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.
About this task
When a bus is created, an initial set of default
authorization roles is created that allows all authenticated users
who have the bus connector role full access to all local destinations
on the bus. By default only the Server group has 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:
- Open a wsadmin command session.
Note: You open
a wsadmin command session from within Qshell. For more information,
see the topic
"Configure Qshell to run WebSphere® Application Server scripts".
- 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.
