   Table 1. Policy Details

   Field	Description
   Policy Name	Enter an appropriate policy name. This name cannot be duplicated across the system. This field is mandatory.
   normal/override	Enables you to specify an override policy. When override is selected, the access permissions in the policy override the access permissions in existing policies. This feature can be used with Add Validity Period to create temporary access policies that override existing policies.

   Recursive	The default recursive setting specifies that the policy will also be applied to all sub-queues; you can also specify a non-recursive path.
   Description	(Optional) Describe the purpose of the policy.

   Add Validity Period	Specify a start and end time for the policy.

   Table 2. Allow Conditions

   Select Group	Specify the groups to which this policy applies. To designate a group as an Administrator, select the Delegate Admin check box. Administrators can edit or delete the policy, and can also create child policies based on the original policy. The public group contains all users, so granting access to the public group grants access to all users.
   Select User	Specify the users to which this policy applies. To designate a user as an Administrator, select the Delegate Admin check box. Administrators can edit or delete the policy, and can also create child policies based on the original policy.
