How to configure My Web Application as SAML Test Connector (SP) using Onelogin? - saml-2.0

Question

I have added my web application into onelogin using SAML Test Connector.
In Configuration tab I have given the following values
Recipient : http://localhost:8080/em/live/pages/samlAuth/
ACS(Consumer) URL Validator* : ^
ACS (Consumer) URL* :http://localhost:8080/ws_em/rest/accounts/consume-saml
Login URL : http://localhost:8080/ws_em/rest/accounts/produce-saml
Where http://localhost:8080/ws_em/rest/accounts/produce-saml creates an SAML Request by taking IssuerUrl, SAML EndPoint Copied From Onelogin SSO Tab and ACS url as http://localhost:8080/ws_em/rest/accounts/consume-saml.
#GET
#Produces(MediaType.APPLICATION_JSON)
#Path("/produce-saml")
public com.virima.em.core.Response SAMLAuthentication(){
com.Response resp = new com.Response();
AppSettings appSettings = new AppSettings();
appSettings.setAssertionConsumerServiceUrl(ACSUrl);
appSettings.setIssuer(IssuerUrl));
AccountSettings accSettings = new AccountSettings();
accSettings.setIdpSsoTargetUrl(IdpSsoTargetUrl);
AuthRequest authReq = new AuthRequest(appSettings,accSettings);
Map<String, String[]> parameters = request.getParameterMap();
String relayState = null;
for(String parameter : parameters.keySet()) {
if(parameter.equalsIgnoreCase("relaystate")) {
String[] values = parameters.get(parameter);
relayState = values[0];
}
}
String reqString = authReq.getSSOurl(relayState);
response.sendRedirect(reqString);
resp.setResponse(reqString);
return resp;
}
http://localhost:8080/ws_em/rest/accounts/consume-saml calls is supposed to take my SAML request and do the authentication . Here I am using the certificate generated in Onelogin SSO Tab
#GET
#Produces(MediaType.APPLICATION_JSON)
#Path("/consume-saml")
public com.onelogin.saml.Response SAMLAuthenticationResponse(){
com.onelogin.saml.Response samlResponse = null;
String certificateS ="c"; //Certificate downloaded from Onelogin SSO Tab
AccountSettings accountSettings = new AccountSettings();
accountSettings.setCertificate(certificateS);
samlResponse = new com.onelogin.saml.Response(accountSettings,request.getParameter("SAMLResponse"),request.getRequestURL().toString());
if (samlResponse.isValid()) {
// the signature of the SAML Response is valid. The source is trusted
java.io.PrintWriter writer = response.getWriter();
writer.write("OK!");
String nameId = samlResponse.getNameId();
writer.write(nameId);
writer.flush();
} else {
// the signature of the SAML Response is not valid
java.io.PrintWriter writer = response.getWriter();
writer.write("Failed\n");
writer.write(samlResponse.getError());
writer.flush();
}
return samlResponse;
}
I am getting this error
Federation Exception: Malformed URL. Please contact your
administrator.
It doesn't seem to come inside the ACS url I have inside my app.
Is there any mistakes in my configuration ? Or is there a better way to do this ?

Answer 1

ACS is Assertion Consumer Service, is the endpoint that process at the SP the SAMLResponse sent by the Identity Provider, so the http://localhost:8080/ws_em/rest/accounts/consume-saml process and validate the SAMLResponse.
Do you have verbose trace error? Malformed URL must be that the code is trying to build a URL var with a non URL string.
BTW, You are using the java-saml toolkit, but the 1.0 version instead the recommended 2.0.
I highly recommend you to use the 2.0 and before work on your integration, try to run the app example
