With virtual data views, you can define local virtual groups, and use them though ACIs. You can also rely on existing groups defined on backend servers. You can transform the groups from an LDAP directory to appear in the virtual namespace by using DN mapping. You can also transform all member DNs by using attribute value renaming.
With a join data view, you can join two static groups from two different LDAP backends, as long as there are no member naming conflicts. You can also create a read-only virtual group, by using an ACI on the uniquemember attribute, for example.
Directory Proxy Server server uses groups in the area of ACIs only. The ACI engine can reference both static and dynamic groups by using the groupdn keyword.
Virtual ACIs support both static and dynamic groups. However, the isMemberOf feature is not supported. Due to the severe performance impact, nested groups are also not supported.
With dynamic groups, attribute value renaming does not apply to the value of the dynamic group, because this value is an LDAP URL and is therefore not DN syntax. In other words, if a dynamic group value contains a DN, the DN part is not renamed.
