SAML Single Sign On (SSO) into SonarQube using Google Apps/G Suite
SonarQube SAML plugin gives the ability to enable SAML Single Sign On for the SonarQube. Here we will go through a guide to configure SSO between SonarQube and GoolgeApps/G Suite. By the end of this guide, GoogleApps/G Suite users should be able to log in and register to the SonarQube Server.
You can refer the steps from the video or documentation below to configure your IDP with SonarQube.
Step 1: Set Up Google Apps/GSuite as Identity Provider
Follow these steps to set up Google Apps/GSuite as an Identity Provider:
Navigate to the Apps tab in the left menu and click on Web and mobile apps.
1.2 Add a SAML app
Click on the Add App, then select Add Custom SAML app from the dropdown to create a new SAML app.
Enter the details for your custom SAML app and click Continue.
1.3 IDP Information
On the next screen, click on Download Metadata to retrieve data needed to configure your Service Provider.
Alternatively, you can copy GSuite details like SSO URL, Entity ID and Certificate to configure the Service Provider manually.
Click Continue once you’re done.
1.4 Service Provider Details
Enter details from the Service Provider Metadata tab in the SAML SP plugin.
ACS URL
Copy and paste the ACS URL from the plugin.
Entity ID
Copy and paste the SP Entity ID/ Issuer from the plugin.
Signed Response
Check Signed Response ✓
Name ID Format
EMAIL
Click Continue once you’re done entering the details.
1.5 Attribute Mapping
Click on Add Mapping to add and select user fields in Google Directory.
Next, map them to Service Provider attributes and click Finish once done.
1.6 Turn On SSO
Go to SAML Apps again and click on OFF for everyone .
Then, select ON for everyone to activate SSO.
Note: After activating SSO, you can specify which users it applies to. For instance, if you choose organizational units, all users within that unit will be required to use SSO to access G Suite Apps. Likewise, you can choose to enforce SSO for specific groups or all users in the account.
Step 2: Configure SonarQube as Service Provider.
Fetch the Identity Provider (IdP) Details
After configuring the IdP, get its metadata to configure SonarQube as a Service Provider(SP)
Copy the following details from the IdP metadata and paste them into the corresponding text fields in the SonarQube plugin
1. IdP Entity ID
2. Login URL
3. X.509 Certificate
Save all the details.
Test Configuration
Once you have filled all the IdP details, go to Administration >>Configuration >>miniOrange SAML Support and then click on the Test Configuration tab.
It will show you the IdP login page. Enter your IdP credentials and log in.
If all the configurations are correct, it will show you the user details received from the IdP.
If the test fails, check if you have missed out any steps or try to debug through SonarQube Logs.
To be able to troubleshoot through logs, first you'll have to set a higher log level in your SonarQube application.
To do so, go to the SonarQube Dashboard >>Administration >>System.
Under the system settings, you'll find an option to change the log's level. Select DEBUG and save it. Now try to configure the plugin.
If you face any problem during configuration, go to %SONARQUBE_HOME% / logs directory.
Find and open the web.log file. Go through the logs recorded.
You'll find the stacktrace of performed actions, along with date and time information.
In order to map attributes from the Identity Provider to the application, the attribute names received in the SAML response need to be entered in their corresponding fields.
To view these attribute names, click on the Test Configuration tab in the plugin support page.
Attributes used in SonarQube Application are described briefly as below:
Login Attribute is a unique name assigned to the user to identify them uniquely within the SonarQube system. It's a required attribute.
Name Attribute is the full name of the user, to be mapped from the IdP to the SonarQube. It's a required attribute.
Email Attribute is an optional attribute and represents an email address of the user, to be mapped from the IdP to the SonarQube.
Group Attribute mapping requires the group names, in the application, to be same as the group names in the Identity Provider. Otherwise, the default SonarQube Group is assigned to the user.
Eg. To map group value Everyone from SAML response we have to paste groupName in Group Attribute field [Refer with above image].
