Azure Active Directory (AD)

Overview

This document is designed to assist with the setup of SAML federation between Nile, leveraging Okta as a Service Provider (SP), and Azure Active Directory (AD) as the Identity Provider (IdP).

Requirements

Administrator rights to the Nile Customer Portal.

Administrator rights to Azure AD.

The same Nile Portal administrator needs to be a user in Azure AD.

MFA needs to be disabled on the Nile Customer Portal once the IdP is set up.

Enterprise Application Setup

2. Click the portal menu icon in the top left and select “Azure Active Directory

3. In the left pane, click “Enterprise applications” under “Manage

4. Click “New application”, on the “Enterprise applications” page

5. On the “Browse Azure AD Gallery”, click “Create your own application

6. In the “What’s the name of your app?” field, enter Nile-Okta or a preferred name for the application and select “Integrate any other application you don’t find in the gallery (Non-gallery)”, and click “Create

7. Within the application (The example application is titled “Nile-Okta), click on “Assign users and groups” to add users/groups

8. Click “Add user/group” to go to the Assignment page.

9. Select user(s) to assign to the application. Then, click “Assign”:

10. Click “Single sign-on” in the left menu, and then click “SAML

11. On the “SAML-based Sign-On” page, click on Edit in the “Basic SAML Configuration” section

12. On the “Basic SAML Configuration” page, enter temporary values for Identifier (Entity ID) and Reply URL (Assertion Consumer Service URL) to generate the certificate for download.

Click on Save to save the changes.
After Azure AD is made an identity provider in the next section, the actual values for Identifier and Reply URL could be updated.

13. Next, click on Edit in the ‘Attributes & Claims’ section:

14. Edit each claim one by one as follows:
  1. Click on the user.mail claim line to open it for editing and delete the namespace URI, change the Name to ‘mail’ then Save:


  2. Similarly edit user.givenname by deleting the namespace URI and renaming givenname to firstName, and click Save:


  3. Edit user.userprinciplename by deleting the namespace URI and click Save:


  4. Edit user.surname by deleting the namespace URI and renaming surname to lastName, and click Save:


  5. Add a new claim for the mobile attribute, and click Save:


  6. Add a new claim for the displayName attribute, and click Save:


  7. Add a group claim for the memberOf attribute as illustrated, and click Save:

15. Download the ‘SAML Signing Certificate’ (to be uploaded later to the Nile Portal when adding Azure AD as a provider):

16. Note down the Azure AD Identifier and the Login URL (to be used on the Nile Portal provider setup):

The two values are provided as illustration examples only, not meant for deployment:
  Azure AD Identifier: https://sts.windows.net/f8b44d9b-778d-47da-9391-6249440b17a9/
  Login URL: https://login.microsoftonline.com/f8b44d9b-778d-47da-9391-6249440b17a9/saml2

16. Note down the Azure AD Identifier and the Login URL (to be used on the Nile Portal provider setup):

17. To be done after completing the next section:

Update the ‘Identifier’ and ‘reply URL’ in the ‘Basic SAML Configuration’ section of the Nile-Okta app from the metadata.xml file downloaded after completing the Nile Portal provider set up in the next section.

Nile Portal Identity Provider Setup

1. Login to the Nile Portal (https://www.nile-global.cloud) as an administrator.
Note: it is assumed that the administrator credentials belong to a domain in Azure AD. This domain would already be an Allowed domain on the Nile Portal.

2. Go to Settings -> Global Settings -> Identity, and click on ADD A NEW PROVIDER:

3. Fill up the fields in the new provider window as follows:

Name: An appropriate string to name the provider.
IdP Issuer URI: Azure AD SAML app Identifier noted in step 15 of the previous section.
IdP SSO URL: Azure AD SAML app Login URL noted in step 15 of the previous section.
Destination URL: Azure AD SAML app Login URL noted in step 15 of the previous section.
SELECT CERTIFICATE: Upload the ‘SAML signing certificate downloaded in step 14.

4. Click the SUBMIT button to save the changes and add the new Azure AD provider

5. Click the down arrow at the far right of the newly created provider line to show the details:

6. Click the METADATA button to download the file. Then open it with a text editor and search for the ‘entityID’ and ‘Location’ strings.
The entityID and Location strings should be set aside and used to complete the Azure AD enterprise app set up as per the previous section step 16.

For illustration purposes only (values used in this example):
  entityID: https://www.okta.com/saml2/service-provider/spgjwkzhfeuahqteldnj
  Location: https://login.u1.nile-global.cloud/sso/saml2/0oa73hod48vo12OIa5d7

Note:
The Azure AD provider setup is completed for SSO users to gain Internet access after signing-in using their AD credentials.

Group Mapping

The group mapping is used to map a designated Azure AD admin group to the Nile Portal Administrator group. A Group rule needed to be added in the following steps.

The example that follows maps an AD ‘NileMonitor’ group to the Nile Portal Monitor Admin group, and an AD ‘NileAdmin’ group to the Nile Portal Administrator group:

7. Click the Group Rules tab, and on that page click the ADD GROUP MAPPING button:

8. Enter the following mapping as illustrated to add the ‘memberOf’ attribute:

9. Click the ADD GROUP RULE button to display the ADD rule form:

10. Add two group rules to map AD users members of two AD groups (NileAdmin and NileMonitor in this example) to the Nile Portal Administrator and Monitor groups respectively, by evaluating the ‘memberOf’ attribute value coming in the SAML assertion from Azure AD:

Name: An appropriate rule name
Mapping Value: Azure AD Group object ID
Assigned groups: Select the appropriate Nile group from the dropdown list

11. Click the SAVE button to save each rule:

12. Activate the two rules by clicking on the INACTIVE button to change the state to ACTIVE:

13. Go back to the enterprise app (Nile-Okta) created on Azure AD to edit the ‘Basic SAML Configuration’:

14. Click on Edit to replace the temporary values of Entity ID and Reply URL with the values of entityID and Location collected earlier in step 6:

15. Click the Save button to save the changes. Azure AD enterprise application (Nile-Okta) setup is completed.
