Configure Single Sign-On (SSO) for applications Using Google Workspace as an Identity Provider (IDP).

---

Configure Google WorkSpace as an Identity Provider (IdP) for Single Sign-On (SSO) into your applications, enabling users to authenticate themselves across multiple applications using their existing Google Workspace (GSuite) credentials without needing to sign in again.

In this setup, Google Workspace (GSuite) acts as the Identity Provider (IdP), miniOrange acts as a broker, and other applications act as Service Providers (SPs). This setup eliminates the need to manage different identities as all information is stored in a unified location - Google Workspace (GSuite), simplifying the integration process and enhancing overall security.

Additionally, miniOrange's Identity Brokering solution facilitates cross-protocol authentication, allowing the user to authenticate using Google Workspace SAML protocol and obtain access to the application, which supports SAML, OAuth and other protocols. This demonstrates how miniOrange Identity brokering enables users to authenticate across different protocols, improving the flexibility and interoperability of Single Sign-On (SSO) solutions.

Follow the easy steps given in this guide to login using Google Workspace as an Identity Provider.

1. Configure miniOrange as SP in Google Workspace

Mentioned below are steps to configure Google Workspace as IDP via SAML and OAuth configuration. Follow the steps accordingly based on your requirement (SAML or OAuth).

• SAML

2. Configure Google Workspace as an Identity Provider in miniOrange

• SAML
• OAuth

• Go to miniOrange Admin Console .
• From the left navigation bar select Identity Provider.
• Click on Add Identity Provider button.



• Select SAML. Click on Import IDP metadata.



• Choose an appropriate IDP name. Enter the URL which you have saved in the previous step from Google Workspace.
• Click on Import.

• Click Save

Test Connection

• Go to Identity Providers tab.
• Click on Select>>Test Connection option against the Identity Provider you configured.



• On entering valid Google Workspace credentials you will see a pop-up window which is shown in the below screen.



• Hence your configuration of OneLogin as an Identity Provider in miniOrange is successfully completed.

Follow the steps to configure Google Workspace as IdP by OAuth configuration.

• Go to miniOrange Admin Console.
• From the left navigation bar select Identity Provider. Select Oauth





• Enter the following values.

IdP Name	Custom Provider
IdP Display Name	Choose appropriate Name
OAuth Authorize Endpoint	https://{your-base-url}/as/authorization.oauth2
OAuth Access Token Endpoint	https://{your-base-url}/as/token.oauth2
OAuth Get User Info Endpoint (optional)	https://{your-base-url}/idp/userinfo.oauth2
Client ID	From step 1
Client secret	From step 1
Scope	openid email profile

3. Configure your app in miniOrange

• Login to miniOrange Admin Console.
• Go to Apps >> Add Application.

• SAML Application
• OAuth Application
• JWT Application

• Click on Create App under SAML.



• Search for your Application. In case you do not find your app, search for Custom SAML App.





• Get the ACS URL and SP Entity ID from your application.
• Enter the following values OR click on Import SP Metadata:

Service Provider Name	Choose appropriate name according to your choice
SP Entity ID or Issuer	Your Application Entity ID
ACS URL X.509 Certificate (optional)	Your Application Assertion Consumer Service URL
NameID format	Select urn:oasis:names:tc:SAML:1.1:nameid-format:emailAddress
Response Signed	Unchecked
Assertion Signed	Checked
Encrypted Assertion	Unchecked
Group policy	Default
Login Method	Password

• Click on Save to configure your application.
• Now to get the IDP metadata of the app configured, Go to apps >> your_app >> select >> metadata tab.



• Click on the Show Metadata details in the Information required to Authenticate via External IDPs section. Download the metadata XML file by clicking on Download Metadata button or copy the Metadata URL link.



• You need to Upload this metadata in your application.

• Click on Create App under OAuth/OIDC. Click on Open ID Connect App .



• You can add any OAuth Client app here to enable miniOrange as OAuth Server. Few popular OAuth client apps for single sign-on are Salesforce, WordPress, Joomla, Atlassian, etc.





• Enter following Values:

Client Name	Add appropriate Name
Redirect URL	Get the Redirect-URL from your OAuth Client
Description	Add if required
Group Name	Default
Policy Name	As per your Choice
Login Method	Password

• Click on Save
• Now to provide the required data to OAuth client go to the app configured i.e apps >> your_app >> select >> edit.






Note: Choose the Authorization Endpoint according to the identity source you configure.

• When you want to use you want to use miniOrange as OAuth identity server use this endpoint: https://{mycompany.domainname.com}/moas/idp/openidsso
• If you are configuring any Identity Provider in Identity Providers Menu and not using miniOrange as IDP use this endpoint: https://{mycompany.domainname.com}/broker/login/oauth{customerid}

• Click on Create App under JWT.



• Select JWT App.



• Configure the name for your application and configure Redirect-URL which tells where to send JWT response. Redirect-URL should be an endpoint on your application where you want to achieve SSO.




In case you are setting up SSO with Mobile Applications where you can't create an endpoint for Redirect or Callback URL, use below URL.

https://login.xecurify.com/moas/jwt/mobile


• Click Save
• To get the SSO link for your application, Go to Apps >> your_app >> select >> Edit.



• Then, copy the Single Sign On Url and verify SSO setup by browsing that url.



• On successful authentication, you will be redirected to configured Redirect or Callback URL with JWT token
• You will need to download a certificate from App > Manage Apps, and click Certificate link against your configured application. This certificate will be used for signature validation of JWT response.

4. Setup Multiple IDPs (Optional)

• You can configure multiple IDPs (Identity Providers) and give users the option to select the IDP of their choice to authenticate with.
  For Example - It could be multiple AD domains belonging to different departments or multiple okta organizations.

Few usecases where customers configure multiple IDPs -


• Suppose you have a product which many of your clients use and each client has their own unique IDP so you want them to SSO into your product as well using their existing IDP only. miniOrange provides a centralized way to connect with all IDPs in a very easy manner and integrate SSO into your application.
• Suppose you are providing a course to many universities, each having a unique SAML, OAuth protocol supported IDP's like Shibboleth, ADFS, CAS, etc. You can provide Single Sign-On (SSO) into your course application to all these universities by integrating with all of them using a single platform provided by miniOrange.
• This is the endpoint to call from your SAML application -

For Cloud IDP -	https://login.xecurify.com/moas/discovery?customerId=<customer_id>
For On-Premise IDP -	https://yourdomain.com/discovery?customerId=<customer_id>



• You should copy the Customer Key from admin console-> Settings -> and replace it with <customer_id> here. Once configured in SP, when you initiate the login from Service Provider, a user will be redirected to IDP Selection Page listing all IDPs configured for that account.

You can see the screenshot below of the IDP Selection Page with a list of IDPs.




Note: To view the IDP in drop-down list, go to Identity Providers tab > against your configured IDP > Select >Edit , here Enable the Show IdP to Users option.




• You can also change the look and feel of this page. Login to miniOrange Admin console. Navigate to Customization -> Branding Configuration. See the below screenshot for reference-
