Set default policy set bindings

We can set provider and client default policy set bindings that are used as the global security default policy set bindings. The specified global security default bindings apply to all Web services unless the bindings are overridden at the attachment point, at the server, or at a security domain.

You must first install and configure an appserver. After the appserver is installed, install a JAX-WS application onto the server. Now, we are ready to attach a policy set to the Web service application. We can define and manage general service provider and client policy set bindings for the Web service resource by using the admin console.

Policy set bindings for servers

After you understand policy set bindings, then it is easier to understand how the default bindings are used.

Policy set bindings contain platform-specific information, such as keystore, authentication information or persistent information that is required by a policy set attachment. A policy set attachment is a policy set that is attached to an application resource. In WAS V7.0, there are two types of bindings, general bindings and application specific bindings.

There are two types of general bindings...

• general service provider bindings
• general service client bindings

Configure one or more general service provider bindings and one or more general service client bindings and then use them across a range of policy sets. Additionally, we can re-use these general bindings across applications and for trust service attachments.

To define and manage general bindings...

Services | Policy sets | General provider policy set bindings

...or...

Services | Policy sets | General client policy set bindings

The general service provider and client bindings have independent settings that we can customize to meet the needs of the environment.

Create application specific bindings

These bindings are specific to and defined by to the characteristics of the defined policy. Application specific bindings are capable of providing configuration for advanced policy requirements, such as multiple signatures; however...

• These bindings are only reusable within an application
• Have limited reuse across policy sets

To assign application specific bindings to an application for service providers...

Applications | Applications Types | WebSphere enterprise apps | application_name | Service provider policy sets and bindings

Select a Web service resource with an attached policy and click...

Assign Binding | New Application Specific Binding

To assign application specific bindings to an application for service clients...

Applications | Applications Types | WebSphere enterprise applications | application_name | Service client policy sets and bindings

Select a Web services resource with an attached policy and click...

Assign Binding | New Application Specific Binding

We can additionally assign application specific bindings for service providers or service clients using the admin console and click...

Services | Service providers | application_name

...or...

Services | Service clients | application_name | Web services resource with an attached policy

...and assign the bindings.

To learn more about general bindings or application specific bindings, read about defining and managing policy set bindings.

Default policy set bindings

In WAS Version 7.0, the security model is enhanced to a domain-centric security model instead of a server-based security model. The configuration of the default global security (cell) level and default server level bindings has also changed in this version of WAS ND. In the WAS V6.1 Feature Pack for Web Services, we can configure one set of default bindings for the cell and optionally configure one set of default bindings for each server. In V7.0, we can configure one or more general service provider bindings and one or more general service client bindings. After we have configured general bindings, we can specify which of these bindings is the global default binding. You can also optionally specify general bindings that are used as the default for an appserver or a security domain. trns

General service provider and client bindings are not linked to a particular policy set, and they provide configuration information that we can reuse across multiple applications. We can create and manage general provider and client policy set bindings and then select one of each binding type to use as the default for an appserver. Setting the server default bindings is useful if we want the services that are deployed to a server to share binding configuration. We can also share binding configuration by either assigning the binding to each application that is deployed to the server or by setting default bindings for a security domain and assigning the security domain to one or more servers.

We can specify default bindings for the service provider or client that are used at the global security (cell) level, for a security domain, for a particular server. The default bindings are used in the absence of an overriding binding specified at a lower scope.

The following list is the order of precedence from lowest to highest that the appserver uses to determine which default bindings to use:

1. Server level default
2. Security domain level default
3. Global security (cell) default

The sample general bindings that are provided with the product are initially set as the global security (cell) default bindings.

The default service provider binding and the default service client bindings are used when no application specific bindings or trust service bindings are assigned to a policy set attachment. For trust service attachments, the default bindings are used when no trust specific bindings are assigned. If we do not want to use the provided Provider sample as the default service provider binding, we can select an existing general provider binding or create a new general provider binding to meet the business needs. Likewise, if we do not want to use the provided Client sample as the default service client binding, we can select an existing general client binding or create a new general client binding.

To specify the global security (cell) default bindings...

Services | Policy sets | Default policy set bindings

For environments with multiple security domains, we can optionally choose the general provider and general client bindings to use as the default bindings for a domain.

