManager relies on a single JKS key store which contains Call is intercepted by bean samlLogoutFilter which can be configured with SAML Extension can be deployed in scenarios where multiple back-end servers process SAML requests forwarded by a reverse-proxy or a load balancer. For example for local service provider with entity alias Some IDPs allow users to stay authenticated for longer periods than this and you might need to change the default value by setting maxAuthenticationAge First, we see that, like OAuth 2.0 Login, Spring Security takes the user to a third party for performing authentication. In case your application redirect to a logout landing page). Default: empty. In the old OpenSAML and openSAML-extensions libraries it was relatively easy to add a relayState to your SP-initiated SSO. Download the Spring SAML Extension either from sources or SAML Extension ships with a default private key in the samlKeystore.jks with alias apollo Information such as means of authentication, user attributes, authorization decisions or security tokens are or configuration of time skews might be needed. Techniques passwords for private keys with alias-password value pairs. is a unique identifier within deployment of Spring SAML. Section7.1, Service provider metadata for local SP, and Section7.2, Identity provider metadata In case you want to ignore Providing an empty collection or null value to properties bindingsSSO, bindingsHoKSSO and bindingsSLO An instance of org.springframework.security.saml.userdetails.SAMLUserDetailsService can be provided to supply application-specific information about the Endpoints of filters samlEntryPoint, samlLogoutFilter and metadataDisplayFilter can be changed using the same process and without need to re-generate the metadata. In case application is deployed behind a reverse-proxy or other mechanism which makes the URL at the application server different Default: false. Inside Spring SAML this library is only used for hostname verifications and will be removed in case OpenSAML removes the dependency. to class org.springframework.security.saml.context.SAMLContextProviderLB: This setting enables the extension to correctly form all generated URLs and verify endpoints of the incoming SAML messages. is included as one of the custom filters. Spring Security SAML Extended metadata is added Entity which knows how to authenticate users and provides information it will be used as an alias to lookup a private key from the keyManager bean. SOAP binding is not available. Metadata is also available in the sample application's administration UI under Metadata information -> selected SP. It also Typically, this problem arises when the authentication request is initialized Single Logout is currently supported with HTTP-Redirect and HTTP-POST bindings. 6.1.0 Edit this Page Minimal Configuration SAML 2.0 Login Overview We start by examining how SAML 2.0 Relying Party Authentication works within Spring Security. For local entities enables requirement of signed logout requests. ISO 9001:2008 Definitions of terms used within this manual. Keys signed by certification authorities are typically provided in .p12/.pfx format (or can be converted to such using OpenSSL) and imported to Java keystore with, e.g. generated automatically during first request to the application include also filter Identifier which can be used to retrieve a complete SAML message from identity or service provider Handler is called after successful finalization of Single Logout process (reception of LogoutResponse from IDP) and determines operation to perform after logout (e.g. from the URL seen by client at least property entityBaseURL should be set to a value e.g. re-used by the caller. Default: empty. encrypt their content and in some cases for SSL/TLS Client authentication of your service provider application. ContextProvider can customized to alter behavior of the SAML Extension. The file with pre-configured metadata doesn't need to include digital signature. in Artifact resolution). at http://localhost:8080/spring-security-saml2-sample, Click Metadata Administration, login and select item with your server name from the Service providers, Note the Entity ID field, and Assertion Consumer Service URL (ACS) from the metadata XML, e.g. myAlias in https://www.myserver.com/saml_extension/saml/sso/alias/myAlias?idp=myIdp) and matching Base URL to construct SAML endpoints from, needs to be a URL with protocol, server, port and context path. For details about this profile entity IDs as keys, e.g. For local entities alias of private key used to encrypt data. For details see the Java PKI Programmer's Guide. Open web browser to the URL of the deployed application. https://server:port/yourapp or use pre-generated metadata. Signature verification can be disabled by setting property metadataTrustCheck to false in the ExtendedMetadataDelegate bean. Later in this Supported values are: EMAIL, TRANSIENT, PERSISTENT, UNSPECIFIED and X509_SUBJECT. Verification can be disabled by setting ExtendedMetadata property sslHostnameVerification Usage of HTTP-Artifact binding requires Spring SAML to make a direct SOAP call to the Identity Provider. In case you encounter XML processing exceptions please create folder jdk/jre/lib/endorsed in your mechanism. The same class is Sample application demonstrates usage of IDP discovery which is automatically invoked on access to the application root. List of all available endpoints and bindings can be found in the metadata Pressing global logout will destroy both local session and the session at IDP. The Authentication object will by default include string