ArcGIS (SP-initiated) Integration Guide
Introduction
Use this guide to enable Service Provider (SP)-initiated Multi-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
Multi-Factor Methods – the Multi-Factor Authentication methods that will be used to access this page (if any) 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
Warning
Click Save once the configurations have been completed and before leaving the Data page to avoid losing changes
Post Authentication
 |
2. Select SAML 2.0 (SP Initiated) Assertion from the Authenticated User Redirect dropdown in the Post Authentication tab in the Web Admin
3. 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)
4. A customized post authentication page can be uploaded, but it is not required
User ID Mapping
 |
5. Select the SecureAuth IdP Property that corresponds to the directory field that contains the ArcGIS ID (Email 2)
6. 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
7. Select False from the Encode to Base64 dropdown
SAML Assertion / WS Federation
 |
8. Set the WSFed / SAML Issuer to the ArcGIS SecureAuth Realm
9. 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
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
Note
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
Warning
Click Save once the configurations have been completed and before leaving the Post Authentication page to avoid losing changes
