SAML Single Sign On (SSO) into SonarQube using Okta
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 Okta. By the end of this guide, Okta 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: Setup Okta as
Identity Provider
Follow the steps below to configure Okta as an Identity Provider
Configuring
Okta as IdP
Log into Okta Admin Console. For developer account, switch to
Classic UI to configure app.
Go to the Application from the left menu and then click on Create
App Integration.
Select SAML 2.0 as Sign on method.
Click on Create.
In General Settings, enter App Name and click on Next.
In SAML Settings, enter the following:
Single Sign On URL
Enter ACS (AssertionConsumerService) URL from the
Service Provider info tab of the module.
Audience URI (SP Entity ID)
Enter SP Entity ID / Issuer from the Service Provider info (or
SP Information) tab of the module.
Default Relay State
Enter Relay State from the Service Provider info tab of the
module.
Name ID Format
Select E-Mail Address as a Name Id from dropdown list.
Application Username
Okta username.
Configure Attribute Statements and Group Attribute Statement (Optional).
For Name, enter "firstName" and select user.firstName from the value
dropdown.
For Name, enter "lastName" and select user.lastName from the value
dropdown.
For Name, enter "Email" and select user.email from the value dropdown.
For Name, enter "groups" and select Matches regex from the Filter
dropdown and enter ".*"
Assigning
Groups/People
After creating and configuring the app go to the Assignment Tab in Okta.
Here we select the peoples and groups you want to give access to log in through this app. Assign
this to the people/group you would to give access to.
After assigning the people/groups to your app, go to Sign On tab.
Click on View Setup Instructions to get the SAML Login URL (Single Sign
on URL), Single Logout URL, IDP Entity ID and X.509 Certificate.
You will need this to configure the Service Provider.
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].
