Hi There, I am trying to achieve SAML SSO with Salesforce and GLUU using below documentation - https://www.gluu.org/docs/integrate/salesforce-sso/ I have gone through step-wise configuration and completed Salesforce configurations. Then, downloaded Metadata from it and uploaded to GLUU GUI using 'File' upload option. Thus, Completed adding Trust relationships. Now, While performing SP-Init SSO from Salesforce, I am getting error as below - Error Message - Message did not meet security requirements When checked idp-process.log, i got my hand over this details - ``` 06:45:45.187 - WARN [org.opensaml.common.binding.security.BaseSAMLSimpleSignatureSecurityPolicyRule:195] - Simple signature validation (with no request-derived credentials) failed 06:45:45.187 - WARN [org.opensaml.common.binding.security.BaseSAMLSimpleSignatureSecurityPolicyRule:138] - Validation of request simple signature failed for context issuer: https://<My_Domain>.my.salesforce.com 06:45:45.193 - WARN [edu.internet2.middleware.shibboleth.idp.profile.saml2.SSOProfileHandler:406] - Message did not meet security requirements org.opensaml.ws.security.SecurityPolicyException: Validation of request simple signature failed for context issuer at org.opensaml.common.binding.security.BaseSAMLSimpleSignatureSecurityPolicyRule.doEvaluate(BaseSAMLSimpleSignatureSecurityPolicyRule.java:139) ~[opensaml-2.6.6.jar:na] at org.opensaml.common.binding.security.BaseSAMLSimpleSignatureSecurityPolicyRule.evaluate(BaseSAMLSimpleSignatureSecurityPolicyRule.java:103) ~[opensaml-2.6.6.jar:na] at org.opensaml.ws.security.provider.BasicSecurityPolicy.evaluate(BasicSecurityPolicy.java:51) ~[openws-1.5.6.jar:na] at org.opensaml.ws.message.decoder.BaseMessageDecoder.processSecurityPolicy(BaseMessageDecoder.java:132) ~[openws-1.5.6.jar:na] at org.opensaml.ws.message.decoder.BaseMessageDecoder.decode(BaseMessageDecoder.java:83) ~[openws-1.5.6.jar:na] at org.opensaml.saml2.binding.decoding.BaseSAML2MessageDecoder.decode(BaseSAML2MessageDecoder.java:70) ~[opensaml-2.6.6.jar:na] at edu.internet2.middleware.shibboleth.idp.profile.saml2.SSOProfileHandler.decodeRequest(SSOProfileHandler.java:386) [shibboleth-identityprovider-2.4.5.jar:na] at edu.internet2.middleware.shibboleth.idp.profile.saml2.SSOProfileHandler.performAuthentication(SSOProfileHandler.java:211) [shibboleth-identityprovider-2.4.5.jar:na] at edu.internet2.middleware.shibboleth.idp.profile.saml2.SSOProfileHandler.processRequest(SSOProfileHandler.java:189) [shibboleth-identityprovider-2.4.5.jar:na] at edu.internet2.middleware.shibboleth.idp.profile.saml2.SSOProfileHandler.processRequest(SSOProfileHandler.java:90) [shibboleth-identityprovider-2.4.5.jar:na] at edu.internet2.middleware.shibboleth.common.profile.ProfileRequestDispatcherServlet.service(ProfileRequestDispatcherServlet.java:83) [shibboleth-common-1.4.5.jar:na] at javax.servlet.http.HttpServlet.service(HttpServlet.java:731) [servlet-api.jar:na] at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:303) [catalina.jar:7.0.65] ``` Could you please let me know here what is going wrong ?
