SAML Single Sign On (SSO) into SonarQube using CA Identity

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 CA Identity. By the end of this guide, CA Identity users should be able to log in and register to the SonarQube Server.

Step 1: Setup CA Identity Manager as Identity Provider

    Follow the steps below to configure CA Identity Manager as an Identity Provider.

    miniorange img Pre-requisite:

      To configure CA Identity Manager, you need the metadata of the service provider. Go to the Add-on tab for SP Info and click on the link for metadata in Step In the new tab, SP metadata is generated. Right-click it and choose Save As to save it as an XML on your system.

    • Log in to your CA Identity service portal with the administrator account. You're going to be sent to the launchpad.
      • CA Identity sso-1
    • Go to Apps and click on add an app.
      • CA Identity sso-2
    • Scroll down in the Add App popup window and click Create a SAML SSO app
    • Fill out the information in each of the steps as given below.

      Enable SSO for Your App Using SAML

    • In Display Name, enter the name of your app and click Continue.
      • CA Identity sso-3

      Identity Provider Information

    • Download IDP Metadata. This is necessary to configure the add-on later. Click on Continue.
      • CA Identity sso-4

    • Upload SP metadata to Upload SP metadata and click Continue.
    • You can also manually enter data. The data can be found in the add- on's SP Info tab.
      • Information to be entered in CA Information to copy from the add-on
      Assertion Consumer Service URL ACS URL
      Relay State -
      Entity ID SP Entity ID
      NameID Format Email Address
      Binding POST
      Requests Signed Yes
      Certificate Download the certificate provided in SP Info tab and upload it here

      Attribute Mapping

    • Fill Attribute Mapping as per your requirement. Set Type against NameID to User Attribute and set Value as User Name or Primary Email. These attributes are used to create user in the SP.
    • Click on Continue and click Finish.
      • CA Identity sso-6

    miniorange img  Create a Rule

    • You’ll be redirected to app Dashboard. Go to Rules. A Rule defines who has the access to app. Click on add rule.
    • Enter the rule name. Click on Add Filter and select on which basis you want to assign app. You can select a department, type or title. You can add more filters according to your need. Click Continue.
    • Select the SP app you setup in Then they should have. Click Continue.
    • You can test the app by selecting a person from that department. Click Finish
      • CA Identity sso-7

Step 2: Configure SonarQube as Service Provider.

    miniorange img  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.

    miniorange img  Test Configuration

    • Once you have filled all the IdP details, click on the Test Configuration button.
    • It will take you to 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.

    miniorange img  Attribute & Group Mapping

    • 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 button in the plugin.
    • Attributes used in SonarQube Application are described briefly as below:
  1. Login Attribute is a unique name assigned to the user to identify them uniquely within the SonarQube system. It's a required attribute.

  2. Name Attribute is the full name of the user, to be mapped from the IdP to the SonarQube. It's a required attribute.

  3. Email Attribute is an optional attribute and represents an email address of the user, to be mapped from the IdP to the SonarQube.

  4. 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].
