OpenLDAP 组：如何创建具有成员和成员Uid 属性的组对象？

我刚刚在 CentOS 8 中安装并配置了 OpenLDAP 2.4，现在我正在创建组及其成员以供将来使用。

这些未来用途之一将是 LDAP + PAM 集成，这就是为什么我希望我的组在 posixGroup objectClass 中具有 memberUid 属性，该属性在 OpenLDAP 附带的 nis.schema 文件中定义：

objectclass ( 1.3.6.1.1.1.2.2 NAME 'posixGroup'
    DESC 'Abstraction of a group of accounts'
    SUP top STRUCTURAL
    MUST ( cn $ gidNumber )
    MAY ( userPassword $ memberUid $ description ) )

但我也想使用 groupOfNames objectClass 中的成员属性，该属性在 core.schema 中定义：

objectclass ( 2.5.6.9 NAME 'groupOfNames'
    DESC 'RFC2256: a group of names (DNs)'
    SUP top STRUCTURAL
    MUST ( member $ cn )
    MAY ( businessCategory $ seeAlso $ owner $ ou $ o $ description ) )

但是如果我尝试同时使用这两个对象类，我会得到一个 LDAP_OBJECT_CLASS_VIOLATION，因为它们都是 STRUCTURAL（事实上，我相信不久前 posixGroup 是 AUXILIARY）。

如何在不改变其原始规范的情况下使用这两个对象类？

有没有其他选择？我可以使用“member”属性或 posixGroup 以外的其他 objectClass 将 LDAP 与 PAM 集成吗？或者是否有另一个 AUXILIARY 且具有“member”属性的 objectClass？

成员属性对于我未来的需求非常重要，但我只打算使用 posixGroup 进行 PAM 集成。

提前致谢。

您将需要使用在RFC2703bis与 RFC2703 又名 nis.schema 相反。

下面是一个适合用 来添加的宽 ldif ldapadd，不过我担心您仍在使用 slapd.conf 而不是 slapd-config。（可能需要进行一些修改，以允许在 automountkey 之类的东西上进行 RFC2703bis 中未包含的子字符串匹配，因为我很懒，喜欢子字符串匹配和从实时配置中提取）。
