红帽全球峰会第 2 章 使用宏访问控制说明
宏访问控制指令(ACI)可让您自动执行 LDAP 条目可区分名称(DN)或其部分并减少 ACI 的数量。
2.1. 宏访问控制指令示例

下图显示了带有后缀 dc=hostedCompany1,dc=example,dc=com 和 dc=hostedCompany2,dc=example,dc=com 的目录树，其中包含子域的重复模式。每个子域具有与 ou=groups,ou=people 条目相同的结构。目录树使用宏访问控制指令(ACI)来减少 ACI 总数。
在目录树中应用的 ACI 也具有重复模式。例如，以下 ACI 位于 dc=hostedCompany1,dc=example,dc=com 节点上，并将 DomainAdmins 组的访问权限授予该树中的任何条目：
aci: (targetattr="*")(targetfilter=(objectClass=nsManagedDomain))
(version 3.0; acl "Domain access"; allow (read,search)
groupdn="ldap:///cn=DomainAdmins,ou=Groups,dc=hostedCompany1,dc=example,dc=com";)
aci: (targetattr="*")(targetfilter=(objectClass=nsManagedDomain))
(version 3.0; acl "Domain access"; allow (read,search)
groupdn="ldap:///cn=DomainAdmins,ou=Groups,dc=hostedCompany1,dc=example,dc=com";)图 2.1. 宏 ACI 示例的目录树
以下 ACI 在 groupdn 关键字中显示 DN 的不同部分：
-
dc=hostedCompany1,dc=example,dc=com节点包含以下 ACI：
aci: (targetattr="*")(targetfilter=(objectClass=nsManagedDomain))
(version 3.0; acl "Domain access"; allow (read,search)
groupdn="ldap:///cn=DomainAdmins,ou=Groups,dc=hostedCompany1,dc=example,dc=com";)
aci: (targetattr="*")(targetfilter=(objectClass=nsManagedDomain))
(version 3.0; acl "Domain access"; allow (read,search)
groupdn="ldap:///cn=DomainAdmins,ou=Groups,dc=hostedCompany1,dc=example,dc=com";)-
dc=subdomain1,dc=hostedCompany1,dc=example,dc=com节点包含以下 ACI：
aci: (targetattr="*")(targetfilter=(objectClass=nsManagedDomain))
(version 3.0; acl "Domain access"; allow (read,search)
groupdn="ldap:///cn=DomainAdmins,ou=Groups,dc=subdomain1,dc=hostedCompany1,dc=example,dc=com";)
aci: (targetattr="*")(targetfilter=(objectClass=nsManagedDomain))
(version 3.0; acl "Domain access"; allow (read,search)
groupdn="ldap:///cn=DomainAdmins,ou=Groups,dc=subdomain1,dc=hostedCompany1,dc=example,dc=com";)-
dc=hostedCompany2,dc=example,dc=com节点包含以下 ACI：
aci: (targetattr="*")(targetfilter=(objectClass=nsManagedDomain))
(version 3.0; acl "Domain access"; allow (read,search)
groupdn="ldap:///cn=DomainAdmins,ou=Groups,dc=hostedCompany2,dc=example,dc=com";)
aci: (targetattr="*")(targetfilter=(objectClass=nsManagedDomain))
(version 3.0; acl "Domain access"; allow (read,search)
groupdn="ldap:///cn=DomainAdmins,ou=Groups,dc=hostedCompany2,dc=example,dc=com";)-
dc=subdomain1,dc=hostedCompany2,dc=example,dc=com节点包含以下 ACI：
aci: (targetattr="*")(targetfilter=(objectClass=nsManagedDomain))
(version 3.0; acl "Domain access"; allow (read,search)
groupdn="ldap:///cn=DomainAdmins,ou=Groups,dc=subdomain1,dc=hostedCompany2,dc=example,dc=com";)
aci: (targetattr="*")(targetfilter=(objectClass=nsManagedDomain))
(version 3.0; acl "Domain access"; allow (read,search)
groupdn="ldap:///cn=DomainAdmins,ou=Groups,dc=subdomain1,dc=hostedCompany2,dc=example,dc=com";)使用宏替换重复模式的多个 ACI。例如，要将以上 ACI 减少为一，请使用以下宏：
aci: (target="ldap:///ou=Groups,($dn),dc=example,dc=com")
(targetattr="*")(targetfilter=(objectClass=nsManagedDomain))
(version 3.0; acl "Domain access"; allow (read,search)
groupdn="ldap:///cn=DomainAdmins,ou=Groups,[$dn],dc=example,dc=com";)
aci: (target="ldap:///ou=Groups,($dn),dc=example,dc=com")
(targetattr="*")(targetfilter=(objectClass=nsManagedDomain))
(version 3.0; acl "Domain access"; allow (read,search)
groupdn="ldap:///cn=DomainAdmins,ou=Groups,[$dn],dc=example,dc=com";)
