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: Configuring the Identity Provider

With the plugin installed, you can move on to setting up Okta as an IDP.

    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 tab in the plugin support page.
    • 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].
