Hi, I have setup JOSSO2 Single Sign On using the Atricore Console, and am able to see the login page (Welcome! You're an anonymous user). However, the problem is creating the users. I have used "RDBMS Identity Source" as the Identity Source. My identity appliance consists of Identity Source (RDBMS) connected to Identity Provider (IdP). IdP connected to Service Provider (SP), SP connected to JOSSO1 resource (JOSSO1-RE), and JOSSO1-RE connected to Tomcat Execution Environment (SP1EE). The connections I have used are : RDBMS Identity Source is connected to IdP via Identity Lookup Connection. SP1 and AcmeIDP is wired with the Federated Connection. JOSSO1-RE is wired into SP1 with a Service Connection. JOSSO1-RE is connected into SP1EE by the Activation Connection. When I test the login, I get error "Invalid Authentication Information", and even after much troubleshooting, I am not able to figure out the problem. In the HOWTOPAGE "Adding Two-Factor Authentication", you explain that the Service Provider also has to be connected to an Identity Source? Do I have to do the same in my case? Isn't it enough to have only one Identity Source (In this case, my RDBMS) which is connected to the IdP, which will help the SP in authentication? Also, to add users for JOSSO, I read the article from the "Getting Started" page in josso.org, that I have to create a group "role1" and then create the users and put them in this group. Only then will the users will be created and be allowed to successfully login? This is the error I get in the atricore.log for the unsuccessful login (username used is "surentran") : Code: 2020-04-08 17:23:14,835 | INFO | qtp-347993098-40 | acmeidp | ng.builtin.LoggerAuditingHandler 33 | 117 - org.atricore.idbus.kernel.auditing.builtin - 1.4.4.SNAPSHOT | principal=surentran action=SSO outcome=FAILURE attempt=1 httpSession=id-5411b4d8-f00a-44bb-91f9-f97a8fe73afa.idbus-web-001 federatedProvider=http://192.168.121.72:8081/IDBUS/MYFIRSTIA/SP1/SAML2/MD provider=acmeidp authnCtx=urn:oasis:names:tc:SAML:2.0:ac:classes:Password remoteAddress=192.168.113.96 Please help me resolve this ASAP, as I have hit a dead end, and not sure what to do to resolve this problem.
