Administering authorization permissions

Messaging security uses role-based authorization. When a user is assigned to a role, the user is granted all of the permissions that the role contains. By administering authorization permissions, you can control user access to a bus and its resources when messaging security is switched on.

Before you begin

You can administer authorization permissions using the wsadmin tool. For more information about scripting, see Getting started with scripting. For guidance on the type of changes you may need to make to authorization permissions, refer to Planning your security requirements.

Why and when to perform this task

When a bus is created, an initial set of default authorization roles are created that allows all authenticated users who have bus connector role full access to all local destinations on the bus. However, by default only the Server group has the bus connector role. If a particular user needs to connect to the bus, the administrator must grant that user the bus connector role.

Note that by default, when security is enabled, users do not have access to a foreign bus. You need to explicitly add a specific user to the foreign bus access list. For details of the task, see Adding users and groups to foreign bus roles using the wsadmin tool.

You can make changes to authorization permissions when messaging security is enabled or disabled. Any changes that you make when security is disabled will not have any effect until security is enabled, as described in Enabling and disabling messaging security.
LDAP Registry Tip: When you specify the group authorization permissions, the group distinguished name (DN) must be used. If you specify a common name (CN) for the group name, users in that group do not have the specified authorities. For more details see Standalone Lightweight Directory Access Protocol registries.

To configure permissions, complete the following steps using the wsadmin tool:

  1. Open a wsadmin command session.
  2. Type the required command.
The following syntax is used for the commands. For details of the command properties, see the topics listed below.
variable
A variable, for which you type a value. The commands use the following variables:
  • destinationType
  • busName
  • foreignBusName
  • destinationName
  • topicSpaceName
  • topicName
  • roleName
  • userName
  • groupName
<true|false>
A choice of options, from which you type one value (that is, either true or false).

Use the commands in the topics listed below to configure the authorization permissions for a bus to meet your security requirements.
