SAML Single Sign On (SSO) into Jenkins using PingOne as IDP


Jenkins SAML app gives the ability to enable SAML Single Sign-On for Jenkins. Here we will go through a guide to configure SSO between Jenkins and Ping One. By the end of this guide, Ping One users should be able to log in and register to Jenkins.

Step 1: Setup Ping One as Identity Provider

    All the information required to configure the Ping One as IDP i.e. plugin’s metadata is given in the Service Provider Info tab of the miniOrange SAML plugin.

  • Login to your Ping One environment as the administrator. Click on your ProfileAdmin.
  • Go to ApplicationsAdd ApplicationNew SAML Application.
  • Enter the application details and click Continue. Application Name, Application Description, and Category are required fields. For logos and icons, PNG is the only supported graphics format.
  • SAML Single Sign On (SSO) using Ping One Identity Provider, Fill Application Details

SAML Single Sign On (SSO) using Ping One Identity Provider, Ping One SSO Login Provide the SAML configuration details for the application.


    1.Signing. In the dropdown list, select the signing certificate you want to use.

    2.SAML Metadata. Click Download to retrieve the SAML metadata for Ping One. This supplies the Ping    One connection information to the application.

    3.Protocol Version. Select the SAML protocol version appropriate for your application.

    4.Upload Metadata. Click Choose File to upload the application’s metadata file. The entries for ACS URL    and Entity ID will then be supplied for you. If you do not upload the application metadata, you will need    to enter this information manually. When you are manually assigning an Entity ID value, the Entity ID    must be unique, unless you are assigning the Entity ID value for a private, managed application (an    application that is supplied and configured by a PingOne for Enterprise administrator, rather than by    an SP.

    5.Single Logout Endpoint. The URL to which our service will send the SAML Single Logout (SLO) request    using the Single Logout Binding Type that you select.

    6.Single Logout Response Endpoint. The URL to which your service will send the SLO Response.

    7.Single Logout Binding Type. Select the binding type (Redirect or POST) to use for SLO.

    8.Primary Verification Certificate. Click Choose File to upload the primary public verification certificate    to use for verifying the SP signatures on SLO requests and responses.

    9.Signing Algorithm. Use the default value or select the algorithm to use from the dropdown list.

       Optional:

        I.Encrypt Assertion. If selected, the assertions PingOne sends to the SP for the application will   be encrypted.

        II.Encryption Certificate: Upload the certificate from miniOrange plugin to use to encrypt the    assertions.

        III.Encryption Algorithm: Choose the algorithm to use for encrypting the assertions. We     recommend AES_256 (the default), but you can select AES_128 instead.

        IV.Transport Algorithm: The algorithm used for securely transporting the encryption key.     Currently, RSA-OAEP is the only transport algorithm supported.

        V.Force Re-authentication. If selected, users having a current, active SSO session will be    re- authenticated by the identity bridge to establish a connection to this application.

  • Click Continue to Next Step. The SSO Attribute Mapping page is displayed.
  • SAML Single Sign On  (SSO) using Ping One Identity Provider, Application Configuration
  • In the Attribute Mapping, Modify or add any attribute mappings as necessary for the application.
  • SAML Single Sign On (SSO) using Ping One Identity Provider, Attribute Mapping
  • The summary information for the application configuration is then displayed on a new page and the new SAML application is added to your My Applications list.

Step 2: Download and install the plugin in Jenkins.

    To Setup the miniorange saml SP plugin follow the path:

  • Login to your Jenkins Admin Account.
  • sso saml jenkins single sign on manage jenkins-1
  • Go to Manage Jenkins option from the left pane, and open Manage Plugins tab.
  •  sso saml jenkins single sign onmanage plugins-2
  • Go to the advanced tab and upload the hpi file.
  •  sso saml jenkins single sign onupload plugin-3
  • Follow the instructions shown on screen and restart the Jenkins.
  • sso saml jenkins single sign on install plugins-4

Step 3: Activate the plugin

  • Open Manage Jenkins and select Configure Global Security.
  • sso saml jenkins single sign on configure security-5
  • Set the Security Realm as miniorange SAML 2.0.
  • sso saml jenkins single sign on security realm-6
  • Make sure that Enable Security checkbox is checked.
SP Configurations
You can configure SP settings in IDP in 2 ways:

  • By uploading Metadata XML file
  • Manual Configuration
A. By uploading Metadata XML file

  • Click on Service Provider Metadata in SP Configuration section.
  • Metadata xml file will be downloaded.
  • Use this file to setup IDP.
B. Manual Configuration

  • To Configure SP Settings at IDP copy below URL and paste in respective fields at IDP end.
    • SP Entity ID: https://your-jenkins-domain
    • Audience URI: https://your-jenkins-domain
