Introduction

Use this guide to enable Service Provider (SP)-initiated 2-Factor Authentication and Single Sign-on (SSO) access via SAML to ArcGIS.

Prerequisites

1. Have an ArcGIS account

2. Create a New Realm for the ArcGIS integration

3. Configure the following tabs in the Web Admin before configuring the Post Authentication tab:

  • Overview – the description of the realm and SMTP connections must be defined
  • Data – an enterprise directory must be integrated with SecureAuth IdP
  • Workflow – the way in which users will access this application must be defined
  • Registration Methods – the SSO Authentication method that will be used to access this page must be defined

SecureAuth IdP Configuration Steps
Data

 

1. In the Profile Fields section, map the directory field that contains the user's ArcGIS ID to the SecureAuth IdP Property

For example, add the ArcGIS ID Field to the Email 2 Property if it is not already contained somewhere else

Click Save once the configurations have been completed and before leaving the Data page to avoid losing changes

Workflow

 

2. In the SAML 2.0 Service Provider section, provide the SP Start URL to enable SSO and to redirect users appropriately to access ArcGIS

For example, the SP Start URL would be https://[company].maps.arcgis.com

Click Save once the configurations have been completed and before leaving the Workflow page to avoid losing changes

Post Authentication

 

3. Select SAML 2.0 (SP Initiated) Assertion Page from the Authenticated User Redirect dropdown in the Post Authentication tab in the Web Admin

4. An unalterable URL will be auto-populated in the Redirect To field, which will append to the domain name and realm number in the address bar (Authorized/SAML20SPInit.aspx)

5. A customized post authentication page can be uploaded, but it is not required

User ID Mapping

 

6. Select the SecureAuth IdP Property that corresponds to the directory field that contains the ArcGIS ID (Email 2)

7. Select urn:oasis:names:tc:SAML:1.1:nameid-format:unspecified from the Name ID Format dropdown (default)

Select a different option if ArcGIS requires it, which the SP will provide

8. Select False from the Encode to Base64 dropdown

SAML Assertion / WS Federation

 

9. Set the WSFed / SAML Issuer to the ArcGIS SecureAuth Realm

10. Set the SAML Offset Minutes to make up for time differences between devices

11. Set the SAML Valid Hours to limit for how long the SAML assertion is valid

No configuration is required for the WSFed Reply To / SAML Target URL, SAML Consumer URL, SAML Recipient, or SAML Audience fields

 

12. Leave the Signing Cert Serial Number as the default value, unless there is a third-party certificate being used for the SAML assertion

If using a third-party certificate, click Select Certificate and choose the appropriate certificate

13. Download the Assertion Signing Certificate, which is used in the ArcGIS Configuration Steps

14. Provide the Domain in order to Download the Metadata File that will be sent to the ArcGIS SecureAuth Realm

15. Download the Metadata File

Click Save once the configurations have been completed and before leaving the Post Authentication page to avoid losing changes

ArcGIS Configuration Steps

 

1. Log into the portal website as an Administrator and navigate to My Organization > Edit Settings > Security

2. Within the Enterprise Logins section, click Set Identity Provider

Set Identity Provider

 

3. Enter SecureAuthIdP as the Enterprise Identity Provider  Name

4. Select the option for users to join the organization – either Automatically or Upon invitation from an administrator (i.e. after accounts are added to the portal)

5. Select File as the source type of the Metadata for the Enterprise Identity Provider

6. Click Choose File and browse to the Metadata File previously downloaded from the SecureAuth IdP Web Admin (step 15)

7. Click Update Identity Provider to upload the Metadata File to the ArcGIS SecureAuth Realm
