我为应用服务构建了几个 OpenLDAP 服务器。两台服务器在配置方面似乎都很好,我可以使用 Apache Directory Studio 来管理这些服务器RootDN cn=admin,dc=somedomain,dc=com。并且复制也在它们之间起作用。这些是通过编译 OpenLDAP 源代码在 RHEL8 上构建的,因为不再提供 OpenLDAP 服务器包。OpenLDAP 版本是 2.4.52。
我可以通过 Directory Studio 创建 OU 和用户,并在应用程序中使用其中一个作为服务帐户进行身份验证。在这种情况下,用户是uid=svc-admin,ou=Admins,ou=People,dc=somedomain,dc=com并且 OU 如下:
- ou=Admins,ou=People,dc=somedomain,dc=com
- ou=读者,ou=人,dc=somedomain,dc=com
- ou=用户,ou=人,dc=somedomain,dc=com
现在的要求是用户svc-admin应该对上述 OU 具有写入/完全权限,因为该应用程序旨在配置新用户,并且它将使用 svc-admin 作为服务帐户写入上述 OU。它应该能够创建用户并修改他们的属性。
我创建了一个 ACL 并能够使用 ldapmodify 应用它,但是,当我作为 Apache DS 上的 svc-admin 连接到 LDAP 服务器时,我可以读取但无法修改或创建新用户。当我这样做时,我通过 Apache DS 和 shell 都得到一个错误。权限不足 - 错误 50 - 没有对 parent 的写访问权。
这是我使用的 ACL:
dn: olcDatabase={1}mdb,cn=config
changetype: modify
add: olcAccess
olcAccess: to dn.subtree="ou=People,dc=somedomain,dc=com" by dn.exact="uid=svc-admin,ou=Admins,ou=People,dc=somedomain,dc=com" write
olcAccess: to dn.subtree="ou=Users,ou=People,dc=somedomain,dc=com" by dn.exact="uid=svc-admin,ou=Admins,ou=People,dc=somedomain,dc=com" write
olcAccess: to dn.subtree="ou=Readers,ou=People,dc=somedomain,dc=com" by dn.exact="uid=svc-admin,ou=Admins,ou=People,dc=somedomain,dc=com" write
它不工作。这是我的olcDatabase={1}mdb和olcDatabase={0} 配置文件。我清理了 ACL,因为它们没有任何好处。

我该如何解决这个问题。非常感谢解决此问题的任何帮助。
