SAML Single Sign On (SSO) into SonarQube using Bitium

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

Step 1: Setup Bitium as Identity Provider

    Follow these steps to configure Bitium as an Identity Provider using SAML 2.0 Single Sign On protocol.

  • Login as an administrator in Bitium
  • Once you have logged into your Bitium Admin portal, click on the Manage "your organization"
  • Click on Manage Apps
  • In the top right corner, click on Add More Apps. You'll see a search box, so search for ?custom_app? and add the app to your Bitium account.
  • Click Single Sign-On tab and select SAML Authentication.
  • Copy over into the following information for configuring the add-on:
      1) Entity ID
      2) Login URL
      3) Logout URL
      4) X.509 Certificate
      5) Metadata URL
  • Paste information from SP Info tab in the plugin into Bitium
  • Click Save in the application provider
  • Click Save Changes in Bitium

    • 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].
