Configure and test Microsoft Entra SSO for EasySSO for Bamboo

Configure and test Microsoft Entra SSO with EasySSO for Bamboo using a test user called B.Simon. For SSO to work, you need to establish a link relationship between a Microsoft Entra user and the related user in EasySSO for Bamboo.

To configure and test Microsoft Entra SSO with EasySSO for Bamboo, perform the following steps:

  1. Configure Microsoft Entra SSO - to enable your users to use this feature.
    1. Create a Microsoft Entra test user - to test Microsoft Entra single sign-on with B.Simon.
    2. Assign the Microsoft Entra test user - to enable B.Simon to use Microsoft Entra single sign-on.
  2. Configure EasySSO for Bamboo SSO - to configure the single sign-on settings on application side.
    1. Create EasySSO for Bamboo test user - to have a counterpart of B.Simon in EasySSO for Bamboo that is linked to the Microsoft Entra representation of user.
  3. Test SSO - to verify whether the configuration works.

Configure Microsoft Entra SSO

Follow these steps to enable Microsoft Entra SSO.

  1. Sign in to the Microsoft Entra admin center as at least a Cloud Application Administrator.

  2. Browse to Identity > Applications > Enterprise applications > EasySSO for Bamboo > Single sign-on.

  3. On the Select a single sign-on method page, select SAML.

  4. On the Set up single sign-on with SAML page, click the pencil icon for Basic SAML Configuration to edit the settings.

    Edit Basic SAML Configuration

  5. On the Basic SAML Configuration section, if you wish to configure the application in IDP initiated mode, perform the following steps:

    a. In the Identifier text box, type a URL using the following pattern: https://<SERVER_BASE_URL>/plugins/servlet/easysso/saml

    b. In the Reply URL text box, type a URL using the following pattern: https://<SERVER_BASE_URL>/plugins/servlet/easysso/saml

  6. Click Set additional URLs and perform the following step if you wish to configure the application in SP initiated mode:

    In the Sign-on URL text box, type a URL using the following pattern: https://<SERVER_BASE_URL>/login.jsp

    Note

    These values are not real. Update these values with the actual Identifier, Reply URL and Sign-on URL. Contact EasySSO support team to get these values if in doubt. You can also refer to the patterns shown in the Basic SAML Configuration section.

  7. EasySSO for Bamboo application expects the SAML assertions in a specific format, which requires you to add custom attribute mappings to your SAML token attributes configuration. The following screenshot shows the list of default attributes.

  8. In addition to above, EasySSO for Bamboo application expects few more attributes to be passed back in SAML response which are shown below. These attributes are also pre populated but you can review them as per your requirements.

    Name Source Attribute
    urn:oid:0.9.2342.19200300.100.1.1 user.userprincipalname
    urn:oid:0.9.2342.19200300.100.1.3 user.mail
    urn:oid:2.16.840.1.113730.3.1.241 user.displayname
    urn:oid:2.5.4.4 user.surname
    urn:oid:2.5.4.42 user.givenname

    In case your Microsoft Entra users have sAMAccountName configured you would have to map urn:oid:0.9.2342.19200300.100.1.1 onto sAMAccountName attribute.

  9. On the Set up single sign-on with SAML page, In the SAML Signing Certificate section, click Download links for Certificate (Base64) or Federation Metadata XML options and save either or all to your computer. You will need it later to configure Bamboo EasySSO.

Create EasySSO for Bamboo test user

In this section, a user called Britta Simon is created in Bamboo. EasySSO for Bamboo supports just-in-time user provisioning, which is disabled by default. To enable user provisioning, you have to explicitly check Create user on successful login option on in the General section of EasySSO plugin configuration. If a user doesn't already exist in Bamboo, a new one is created after authentication.

However, if you do not wish to enable automatic user provisioning on the user first login, users must exist in backend User Directories the Bamboo instance make use of, such as LDAP or Atlassian Crowd.

User provisioning

Test SSO

IdP-initiated workflow

In this section, you test your Microsoft Entra single sign-on configuration using the My Apps.

When you click the EasySSO for Bamboo tile in the My Apps, you should be automatically signed in to the Bamboo instance for which you set up SSO. For more information about the My Apps, see Introduction to the My Apps.

SP-initiated workflow

In this section, you test your Microsoft Entra single sign-on configuration using Bamboo SAML Login button.

User SAML login

This scenario presumes you have enabled SAML Login Button in Look & Feel tab in your Bamboo EasySSO configuration page (see above). Open your Bamboo login URL in browser incognito mode to avoid any interference with your existing sessions. Click SAML Login button and you will get redirected to Microsoft Entra user authentication flow. Once successfully completed you will be redirected back to your Bamboo instance as authenticated user via SAML.

There's a possibility you may encounter the following screen after getting redirected back from Microsoft Entra ID.
