Active Directory Federation Services
The federated server often sends parts of the requests it receives to the data sources for processing. A pushdown operation is an operation that is processed remotely. The DB2 instance that manages the federated system is referred to as the federated server, even though it acts as a client when it pushes down requests to the data sources. 14 rows · A federated server is configured to receive requests that might be partially or entirely.
Engage in Web single-sign-on SSO —based communication with another organization that also has at least one federation fedefated and, when necessary, with the employees in your own organization who need access over the Internet. Enable front end services to impersonate users sfrver infrastructure services using identity delegation. For more information, see When to Use Identity Delegation. The following sections describe some of the key decisions for determining when and where to create one or more federation cederated.
To make an informed decision regarding when to create a new federation server, you must first determine in which organization the server will reside.
The role that a federation server plays in an organization depends on whether you place the federation server in the account partner organization or servef the resource partner organization. When a federation server is placed in the corporate network of the account partner, its role is to authenticate the user credentials of browser, Web service, or identity selector clients and send security tokens to the clients.
When a federation server is placed in the corporate network of the resource feserated, its role is to authenticate users, based on a security token whaf is issued how to cook dungenous crab a federation server in the resource partner organization, or its role is to redirect token requests from configured Web applications or Web services to the account partner organization that the client belongs to.
You create federation servers in your organization whenever you want to deploy any of the following AD FS designs:. If necessary, an organization that deploys a Federated Web SSO design can configure a single federation server so that it acts in both the account partner role and in the resource partner role. In this case, the federation server may produce Security Assertion Markup Language SAML tokens, based on user accounts in its own organization, or reroute token requests to the organization, based on where the users' accounts reside.
For the Federated Web SSO design, there must be at fexerated one federation server in the account partner and at least one federation server in the resource partner. A federation server can serve out Web pages for sign-in, policy, authentication, and discovery in the same way that a federation server proxy does. The primary differences between a federation server and a federation server proxy whaf to do with what operations a federation server can perform that a federation server proxy cannot perform.
The federation server performs the cryptographic operations that produce the token. Although federation server proxies cannot produce tokens, they can be used to route or redirect the tokens to clients and, when necessary, back to the federation server. Federation servers support sfrver use of Windows Integrated Authentication for clients on the corporate network; whzt server proxies do not.
To mitigate this, consider protecting the communication channel between these servers using IPSEC or using a physically secure connection between all of these servers. For connections between fededated servers and domain controllers, consider turning on Kerberos signing and encryption. When you use either of these tools, you can select any of the following options to create a federation server.

Behavior of a portal's hosting server
When connected to a federated server as a user, any services shared with the user or a group the user is a member of can be viewed and consumed. Users see a customized view of the portal website, can use the organization's maps, apps, layers, and .

The key differences to administering a federated server are noted below. When you federate an ArcGIS Server site with a portal, the portal's security store controls all access to the server. This impacts how you access and administer the federated server. When you federate, any users, roles, and permissions that you previously configured on ArcGIS Server services are no longer valid.
Access to services is instead determined by portal members, roles, and sharing permissions. The portal also provides a viewer role, which has a limited set of privileges. The portal additionally includes a custom role that is considered a user role by the federated server. You should set up and check these permissions in your portal before you expose your federated server to end users. At the time of federation, items are automatically created in the portal for all existing ArcGIS Server web services.
These items are owned by the administrator who performs federation. After federation, ownership can be reassigned to existing portal members as desired. Any items or services added to the portal after federation are explicitly owned by the member who created them.
When federated, the ability to isolate access to the server is eliminated. For example, anyone with publisher privileges can publish to any federated server. However, you can update a federated server's security configuration to restrict administrative and publisher access.
See Fine-grained access control of federated servers below for details. When connected to a federated server as a viewer, any services shared with the viewer or a group the viewer is a member of can be viewed and consumed. Viewers see a customized view of the portal website, can use the organization's maps, apps, layers, and tools, and join groups owned by the organization. Viewers do not have privileges to create, share, or own items.
When connected to a federated server as a user, any services shared with the user or a group the user is a member of can be viewed and consumed. Users see a customized view of the portal website, can use the organization's maps, apps, layers, and tools, and join groups owned by the organization. Users can also create maps and apps, add items, share content, and create groups. Publishers can only work with services that they have created in the portal.
They cannot modify or delete other publishers' services. For example, when connected to the federated server in ArcMap , only services published by the publisher will display. Publishers have user privileges and can also perform analysis on layers in maps. Anyone with publisher privileges can publish to any federated server.
Services published to a federated server are automatically added as items in the portal. Hosted services published directly to the portal appear as items in the portal and as services on the hosting server. Administrators have user and publisher privileges, and they have permissions to all services hosted by the federated server. Administrators also have privileges to manage the portal and all of its members. A portal must have at least one administrator. However, there are no limits on how many can administer an organization.
