[gatein-dev] problem when config SAML2 with google and saleforce

Hi all, I'm configuring SSO for gatein 3.5 with google and salefore use SAML2 protocol. I follow by three docs: https://docs.jboss.org/author/display/GTNPORTAL35/SAML2 https://docs.jboss.org/author/display/PLINK/Picketlink+as+IDP,+Salesforce... https://docs.jboss.org/author/display/PLINK/Picketlink+as+IDP,+Google+App... When i try to login to google, it redirect to IDP (use gatein) and login success, but when redirect back to google, i meet error "google could not parse the login request" and i can't login. I see an exception on console of gatein: 16:26:01,844 ERROR [org.picketlink.identity.federation] (http-www.idp.com-127.0.0.1-8080-7) PLFED000253: Exception in processing request: java.lang.IllegalStateException: PLFED000058: KeyStoreKeyManager : Domain Alias missing for : 127.0.0.1 at org.picketlink.identity.federation.PicketLinkLoggerImpl.keyStoreMissingDomainAlias(PicketLinkLoggerImpl.java:183) at org.picketlink.identity.federation.core.impl.KeyStoreKeyManager.getValidatingKey(KeyStoreKeyManager.java:196) at org.picketlink.identity.federation.core.util.CoreConfigUtil.getValidatingKey(CoreConfigUtil.java:140) at org.picketlink.identity.federation.bindings.tomcat.idp.AbstractIDPValve.getIssuerPublicKey(AbstractIDPValve.java:683) at org.picketlink.identity.federation.bindings.tomcat.idp.AbstractIDPValve.processSAMLRequestMessage(AbstractIDPValve.java:545) at org.gatein.sso.saml.plugin.valve.PortalIDPWebBrowserSSOValve.invoke(PortalIDPWebBrowserSSOValve.java:255) [sso-saml-plugin-1.3.1.Final.jar:1.3.1.Final] at org.gatein.sso.integration.SSODelegateValve.invoke(SSODelegateValve.java:155) [sso-integration-1.3.1.Final.jar:1.3.1.Final] at org.gatein.portal.security.jboss.PortalClusteredSSOSupportValve.invoke(PortalClusteredSSOSupportValve.java:88) [exo.portal.component.web.security-jboss-3.5.7.Final-SNAPSHOT.jar:3.5.7.Final-SNAPSHOT] at org.jboss.as.web.security.SecurityContextAssociationValve.invoke(SecurityContextAssociationValve.java:153) [jboss-as-web-7.1.1.Final.jar:7.1.1.Final] at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:155) [jbossweb-7.0.13.Final.jar:] at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:102) [jbossweb-7.0.13.Final.jar:] at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:109) [jbossweb-7.0.13.Final.jar:] at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:368) [jbossweb-7.0.13.Final.jar:] at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:877) [jbossweb-7.0.13.Final.jar:] at org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:671) [jbossweb-7.0.13.Final.jar:] at org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:930) [jbossweb-7.0.13.Final.jar:] at java.lang.Thread.run(Thread.java:662) [rt.jar:1.6.0_45] *Is there any one know how to fix this problem?* Tuyen Nguyen The.