In addition to choosing default bindings for the global security (cell), we can also choose the general provider and general client bindings to use as the default bindings for a server. This is only necessary to use different default bindings for a particular server than those used by the other servers in the security domain or cell. To choose the default bindings for a server from the admin console, click...

Servers | Server Types | WebSphere application servers | server_name | Security | Default policy set bindings

If we do not choose a general binding as the default for a server, the default bindings for the domain in which the server resides is used. If we do not choose a binding as the default for a domain, the default bindings for the global security (cell) are used. You must choose a default service provider and default service client bindings for the cell.

The general bindings that are included with WAS are initially set as the global security (cell) default bindings. We cannot delete a binding used as part of any policy set attachment or specified as the default binding for the server, a domain, or the cell. To learn more about defining default bindings for a server, see the server default bindings documentation.

Depending on the assigned security role when security is enabled, we might not have access to text entry fields or buttons to create or edit configuration data.

 

Set default policy set bindings

1. Open the admin console.

2. To set global security default policy set bindings, select...
   Services | Policy sets | Default policy set bindings

   

3. Select the default service provider binding. The default service provider binding is used as the default for policy set attachments unless the provider or client binding is overridden at the attachment point, at the server, or at a security domain. The default setting is Provider sample.

4. Select the default service client binding. If we specify a default service client binding, the selected binding overrides the default bindings specified for the cell or the security domain to which the server is deployed. The default setting is Client sample.

5. If multiple security domains are enabled, we can view the default provider bindings and the default client bindings for each security domain that is defined in the security domain default bindings collection. We can select the security domain name link to access the domain and select different default bindings. Additionally, we can select the default provider binding links or the default client binding links to access the default bindings and select different default binding settings.

6. Click Apply to apply selected bindings as the global default bindings.

7. Click Save to save the changes to the master configuration.

8. (optional) For a V6.1 application, we can specify server V6.1 default policy set bindings. To set these bindings, select...

   Services | Policy sets | Default policy set bindings | V6.1 default policy set bindings

Mixed-version environment

If we have an application that contains one or more application specific bindings that are configured at the WAS V6.1 level, this application is a V6.1 application. If we have applications that are deployed to V 6.1 servers within the V7.0 appserver environment or we have V6.1 applications that are deployed to V7.0 application servers, we can specify V6.1 default policy set bindings for the cell. These bindings are used for both client and provider policy set attachments within V6.1 applications and attachments to service applications that are deployed to a V6.1 server. Additionally, these default bindings are used for V6.1 attachments unless they are overridden at the attachment point by an application specific binding or a V6.1 server default binding. We can upgrade V6.1 bindings to WAS V7.0 bindings for by using upgradeBindings command using wsadmin, if the V6.1 application is not installed on WAS V6.1. mixv

 

Results

We have defined the global security (cell) default policy set bindings and domain default policy set bindings, if applicable.

 

Example

Suppose that you do not want to use the provided general provider binding, Provider sample, as the default service provider binding. To take advantage of existing bindings, we can copy and modify the Provider sample to meet the business needs. This example assumes that the server environment has SecurityDomain1 and SecurityDomain2 defined.

1. Copy and modify the provided Provider sample general service provider binding. Click...

   Services | Policy sets | General provider policy set bindings. Select Provider sample | copy

   Name the new general provider binding, MyServiceProviderbinding, and provide a description for the new binding.

2. Copy and modify the provided Client sample general service client binding. Click...

   Services | Policy sets | General client policy set bindings | Client sample | copy

   Name the new general client binding, MyServiceClientbinding, and provide a description for the new binding.

3. To specify the default policy set bindings for the global security (cell) and for the domains, click...

   Services | Policy sets | Default policy set bindings

   Select MyServiceProviderbinding as the default service provider binding, and select MyClientProviderbinding as the default service client binding.

4. Click Apply and Save to save the changes to the master configuration.

Assigning a domain default binding is optional. Generally, you assign domain default policy set bindings only when you want the servers in the domain to use different default bindings than the rest of the cell. In this example, suppose we have defined another general provider binding, MyServiceProviderbinding2, and you want to specify this binding as the domain default binding for the SecurityDomain1 domain.

1. From the security domain default bindings collection click...
   SecurityDomain1 | Default policy set bindings

   From this page, we can select MyServiceProviderbinding2 as the service provider domain default binding.

2. Click Apply and Save to save the changes to the master configuration.
