You can modify only aggregated roles; default application-specific roles cannot be modified from Shared Services. You may change any role property except the product name.
To modify aggregated roles:
Launch Shared Services Console. See Launching Shared Services Console.
Retrieve an aggregated role. See Searching for Users, Groups, Roles, and Delegated Lists.
On the General tab, edit the name and description to modify general properties of the role.
To modify role member assignments, open the Role Members tab and perform actions from step 7.a, step 7.b, or both:
Retrieve the roles to add.
Click Go to retrieve all roles.
Enter the role name in Search for Roles and click Go to retrieve a specific role. Use * (asterisk) as the wildcard in pattern searches.
From Available Roles, select one or more.
Click Add. The selected roles are listed under Assigned Roles.
From Assigned Roles, select one or more, and then click Remove to remove the selected role. Click Reset to undo your actions on this tab.
From Assigned Roles, select roles to remove.
Click Remove.
