All person and group nodes are in one or more zones. You can use zones for any
partitioning of authorities. For example, Alfresco synchronization uses zones to record from
which LDAP server users and groups have been synchronized. Zones are used to hide some groups
that provide Role Based Access Control (RBAC) role-like functionality from the administration
pages of Alfresco Share. Examples of hidden groups are the roles used in Alfresco Share and
Records Management (RM). Only users and groups in the default zone are shown for normal group
and user selection on the group administration pages. Zones cannot be managed from the
administration pages of Alfresco Share.
Zones are intended to have a tree structure defined by naming
convention. Zones are grouped into two areas: Application-related zones
and authentication-related zones.
Within a zone, a group is considered to be a root group if it is not
contained by another group in the same zone.
Alfresco uses a model for persisting people, groups, and zones. A
Person node represents each person, and an AuthorityContainer represents
groups, which can be used for other authority groupings such as roles.
AuthorityContainer and Person are sub-classes of Authority and as such can
be in any number of Zones.
