The ArcGIS Security Provider

When you register Essentials with Portal for ArcGIS or ArcGIS Online in the Post Installer, the Post Installer creates an ArcGIS-type security provider that you can use to secure your sites. If Essentials is registered with Portal for ArcGIS, end users can sign in using the credentials that they use to sign in to Portal for ArcGIS. Portal for ArcGIS performs the authentication. If Essentials is registered with ArcGIS Online, end users can sign in using the credentials that they use to sign in to ArcGIS Online. ArcGIS Online performs the authentication.

If you carried forward an existing ArcGIS Online security provider when you upgraded to Essentials 4.2 or newer, an ArcGIS security provider appears in place of the ArcGIS Online security provider in Manager. The ArcGIS security provider will use the permissions that you configured before 4.2. For more information, see Upgrading.

You cannot create additional ArcGIS security providers—there is at most one. If the Windows sign-in method is configured in the Post Installer, then Manager does not have an ArcGIS security provider.

ArcGIS Users and Roles

The ArcGIS security provider allows you to apply permissions to the following types of users and roles:

User: Permissions that you set for a particular Portal for ArcGIS or ArcGIS Online user only apply to that user.
All Users: Permissions that you set for all Portal for ArcGIS or ArcGIS Online users apply to all users who authenticate using their Portal for ArcGIS credentials.

If you make your site accessible to Everyone (public) from your ArcGIS Online account, any user with an ArcGIS Online account can potentially access your site. To learn how to protect access to your site, see Permissions.
ArcGIS Group: Permissions that you set for a particular Portal for ArcGIS or ArcGIS Online group apply to all the users in that group.
ArcGIS Organization: Permissions that you set for a particular Portal for ArcGIS or ArcGIS Online organization apply to all the users that belong to that organization.
ArcGIS Organization Role: Permissions that you set for a particular Portal for ArcGIS or ArcGIS Online organization role apply to all the users with that role.

Security Provider and Permission Names

The security provider's default name, and the user and role names that appear on Manager's Permissions page, depend on whether Essentials is registered with Portal for ArcGIS or with ArcGIS Online:

Portal for ArcGIS: The security provider is named after your portal by default. The user and role names start with the name of your portal.

For example, if the portal name configured in Portal for ArcGIS is My Portal, the security provider is called My Portal, and the users and roles are My Portal- ArcGIS Group, My Portal- All Users, and so on.
ArcGIS Online: The names depend on the URL that is configured for the sign-in method in the Post Installer:
- Main ArcGIS Online URL: If the main ArcGIS Online URL (www.arcgis.com) is configured, the security provider's default name is ArcGIS Online. The user and role names start with ArcGIS Online, for example, ArcGIS Online - ArcGIS Group, ArcGIS Online - All Users, and so on.
- Organization URL: If the URL for your organization's ArcGIS Online portal is configured, the security provider is named after your organization's ArcGIS Online portal by default. The user and role names start with the name of the portal.
  
  For example, if the portal is named My Portal in ArcGIS Online, the security provider is called My Portal, and the users and roles are My Portal- ArcGIS Group, My Portal- All Users, and so on.

Configure the ArcGIS Security Provider

To configure the ArcGIS security provider:

Make sure that the ArcGIS security provider is enabled.

The ArcGIS security provider is enabled by default.
If you want, edit the security provider to change the name to something that is more meaningful to end users.
Configure permissions using the ArcGIS users and roles in each site that you want to secure using the ArcGIS security provider.
