Java Single Sign-On SSO
Java JWT Single Sign-On (SSO) solution by miniOrange provides secure Single Sign-On access into Java application using a single set of login credentials. This is done using JSON Web Token (JWT) tokens and it can be easily integrated with Java built in any framework or language. You can enable social login for your users to get secure access to applications using any of their existing social providers such as Facebook, Twitter, Google, or LinkedIn.
With miniOrange Java SSO, you get:
- Seamless user login experience.
- Endless customizations to your login forms and pages.
- Simplified customer or user on-boarding.
Connect with External Source of Users
miniOrange provides user authentication from various external sources, which can be Directories (like ADFS, Microsoft Active Directory, Azure AD, OpenLDAP, Google, AWS Cognito etc), Identity Providers (like Shibboleth, Ping, Okta, OneLogin, KeyCloak), Databases (like MySQL, Maria DB, PostgreSQL) and many more.
Follow the step-by-step guide given below for Java Single Sign-On (SSO):
1.Configure Java in miniOrange
In miniOrange dashboard, you can add JWT application with steps below:
- Login into miniOrange Admin Console.
- Go to Apps >> Add Application.
- In Choose Application Type click on JWT application type.
- In the next step, search for your application from the list, if your application is not found. Search for JWT App and you can set up your Application.
- Copy the Redirect-URL from the JWT Connector.
- Provide the Custom Application name of the JWT application and In the Redirect url section add the copied Redirect-URL from the JWT Connector and save the application.
- In the Primary Identity Source section, select the Identity source from where you want the users to be authenticated.
- Now, click on edit option of the JWT application which we just created.
- Copy client id, client secret and Single Sign-On Url of the application.
- Paste the client id, client secret in the client id and client secret fields of the connector and Single Sign-On Url in the Authorization Url field of the connector.
- Go to Apps and download the Certificate of the JWT application.
- Open the certificate in a text editor and paste it in the Signing Certificate field of the Connector.
- In the Application URL field add the url where you want to redirect into your application after successful authentication and click on save.
- After saving the configuration try Test Configuration.
- On the Application Url which we have previously configured you need to read the user attributes from the session variable that is sent by SSO connector and use that to login user into your application.
- You can use the following code snippet in your redirect endpoint to retrieve the attributes from the session variable.
HttpSession session = request.getSession(false);
Map jwtResponseAttributes = (Map)request.getSession().getAttribute("attributes");
- Now that the SSO Connector is configured, you're ready to use it in your application. Use the following URL as a link in your application from where you want to perform SSO:
http://<your-domain>/<application-name>/sso?action=login
2. Configure Java JWT SSO Connector
- Download miniOrange Java from here.
- Copy the jar file and paste it in WEB-INF/lib folder of your project.
- Copy the following code and paste it in web.xml file of your project.
<servlet>
<description></description>
<display-name>SSOServlet</display-name>
<servlet-name>SSOServlet</servlet-name>
<servlet-class>com.miniorange.app.servlets.SSOServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>SSOServlet</servlet-name>
<url-pattern>/sso</url-pattern>
</servlet-mapping>
</servlet-mapping>
- Create a System Environment Variable named MO_SSO_CONFIG and give it a path. Here your properties files used by connector will be stored.
- Access SSO connector from your browser with URL https://<your-domain>/<application-name>/sso.
- Register into SSO connector by providing a valid email address and password.
- After registration, log in to the dashboard using the credentials you provided during registration.
