DRA supports several different types of environments, including the following installations:
Managed and trusted domains
Microsoft Exchange support
Departmental support through managed subtrees
Multiple Administration servers
DRA lets you securely administer account and resource objects and Microsoft Exchange mailboxes from multiple managed domains. You can manage Microsoft Windows domains as well as multiple subtrees from specific Microsoft Windows domains. You can also perform the following administration tasks on objects in trusted domains:
View objects in trusted domains
Add accounts from trusted domains to groups in your managed domains
For more information about configuring managed and trusted domains, see the Administrator Guide for Directory Resource Administrator and Exchange Administrator.
DRA lets you manage Microsoft Exchange Server mailboxes as you manage the associated user accounts, contacts, and groups. You can implement many integrated Microsoft Exchange management features across your enterprise, including the following functions:
Automatically create, move, and delete mailbox stores when managing accounts
Automatically generate email addresses based on account naming conventions
Delegate administration of specific mailbox properties, such as mailbox security settings
DRA supports and extends your security model. By integrating Microsoft Exchange management into your DRA workflow, you save time and money with streamlined administrative processes. For more information about securely managing Microsoft Exchange mailboxes and implementing Microsoft Exchange policy, see the Administrator Guide for Directory Resource Administrator and Exchange Administrator.
Departmental support lets you manage multiple subtrees of specific Microsoft Windows domains. By managing a subtree, you can use DRA to secure a department or division within a larger corporate domain. Departmental support also limits your licensing requirements to only those objects you manage in the subtree.
For more information about implementing departmental support, see the Administrator Guide for Directory Resource Administrator and Exchange Administrator.
You can install multiple Administration servers across your managed domain. Called a Multi-Master Set (MMS), these servers help distribute administration loads and provide fault tolerance within a site. Each MMS consists of one primary Administration server and multiple secondary Administration servers.
For more information about Administration servers, see the Administrator Guide for Directory Resource Administrator and Exchange Administrator. For more information about implementing an MMS, see Section 5.0, Installing DRA in Complex Environments.
