Assigning Roles to Users and Groups 
Prerequisites
The administrator role is assigned to you.
Procedure
The following screen appears.

You can use the search function with the wild card '*' to find a user or group. You can also use the navigation buttons at the bottom of the list.
The screen in which you can assign roles to users or groups appears. On the left, you can see the attributes of the user or group if they have been maintained in the corporate LDAP directory. On the top right, you can see the roles that are already assigned to the user or group. On the bottom right, you can see all the roles in the system.

The role is added to the list of roles assigned to the user or group.
The role is removed from the list of roles assigned to the user or group.
You cannot remove roles that have been assigned to the user indirectly. For example, if a role was assigned to the group that contains the user, you cannot remove this role from the user's roles.

You can also configure screen reader support for users with visual impairment by selecting Screen Reader Support.
Result
You have assigned roles to a user or group.
When the user logs on, he or she will see the top-level navigation and portal pages defined in the roles assigned to him or her.