version of the NameID included in the SAML Assertion as itsprincipal. Metadata containing one or many identity providers can be added by providing an URL or a file. In case of invalid data (missing signature, invalid issuer, invalid issue time, invalid destination, invalid session index, invalid name ID, no user logged in) system responds with SAML 2.0 LogoutResponse with an error Status code. native SAML service providers Important code changes in 1.0.0.FINAL, 4.2.6. In order to instruct Spring SAML to keep the assertion in the original form (keep its DOM) set property releaseDOM to false on bean WebSSOProfileConsumerImpl. typically the first step for establishment of federation. Entity alias is appended to URLs of SAML endpoints and used by Spring SAML to identify the correct instance. The populateTrustEngine and populateSSLTrustEngine of interface Enter entityId configured in Section4.2.3, Generation of SP metadata in the FQDN field. keys in ExtendedMetadata and verification of metadata signatures. Support for enhanced client/proxy can be configured using property ecpEnabled of the service provider's extended metadata. a service provider and interact with identity providers using SAML 2.0 protocol. customer123 the standard URL scheme://server:port/contextPath/saml/login becomes your own service) and testing of web single sign-on and single logout. Signature is deemed trusted when the certificate used to create it is included in one The used keys can be constrained with property trustedKeys. The PKIX algorithm needs to be advised that the revocation checking is enabled. The key store for both single and multi-tenant environments. Authentication contexts IDP is allowed to use when authenticating user. typically provided to the service provider as part of single sign-on. For details about Spring SAML correctly handles SAML 2.0 LogoutRequest messages sent from the IDP and performs logout in case the message is valid. Causes of Migration. Federate) can be used with the extension. as an alias to lookup key from keyManager bean. Metadata is not required to be signed by default. Instances of interface org.springframework.security.web.authentication.logout.LogoutHandler (constructor index 1) which are responsible for destruction of user's session. Make sure that your Spring configuration for XML Signatures using property securityProfile and for SSL/TLS Signatures using SAML Extension supports multiple modes of discovery including Past indicates that validity window for checking of the value will be extended by responseSkew seconds to the past and correspondingly Alias of the default certificate is the last parameter. Setting up SAML requires configurations of multiple parties, hence making the process somewhat complex. Generation of new metadata by clicking on "Generate new service provider metadata". Copy content of the Metadata textarea to your clipboard. Value is sent to IDP and provided back to SP as part of the authentication response. this case application itself includes the SAML library in WEB-INF/lib directory of the war archive and Sets whether the IdP should refrain from interacting with the user during the authentication process. is provided in form of security assertions. SAML Extension uses SLF4J framework for logging. Configuration steps in the following chapters will be customizing beans included in for the hostConfiguration: Another common use-case is situation when artifact resolution endpoint at IDP is secured using HTTP-Basic authentication. Security profiles are defined in Extended Metadata of your local SP. . of the local SP entity to allowAll. in the contextProvider bean. resolution. Hostname verification for HTTPS connections, 12.1. For details about using Extended Metadata see Chapter7, Metadata configuration, JDK installation and include files in lib/endorsed from the latest OpenSAML archive available at System performs these steps to locate peer IDP to use: Load parameter idp of the HttpRequest object and try to locate peer IDP by the entityId. "urn:oasis:names:tc:SAML:2.0:bindings:PAOS" and "urn:oasis:names:tc:SAML:2.0:profiles:holder-of-key:SSO:browser". The time window parameters can be customized with the following settings. and initiates SAML 2.0 single sign-on with the selected IDP after clicking on the "Start single sign-on" button. applications using a custom mechanism. on your security provider implementation). within a user's HTTP session and sending of response to another back-end node would make the original request data unavailable and fail the validation. Various federation protocols such as SAML, WS-Federation, OpenID or OAuth can be used to achieve By default instance of org.springframework.security.providers.ExpiringUsernameAuthenticationToken implementation org.springframework.security.saml.context.SAMLContextProviderImpl relies on information available in the ExtendedMetadata and For remote identity providers defines an additional public key used for trust Bindings are divided to front-channel bindings which The extension can also be used in applications which are not primarily secured using Spring Security. Metadata will be automatically signed during runtime when property signMetadata is set to true. SAML is a long-trusted technology for implementing secure applications. using XML Signature or are part of the transport layer used to deliver the message like SSL/TLS. : Population of the authentication object can be further customized by overriding of the getUserDetails, getPrincipal, getEntitlements and getExpirationDate methods sample/src/main/webapp/WEB-INF/securityContext.xml Default: empty. keyStore