For example, if a portal has five members, all five members can be administrators. Custom roles include a specific set of privileges defined by the administrator. For example, members with the custom role might be able to create content, but cannot create groups; they might be able to publish features, but not tiles.
In release Beginning at If a custom role is created with any administrative privileges, ArcGIS Server grants limited administrative access to members with that role. This includes rights to publish any service type directly to ArcGIS Server and the ability to view and access all services. Consider the security risks before creating a custom role for any member that includes administrative privileges. You can update a federated server to restrict publishing and administrative access.
Once updated, all portal administrators will still have administrative privileges on the server. Portal members with publisher privileges will not be granted publishing access to the server by default. A portal member must be either a member of this group or a member of the group that the item has been shared with to gain administrative access to the server.
Once you have federated a server with your portal, follow the steps below to update the server to enable this control. These will be owned by the portal member who updated the server. You can connect to ArcGIS Server Manager only if your portal account is assigned to the administrator or publisher role. You cannot log in to Manager using an account assigned to the viewer or user role. You also cannot log in using the site's primary site administrator account.
If your portal is configured with a built-in identity store or Lightweight Directory Access Protocol LDAP , you'll need to enter the user name and password of your portal account. If your portal is configured with Windows Active Directory, you may be prompted to enter your Windows credentials or be logged into Manager automatically. Follow these steps to update the shortcut path for a federated server:.
You can connect to the server in ArcGIS Desktop with any portal account, for example, accounts assigned to the viewer, user, publisher, or administrator role.
You can also connect to the server using the primary site administrator account from your ArcGIS Server site. If your portal is configured with Windows Active Directory, do not enter your Windows credentials in the wizard; click Finish , and you'll be connected to the server automatically.
If you want to connect to an ArcGIS Server site using the primary site administrator account, enter the credentials for the account.
The login page provides instructions on how to obtain this token. For more information, see Accessing the Administrator Directory on a federated server. Alternatively, you can log in using the server's primary site administrator account if you connect directly through port or You'll log in using your portal credentials.
You cannot log in using the primary site administrator account. When you designate your federated server to also act as the portal's hosting server, you provide the portal with a powerful back end. You allow portal users with at least publisher privileges to publish cached maps, feature services, and scene services tile layers, feature layers, and scene layers.
These users may not have any ArcGIS products on their computers; they may just publish the services by uploading a shapefile or a CSV file through the portal website; however, publishing through ArcMap is still an option.
All services published by portal users directly to the portal are hosted services and are placed in an ArcGIS Server folder called Hosted. This way, you can keep track of which services are hosted services and which are not. If you delete a service in the portal, it's also deleted from the server.
This is true both for services published to the federated server and hosted services published directly to the portal. Note: Prior to Hosted services were automatically deleted from the server when deleted in the portal. Service types listed in the Hosted folder differ from those in other server folders. The following table lists all supported hosted services and their updated item types:.
Tile Layer. Tile Layer and Feature Layer. Feature Layer. Imagery Layer. Scene Layer. WFS layer. Vector Tile Layer. When viewing and editing hosted service properties in Server Manager or ArcMap , there will only be a subset of the expected ArcGIS Server capabilities or operations available.
For example, some services will not display instance information in the service gallery or on the service Pooling tab in Manager. This will help ensure that you only view capabilities available through the portal. A hosting server should have sufficient storage space, CPU, and memory to accommodate the services that it will host. You should train your publishers carefully, and monitor your server metrics to avoid exceeding capacity.
Tile layers present special challenges because of the processing power that can be taken by a single large caching job or many concurrent jobs. By publishing a tile layer at large scale over an indiscriminately broad area, a single untrained portal publisher could send a very large caching job to the server that would consume portal resources for a long time. You can potentially mitigate the effect of caching jobs by running your CachingTools service in a separate ArcGIS Server cluster from the other services.
If this is not possible, you can lower the number of instances of the CachingTools service that are allowed to run at one time, thereby leaving CPU cycles available for other services.
You can also limit the number of caching jobs that can run at one time by lowering the maximum number of instances allowed for the CachingControllers service. By default, three jobs can run simultaneously. See Allocation of server resources to caching for additional details on how server resources are apportioned for caching jobs. You can unfederate a server from the portal, allowing each to continue independent of the other.
Unfederating a server site has several significant consequences and should not be done as part of routine troubleshooting. It is not easily undone and may have irreversible consequences. Removing a hosting server from the ArcGIS Enterprise portal renders existing hosted web layers unusable.
Adding the hosting server back does not return the hosted services to a usable state. Only unfederate a site if you have a clear understanding of the impact. Feedback on this topic?
