Active Roles provides the ability to manage directory data in Microsoft Active Directory Lightweight Directory Services (AD LDS), an independent mode of Active Directory formerly known as Active Directory Application Mode (ADAM).
A running copy of the AD LDS directory service is referred to as a service instance (or, simply, instance). To use Active Roles for managing data hosted by the AD LDS directory service, you first need to register the instance that holds the data to manage.
Once an instance has been registered, the Active Roles client interfaces—Console, Web Interface and ADSI Provider—can be used to access, view and modify directory data in the application and configuration partitions found on the instance. The instances registered with Active Roles are referred to as managed AD LDS instances.
To register an AD LDS instance with Active Roles
In Server, type the fully qualified DNS name (for example, server.company.com) of the computer on which the instance is running. In LDAP port, type the number of the Lightweight Directory Access Protocol (LDAP) communication port in use by the instance (the default communication port for LDAP is 389). You can also click Select to locate and select the AD LDS instance you want to register.
If you want each Administration Service to connect to the instance in the security context of its own service account, click The service account information the Administration Service uses to log on. With this option, different Administration Services may have different levels of access to the instance (the service account of one Service may have administrative rights on the instance while the service account of another Service may not). As a result, switching from one Administration Service to another may cause Active Roles to lose access to the instance.
If you want each Administration Service to connect to the instance using the same user account, click The Windows user account information specified below and type in the user name, password, and domain name. In this way, you specify a so-called override account, thereby causing the access rights of Active Roles on the instance to be determined by the access rights of that user account (rather than by those of the service account of the Administration Service).
If you choose not to specify an override account, you should add the service account to these groups.
If you add the account to the Administrators group, you don’t need to add it to the Instances or Readers group.
Use the AD LDS ADSI Edit console to add the account to the appropriate groups prior to registering the instance with Active Roles.
After an AD LDS instance is registered, you can view or change its registration settings by using the Properties command on the object representing that instance in the Managed AD LDS Instances (ADAM) container. Thus, you can make changes to the choices that were made in Step 5 of the above procedure.
If you no longer want to manage an AD LDS instance with Active Roles, you can unregister the instance by using the Delete command on the object representing that instance in the Managed AD LDS Instances (ADAM) container. Unregistering an instance only removes the registration information from Active Roles, without making any changes to the directory data within that instance.
The application and configuration partitions found in the managed AD LDS instances are grouped together in a top-level container, thus making it easy to locate the AD LDS data. Each partition is represented by a separate container (node) so you can browse the partition tree the same way you do for an Active Directory domain.
The Active Roles console supports a wide range of administrative operations on AD LDS users, groups and other objects, so you can create, view, modify, and delete directory objects, such as users, groups and organizational units, in the managed AD LDS instances the same way you do for directory objects in Active Directory domains.
To browse the directory tree and manage AD LDS objects
In the AD LDS (ADAM) container, each directory partition is identified by a label that is composed of the name of the partition, the DNS name of the computer running the AD LDS instance that hosts the partition, and the number of the LDAP port in use by the instance.
Normally, the console only displays the application directory partitions. To view the configuration partition, switch into Raw view mode: select View | Mode, click Raw Mode, and then click OK.
You can only perform the data management tasks to which you are assigned in Active Roles. Thus, you are only shown the commands you are authorized to use and the objects you are authorized to view or modify.
In addition to access control, Active Roles provides for policy enforcement on directory data. Policies may restrict access to certain portions of directory objects, causing data entry to be limited with choice constraints, auto-generating data without the ability to modify the data, or requiring data entry. The console provides a visual indication of the data entries that are controlled by policies: the labels of such data entries are underlined on the dialog boxes so that the user can examine policy constraints by clicking a label.
To enable the creation of users in AD LDS, the administrator should first import the optional definitions of user object classes that are provided with AD LDS. These definitions are provided in importable .ldf files (ms-User.ldf, ms-InetOrgPerson.ldf, ms-UserProxy.ldf), which can be found on the computer running the AD LDS instance. Alternatively, the software designers can extend the AD LDS schema with their custom definitions of AD LDS user object classes. Details on how to extend the AD LDS schema can be found in Microsoft’s documentation that comes with AD LDS.
To add an AD LDS user to the directory
By default, an AD LDS user is enabled when the user is created. However, if you assign a new AD LDS user an inappropriate password or leave the password blank, the newly created AD LDS user account may be disabled. Thus, an AD LDS instance running on Windows Server 2003 automatically enforces any local or domain password policies that exist. If you create a new AD LDS user, and if you assign a password to that user that does not meet the requirements of the password policy that is in effect, the newly created user account will be disabled. Before you can enable the user account, you must set a password for it that meets the password policy restrictions. The instructions on how to set the password for an AD LDS user and how to enable an AD LDS user are given later in this section.
AD LDS provides default groups, which reside in the Roles container of each directory partition in AD LDS. You can create additional AD LDS groups as necessary. New groups can be created in any container.
To add an AD LDS group to the directory
You can add both AD LDS users and Windows users to the AD LDS groups that you create. For instructions, see the sub-section that follows.
