Question

我正在使用VBScript使用LDAP脚本在我的应用程序与OID（Oracle身份目录）之间进行身份验证。我成功地进行了身份验证。下一步涉及获取用户所属的所有组，并使用我的应用程序中的组进行映射。由于某些原因，我无法从LDAP服务器获取组信息。我知道我应该查询的属性是“groupmembership”。但我无法从此属性中获取任何值。需要任何帮助。这是我所拥有的代码片段 -

OID通常没有名为groupmembership的用户的属性（除非您自己添加了一个属性）。

如果您要查找用户所属的组，则必须对组进行第二次ldap搜索。

OID中的组具有groupOfNames或groupOfUniqueNames作为其对象类。这些对象类中的每一个都具有用于存储组成员名称的多值属性。将用户分配到组时，会将其DN添加到相应的多值属性中。在groupOfNames对象类中，此多值属性是成员，而在groupOfUniqueNames对象类中，它是uniqueMember。

如何使用VBScript从Oracle LDAP服务器（OID）获取groupmembership属性？
