Deploy secured applications
Before you begin
Deploying applications that have security constraints is not much different than deploying applications that don't contain any security constraints. The only difference is that you might need to assign users and groups to roles for a secured application, which requires that you have the correct active registry. To deploy a newly secured application click...
Applications | Install New Application...in the navigation panel on the left and follow the prompts. If you are installing a secured application, roles would have been defined in the application. If delegation was required in the application, RunAs roles also are defined.
One of the steps required to deploy secured applications is to assign users and groups to roles defined in the application. This task is completed as part of the step titled Map security roles to users and groups. This assignment might have already been done through an assembly tool. In that case one can confirm the mapping by going through this step. We can add new users and groups and modify existing information during this step.
If the applications support delegation, then a RunAs role is already defined in the application. If the delegation policy is set to Specified Identity (during assembly) the intermediary invokes a method using an identity setup during deployment. Use the RunAs role to specify the identity under which the downstream invocations are made. For example, if the RunAs role is assigned user "bob" and the client "alice" is invoking a servlet, with delegation set, which in turn calls the enterprise beans, then the method on the enterprise beans is invoked with "bob" as the identity. As part of the deployment process one of the steps is to assign or modify users to the RunAs roles. This step is titled "Map RunAs roles to users". Use this step to assign new users or modify existing users to RunAs roles when the delegation policy is set to Specified Identity.
Overview
These steps are common for both installing an application and modifying an existing application. If the application contains roles, you see the "Map security roles to users and groups" link during application installation and also during managing applications, as a link in the Additional properties section.
Procedure
- Click...
Applications | Install New ApplicationComplete the steps (non-security related) that are required prior to the step entitled Map security roles to users and groups.
Note: Depending upon the configuration, System Authorization Facility (SAF) configuration will take precedence.
- Assign users and groups to roles. For more information, see Assigning users and groups to roles.
- Map users to RunAs roles if RunAs roles exist in the application. For more information, see Assigning users to RunAs roles.
- Click Correct use of System Identity to specify RunAs roles if needed. Complete this action if the application has delegation set to use System Identity (applicable to enterprise beans only). System Identity uses the WAS security server ID to invoke downstream methods and should be used with caution as this ID has more privileges than other identities in terms of accessing WAS internal methods. This task is provided to make sure that the deployer is aware that the methods listed in the panel have System Identity set up for delegation and to correct them if necessary. If no changes are necessary, skip this task.
- Complete the remaining (non-security related) steps to finish installing and deploying the application.
What to do next
Once a secured application is deployed, verify that one can access the resources in the application with the correct credentials. For example, if your application has a protected Web module, make sure only the users that you assigned to the roles are able to use the application.
