Issue in enabling SSO2 for WSO2 server
<p>I'm configuring SSO for EMM from :
<a href="https://docs.wso2.com/display/EMM201/General+Server+Configurations" rel="nofollow noreferrer">https://docs.wso2.com/display/EMM201/General+Server+Configurations</a></p>

<p>And enabling SSO2 for WSO2 server from : <a href="https://docs.wso2.com/display/IS500/Enabling+SSO+for+WSO2+Servers#EnablingSSOforWSO2Servers-ConfiguringWSO2GovernanceRegistry" rel="nofollow noreferrer">https://docs.wso2.com/display/IS500/Enabling+SSO+for+WSO2+Servers#EnablingSSOforWSO2Servers-ConfiguringWSO2GovernanceRegistry</a></p>

<p>I've downloaded latest versions of:
WSO2 Application Server - 5.3.0
WSO2 Enterprise Service Bus - 4.9.0
WSO2 Governance Registry - 5.1.0
WSO2 Identity Server - 5.1.0</p>

<p>I followed steps but I think documentation is not updated and when I try access the Application Server: <a href="https://localhost:9444/carbon/" rel="nofollow noreferrer">https://localhost:9444/carbon/</a> on browser I'm redirected to the Identity Server for authentication, but once I give credentials it gives following error</p>

<p><strong>Command Prompt</strong>
ERROR {org.wso2.carbon.identity.sso.saml.processors.SP
InitSSOAuthnRequestProcessor} -  ALERT: Invalid Assertion Consumer URL value '<a href="https://172.20.1.171:9444/acs" rel="nofollow noreferrer">https://172.20.1.171:9444/acs</a>' in the AuthnRequest message from  the issuer 'carbonServer'. Possibly an attempt for a spoofing attack.</p>

<p><strong>Browser</strong></p>

<p>SAML 2.0 based Single Sign-On</p>

<p>Error when processing the authentication request!
Please try login again.</p>