are used as trust anchors with null value. Store the metadata file as part of your project classpath, e.g. Time checks during processing of incoming SAML LogoutResponse in Single Logout profile, Table10.4. It is possible to define configuration for multiple instances of local service providers, where each Performing Single Logout :: Spring Security Select Next, The wizard may complain that some content of metadata is not supported. https://shibboleth.net/downloads/java-opensaml/. In case ExtendedMetadata specifies property encryptionKey You can start the application from the release sample directory using command: After startup the Spring SAML sample application will be available at http://localhost:8080/spring-security-saml2-sample. Configuration of the SAML library requires beans definitions included in the Authentication can be configured by setting SSO use-cases. E.g., when initializing authentication from URL https://host:port/app/saml/login, the response Sticky session are not necessary in case only IDP-initialized SSO is used or when sessions are replicated to all nodes. Discovery helps your Service Provider determine which Identity Provider should be used for authentication of the current user. No client authentication is used when value is not specified. Keys are only used with PKIX Spring SAML), optionally define app image and press Next. Default: false. SAML2 HTTP-Redirect: Missing Signature and SigAlg parameters - GitHub CertPathBuilder and CertPathValidator by setting property validateCertPath to true on bean for manual changes in the metadata or fixing of production settings are some of those. System automatically determines which IDP to send the request to based on the currently authenticated user. Open the Spring SAML sample application at e.g. the following fields were moved from MetadataGenerator to ExtendedMetadata: customDiscoveryResponseURL -> idpDiscoveryResponseURL, removed methods signSAMLObject (moved to SAMLUtil) and getKeyInfoGeneratorName (moved to ExtendedMetadata), by default the first binding is now HTTP-POST instead of HTTP-Artifact, endpoint for Web SSO no longer includes PAOS binding, set property bindingsSSO with values "artifact", "post", "paos" for backwards compatibility, by default endpoints for Web SSO holder of key are no longer included, set property bindingsHoKSSO with values "artifact" and "post" for backwards compatibility, by default MetadataGeneratorFilter no longer sets property entityAlias to value defaultAlias, set the value manually for backwards compatibility, property forcePrincipalAsString is now set to true by default, method getAttributeByName was renamed to getAttribute, fails with ServletException instead of SAMLRuntimeException, throws ServletException on errors during acceptance of LogoutRequest instead of SAMLRuntimeException, changed error handling, throws SAMLStatusException which is handled by Filter, logged and sends a SAML Response, throws SAMLException instead of SAMLRuntimeException on missing data in context, new property includeAllAttributes, set to true for original behavior, throws SAMLException instead of CredentialExpiredException on check of response issue instant and assertion issue instant, Table3.1. Once populated context is made available to all components participating You can limit certificates used to perform the verification by setting property metadataTrustedKeys of the ExtendedMetadataDelegate bean. some of Spring SAML features will be unavailable. done through interface org.springframework.security.saml.key.KeyManager. module saml2-core was renamed to core, jar and maven artifact names stay the same, module saml2-sample was renamed to sample, jar and maven artifact names stay the same, module src was renamed to docs, jar and maven artifact names stay the same, file saml2-sample/src/main/resources/security/securityContext.xml was moved to sample/src/main/webapp/WEB-INF/securityContext.xml, administration part of the UI is now secured with username/password, updated initialization of ParserPool to disable defer node expansion, HttpClient in ArtifactResolution was made thread safe, added new failure handler (failureRedirectHandler), MetadataGenerator bean now demonstrates usage of ExtendedMetadata, FilesystemMetadataProvider was replaced with ResourceBackedMetadataProvider, file sample/src/main/resources/security/idp.xml was moved to sample/src/main/resources/metadata/idp.xml, throws SAMLException instead of CredentialExpiredException on check of artifact response issue instant, storage is now cleared on successful message reception, new mandatory property KeyManager (autowired), generated metadata is no longer signed by default (enable in ExtendedMetadata.signMetadata) and has disabled IDP discovery (enable in ExtendedMetadata.includeDiscovery). identity providers. Validation of messages can fail when internal clocks of the IDP and SP machines are not synchronized. You can instruct system to use both samlEntryPoint Please send your pull requests directly to GitHub and preferably also open issue in Jira. It is recommended that content of the exceptions is not displayed to end users, both for security and user experience reasons. Table10.1. URLs of endpoints, information about supported bindings, identifiers and In case the URL doesn't contain any alias part the default service provider please see Chapter4, Quick start guide. The other option of using the SAML library is deploying it as a Processing of SAML messages and assertions is often limited to a specific time window which e.g. This can be the case for example when using only IDP-Initialized single sign-on.
