When using Active Directory to authenticate users, you can use a public key infrastructure (PKI)-based client certificate authentication to secure access to ArcGIS Server.
To use Integrated Windows Authentication and client certificate authentication, you must use ArcGIS Web Adaptor (IIS) deployed to the Microsoft IIS web server. You cannot use ArcGIS Web Adaptor (Java Platform) to perform Integrated Authentication. For instructions on how to install and configure ArcGIS Web Adaptor (IIS) with your ArcGIS Server site, see the ArcGIS Web Adaptor (IIS) Installation Guide.
Note:
If you want to federate an ArcGIS Server site with a portal and want to use Active Directory and client certificate authentication with the server, you must disable client certificate authentication on the ArcGIS Server site and enable anonymous access before federating it with the portal. Although it may sound counterintuitive, this is necessary so that your site is free to federate with the portal and read the portal's users and roles. You can then configure Active Directory and client certificate with the portal.
Configure a server with Active Directory
See the following sections to configure a server with Active Directory.
Configure ArcGIS Server security to use Active Directory users and roles
To support Integrated Windows Authentication, configure ArcGIS Server to retrieve users and roles from a Windows Active Directory server.
- Open Manager and sign in as the primary site administrator. If you need help with this step, see Log in to Manager.
You must use the primary site administrator account.
- Click Security > Settings.
- Click the Edit button
next to Configuration Settings. - On the User and Role Management page, choose the Users and roles in an existing enterprise system (LDAP or Windows Domain) option and click Next.
- On the Enterprise Store Type page, choose the Windows Domain option and click Next.
- On the Windows Domain Credentials page, provide the credentials for an account that has permissions to determine the groups in which users reside. Click Next.
Note:
It is recommended that you specify an account with a password that does not expire. If this is not possible, you'll need to repeat the steps in this section each time the password is changed.
- On the Authentication Tier page, choose Web Tier.
- Review the summary of your selections. Click Finish to apply and save the security configuration.
Review users and roles
After configuring an Active Directory domain as the user and role store, review the users and roles to ensure they were retrieved correctly. To add, edit, or delete users and roles, you must use the tools available on the Active Directory server.
- In Manager, click Security > Users.
- Verify users have been retrieved as expected from the Windows domain server.
If Active Directory has multiple domains, users from the domain that the GIS server machine belongs to are displayed.
- To view users from other domains, provide the search string [domain name]\ in the Find User field and click the Search button
. - Click Roles to review roles retrieved from the Windows domain server.
If Active Directory has multiple domains, roles from the domain that the GIS server machine belongs to are displayed.
- To view roles from other domains, provide the search string [domain name]\ in the Find Role field and click the Search button .
- Verify the roles have been retrieved as expected.
Configure administrator and publisher privileges for Active Directory users
Out of the box, ArcGIS Server only allows the primary site administrator access to the server. If you'll be using Active Directory users to administer ArcGIS Server or publish services, you must follow the steps below.
- In ArcGIS Server Manager, click the Security tab and open the Users page.
- Using the Find User tool, locate the user to whom you want to assign administrator or publisher privileges. Review the roles of which this user is a member and choose the role that will be assigned administrator or publisher privileges.
- Open the Roles page and use the Find Role tool to locate the role chosen in the previous step.
- Click the Edit button next to the role.
- For the Role Type parameter, choose either Publisher or Administrator.
- Click Save to apply your changes.
Install and enable Active Directory Client Certificate Mapping Authentication
Active Directory Client Certificate Mapping is not available in the default installation of IIS. You must install and enable the feature.

- Start Internet Information Services (IIS) Manager.
- In the Connections node, click the name of your web server.
- Double-click Authentication in the Features View window.
- Verify that Active Directory Client Certificate Authentication is displayed.
If the feature is not displayed or unavailable, you may need to restart your web server to complete the installation of the Active Directory Client Certificate Authentication feature.
- Double-click Active Directory Client Certificate Authentication and choose Enable in the Actions window.
A message appears indicating that SSL must be enabled to use Active Directory Client Certificate Authentication. You'll address this in the next section.
Configure ArcGIS Web Adaptor to require SSL and client certificates
Complete the following steps to configure ArcGIS Web Adaptor to require SSL and client certificates:
- Start Internet Information Services (IIS) Manager.
- Expand the Connections node and select your ArcGIS Web Adaptor site.
- Double-click Authentication in the Features View window.
