In this task, you perform feature-level access control, a powerful tool that enables or disables client functionality. You create a new instant messaging role and corresponding policy that limits the instant messaging functionality to the basic features. Users assigned to this new role are not able to join conference rooms, send polls, or perform any of the other advanced instant messaging tasks.
Access Manager uses the Instant Messaging Service and the Presence Service to manage the Instant Messaging policy. The Instant Messaging Service contains the policy rules for communicating with others, as well as the ability to chat, exchange files, join conferences, send alerts, and more. The Presence Service contains the policy rules for determining the ability of users to share their presence with others, as well as to access, manage, or publish one's presence.
Use a completely new web browser to start Access Manager.
For example, http://wireless.map.beta.com/amconsole.
If you are using Internet Explorer for the Portal Server desktop and Communications Express, start Mozilla or Firefox.

The new roles and policies have been created. Next you assign Tina to this new Role and note the effect on her Instant Messaging client.
Choose Roles from the View drop-down menu in the left pane of the Access Manager console.
Click on the properties arrow to the right of the IM Limited User role.
The IM Limited User pane appears.
In the right pane, choose Users from the View drop-down menu.
Click Add on the right pane.
Type Tina in the User ID field and click Next.
Select the check box next to Tina's name and click the Finish button.
You have assigned Tina the Instant Messaging Limited User Role, so she has limited access to Instant Messaging.
Duncan initially has kathy and robert in his Instant Messaging buddy list. The user tina has not yet been added. You can click the Start button from the same Instant Messenger window you used to start kathy. If you start Tina's Instant Messenger, notice that her window has very limited Instant Messaging functionality. This type of provisioning is feature-level provisioning that involves defining roles and policies for these roles. Changing the policy has the effect of removing or adding functionality to the client itself. You can experiment changing the policy and restarting Tina's client to observe the effect. You can also apply the appropriate role to others and see its effect as you start Instant Messaging as those users.
