Configuring the user registry bridge for federated repositories using wsadmin scripting

The user registry bridge is configured like other custom adapters. You can use the Jython or Jacl scripting language with the wsadmin scripting tool to define the user registry bridge in the federated repositories configuration.

Before you begin

Shut down WebSphere® Application Server and the wsadmin command window.

Important: If you are migrating from the stand-alone user registry on the local operating system to federated repositories on the local operating system, you must first configure the current user registry under federated repositories. For more information, see Managing the realm in a federated repository configuration.

Authorization failures might occur if users or groups are mapped to roles before migration and you use those users or groups after migrating to user registry bridge. This situation occurs because the mapping contains registry-specific information. After migration, re-map the users or groups to avoid authorization failures.

About this task

For additional information about the commands to use for this topic, see IdMgrRepositoryConfig command group for the AdminTask object.

Use the following steps to add a user registry bridge to any federated repositories configuration and to any realm that is defined within the configuration.

Procedure

  1. Start the wsadmin scripting tool.
    You can use the following command to start the wsadmin scripting tool:
    wsadmin -conntype none
  2. Use the createIdMgrCustomRepository command to add a new repository configuration for the user registry bridge.
    [AIX Solaris HP-UX Linux Windows]The following example configures a custom repository to use the com.ibm.ws.wim.adapter.urbridge.URBridge class and sets urbcustom as the identifier:
    Using Jython:
    AdminTask.createIdMgrCustomRepository('-id urbcustom 
    -adapterClassName com.ibm.ws.wim.adapter.urbridge.URBridge')
    Using Jacl:
    $AdminTask createIdMgrCustomRepository {-id urbcustom 
    -adapterClassName com.ibm.ws.wim.adapter.urbridge.URBridge}
    Avoid trouble: The user registry bridge handles requests to one user registry only. Therefore, if you define multiple repositories, each user registry implementation must have a separate instance of the user registry bridge and you must define each implementation as a separate repository with a unique repository ID..
  3. Optional: [AIX Solaris HP-UX Linux Windows]Add the necessary registry-specific properties as custom properties.
    Use the setIdMgrCustomProperty command repeatedly to add multiple properties. Use this command once per property to add multiple properties to your configuration. You must use both the name and value parameters to add the custom property for the specified repository. For example, to add a custom property of uniqueUserIdProperty, enter the following command:
    Using Jython:
    AdminTask.setIdMgrCustomProperty('-id urbcustom 
    -name uniqueUserIdProperty -value "uniqueId"')
    Using Jacl:
    $AdminTask setIdMgrCustomProperty {-id urbcustom 
    -name uniqueUserIdProperty -value "uniqueId"}

    To configure the user registry bridge to use a custom user registry, you must add the registryImplClass property and specify the exact registry implementation class. For example, specify com.xyz.abc.MyCustomRegistry as the value for the property.

    To configure the user registry bridge to use the local operating system user registry, do not specify the registryImplClass property. The user registry bridge identifies the underlying user registry implementation that is provided by WebSphere Application Server for the local operating system.

    You can set other optional properties as custom properties to define the mapping between federated repository properties and user registry properties, such as uniqueUserIdProperty, userSecurityNameProperty, userDisplayNameProperty, uniqueGroupIdProperty, groupSecurityNameProperty, and groupDisplayNameProperty. For more information about the available custom properties and their default values, see Security custom properties. To override any of these properties at the user registry level, configure the property as a custom property.
    Avoid trouble: The mapping between a federated repository property and user registry property is one-to-one. You can map only one federated repository property to a user registry property.
  4. Add a base entry to the user registry bridge configuration.
    Use the addIdMgrRepositoryBaseEntry command to specify the name of the base entry for the specified repository. For example:
    Using Jython:
    [AIX Solaris HP-UX Linux Windows]
    AdminTask.addIdMgrRepositoryBaseEntry('-id urbcustom 
    -name o=custom')
    Using Jacl:
    [AIX Solaris HP-UX Linux Windows]
    $AdminTask addIdMgrRepositoryBaseEntry {-id urbcustom 
    -name o=custom}
  5. Use the addIdMgrRealmBaseEntry command to add the base entry to the realm, which will link the realm with the repository.
    Note: The default realm name is defaultWIMFileBasedRealm. If this realm name was previously renamed, use the new realm name instead of defaultWIMFileBasedRealm. For example, to ensure consistency, you can set the realm name of the federated repository configuration to be the same name as the local operating system user registry as specified in the security.xml file. For information about how to set the realm name, see Realm configuration settings.
    Use the following command:
    Using Jython:
    [AIX Solaris HP-UX Linux Windows]
    AdminTask.addIdMgrRealmBaseEntry('-name defaultWIMFileBasedRealm 
    -baseEntry o=custom')
    Using Jacl:
    [AIX Solaris HP-UX Linux Windows]
    $AdminTask addIdMgrRealmBaseEntry {-name defaultWIMFileBasedRealm 
    -baseEntry o=custom}
  6. Save your configuration changes.
    Enter the following commands to save the new configuration and close the wsadmin scripting tool:
    Using Jython:
    AdminConfig.save()
    exit
    Using Jacl:
    $AdminConfig save
    exit
  7. Restart the application server.

Results

[AIX Solaris HP-UX Linux Windows]The following code is an example of a basic configuration in the wimconfig.xml file for a user registry bridge accessing a custom user registry:
<config:repositories adapterClassName="com.ibm.ws.wim.adapter.urbridge.URBridge" id="urbcustom">
<config:baseEntries name="o=custom"/>
 	<config:CustomProperties name="registryImplClass" value="com.ibm.registry.impl.FileRegistrySample"/>
 	<config:CustomProperties name="usersFile" value="${USER_PROPS}"/>
 	<config:CustomProperties name="groupsFile" value="${GROUP_PROPS}"/>
</config:repositories> 

[AIX Solaris HP-UX Linux Windows]In the previous example, the ${USER_PROPS} and ${GROUP_PROPS} variables are used to define the values of the custom properties.

[AIX Solaris HP-UX Linux Windows]You can use variables to define custom properties. However, these variables are resolved only in the WebSphere Application Server connected mode. For information about how to define environment variables, see Creating, editing, and deleting WebSphere variables.
