Most directories have a group that is used to identify certain corporate functions. These groups can be given full access to all or part of the directory. By applying the access rights to the group, you can avoid setting the access rights for each member individually. Instead, you grant users these access rights by adding them to the group.
The following sample ACI allows a group named the HRgroup full access to the ou=People branch of the directory so that they can update employee information:
aci: (targetattr="*") (version 3.0; acl "HR"; allow (all) groupdn= "ldap:///cn=HRgroup,ou=People,dc=example,dc=com";)
This example assumes that the ACI is added to the ou=People,dc=example,dc=com entry.
