Chapter 4 Designing a Cisco Unity System with Exchange as the Message Store
Considerations for
For general information on Cisco Unity and Active Directory, see the applicable Cisco Unity Data and the Directory white paper, also at http://www.cisco.com/en/US/products/sw/voicesw/ps2237/prod_white_papers_list.html.
•The main Cisco Unity services log on by using two Active Directory accounts that the installer creates during Cisco Unity installation:
–Message store services log on by using the message store services account. These services send and receive messages on behalf of the subscriber. The account with which these services log on must have direct access to the Exchange message store where the subscribers reside.
–Directory services log on by using the directory services account. These services write to user, group, and contact objects when the objects are imported into Cisco Unity, and they write to individual subscriber properties when a subscriber or an administrator changes personal settings for the subscriber.
Each service account can be used by more than one Cisco Unity server in the same domain.
•The Cisco Unity installation, message store services, and directory services accounts require Active Directory permissions to create objects during installation and to manage the objects during regular operation. The Cisco Unity Permissions wizard grants the required permissions automatically based on options the installer chooses for the customer configuration. For a detailed explanation of the permissions required, see the Help file Permissions Granted by the Cisco Unity 5.0(1)+ Permissions Wizard at http://ciscounitytools.com/HelpFiles/PW501/PWHelpPermissionsSet_ENU.htm.
The installation and directory services accounts also require Exchange permissions. For more information, see the Help file Delegating Exchange Administrative Control for Cisco Unity 5.0(1)+ at http://ciscounitytools.com/HelpFiles/PW501/PWHelpExchange_ENU.htm.
For additional information on the Permissions wizard, see the Help file Granting Permissions with Cisco Unity 5.0(1)+ Permissions Wizard at http://ciscounitytools.com/HelpFiles/PW501/PWHelp_ENU.htm.
•The Cisco Unity directory service periodically queries the local DC and GC for changes to Active Directory data that also appears in the SQL Server database on the Cisco Unity server. If any changes are found, the directory service updates the SQL Server or MSDE database accordingly. These queries do not significantly affect the performance of the DC or GC unless a significant number of changes have been made to Active Directory user accounts.
•Cisco Unity is an Active Directory
•Active Directory Application Mode (ADAM) is not supported.
