Single Sign-On (SSO) for Apps Using Google Apps as IDP | Google Apps SSO Login


Google Apps as IDP (Identity Provider) solution by miniOrange helps you to SSO login to your applications/websites using Google Credentials. Google Apps Single Sign-On solution can be implemented by configuring Google Apps as SAML IDP in miniOrange, where miniOrange will act as SP. Here we will go through a step-by-step guide to configure SSO login between website/application and Google Apps by considering Google Apps as IdP (Identity provider) and miniOrange as SP(Service provider).

miniOrange also acts as an identity broker for cross protocol authentication. It basically means configuring a Service Provider following a particular protocol with an Identity Provider following some different protocol like SAML,OAuth etc. Once configured successfully you will be ready to securely access your website/application using Google Apps as IDP.

Step 1: Configure Google Apps as Identity Provider (IDP) in miniOrange

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


    Follow the steps to configure Google Apps as IdP by SAML configuration.

4. Setup Multiple IDPs (Optional)

    You have a choice to set multiple IDPS for Single Application, i.e integrate multiple IDP and users can select IDP accordingly from which they want to authenticate themselves. There are three different ways to authenticate users using IDP.

  • Login using IDP selection page: It gives users an option to Select IDP from the dropdown list during login time.
  • Domain Mapping: Here we map the email domains to a particular IDP. So when the user enters the Email address with a specific domain he would be redirected to the respective IDP.
  • App Identity Provider Mapping: This feature gives users an option to select one specific IDP for their application before login.
  • Note : At once you can select either of them.



  • 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.

    Select your IDP (Identity Provider) to login

  • 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-
    Customize IDP selection login page
  1. You can customize the title of this page.
  2. Change the logo and favicon for this page.
  3. Change the background and button color for this page from admin UI.

If you have multiple IDPs and you want a certain set of users to authenticate from one IdP whereas another set of users to authenticate from another IdP, based on their email domains you can achieve this by using the following steps:- Our domain mapping feature

  • We have provided a Domain Mapping field under each IdP where admins can enter the domain eg. demo.com , example.com as shown in the screenshot below.
  • Domain Mapping for selected IDP SSO

    Lets say, there are two organisations under ADFS. One want to authenticate the users under the domain demo.com and other one with the domain example.com. For reference, We have taken the 2 organisations as two different IDPs and WordPress as SP. Follow the guides to set up ADFS and WordPress at your end.

  • Once the setup is complete you can login through your Wordpress site.
  • So a user logging in with the demo.com domain will be redirected to the first organisation under ADFS.
  • Selected IDP Login Page


  • User logging in with email address having example.com domain will be redirected to the second organisation under ADFS.
  • Different Domain IDP SSO login
    SSO Login Page for the selected domain
  • Once the user will authenticate itself through respective Organisations under ADFS, it will be redirected back to Wordpress site.

    If you have multiple IDPs (identity provider) and you want a certain application user to authenticate with one IDP and other application users with another IDP then you can achieve this by our Identity Source Feature.

  • Go to apps >> your_app >> select >>edit.
  • Edit SAML app
  • Here you will have an option called as an Identity source.
  • The dropdown list would show the list of configured IDPs (Identity providers) in miniOrange Identity Providers tab and Userstore.
  • Select one IDP you want for this application. Click on Save.
  • Select IDP from which you want to authenticate users
  • Now the users of this application would be able to authenticate only by the IDP (Identity Provider) selected from the Identity Source dropdown list.
