Access control entries (ACEs) provide a mapping of user groups to containers. They are also referred to as the membership scope of a container. There are eight types of ACEs. The User or Domain, including All, membership scope requires explicit specifications of the SIP URI of the specified user and domain.


ACE Name




Explicitly identifies an individual user and overrides any other ACE. This ACE is specific to a single SIP address.



Identifies all users who are members of a specified SIP domain. This ACE is called people in <domain name> in the Communicator user interface.


Same Company

Identifies the host organization. This ACE, called People in my company in the Communicator user interface, typically resides in the Company container. By default, every user in the organization is a member of the Company container unless the user is explicitly given membership in another container.


Public Cloud

Identifies all users who belong to supported public IM service providers, which can include the MSN network of Internet services, Yahoo!®, and AOL®. Public Internet connectivity requires a separate license. This ACE is called people in public domains in the Communicator user interface.



Identifies all users from partner organizations that are federated with the host organization. This ACE is called people in domains connected to my company in the Communicator user interface.



The All ACE applies to everyone.
