带有子结果的LDAP查询

我一直在敲打我的脑袋已经有一段时间了,无法让它发挥作用。我有一个LDAP查询我确实在AD用户和计算机上工作,但不知道如何在C#中以编程方式进行。

以下是我的LDAP查询在AD工具中正常工作:(memberOf = CN = AccRght,OU = Groups,OU = P,OU = Server,DC = mydomain,DC = com)(objectCategory = user)(objectClass) =用户)(L =城)

我已使用此代码获取用户帐户以获取CN = AccRght的成员,但我没有成功限制属于特定城市的用户。

public StringCollection GetGroupMembers(string strDomain, string strGroup)
{
    StringCollection groupMemebers = new StringCollection();
    try
    {
        DirectoryEntry ent = new DirectoryEntry("LDAP://DC=" + strDomain + ",DC=com");
        DirectorySearcher srch = new DirectorySearcher("(CN=" + strGroup + ")");
        SearchResultCollection coll = srch.FindAll();
        foreach (SearchResult rs in coll)
        {
            ResultPropertyCollection resultPropColl = rs.Properties;
            foreach( Object memberColl in resultPropColl["member"])
            {
                DirectoryEntry gpMemberEntry = new DirectoryEntry("LDAP://" + memberColl);
                System.DirectoryServices.PropertyCollection userProps = gpMemberEntry.Properties;
                object obVal = userProps["sAMAccountName"].Value;
                if (null != obVal)
                {
                    groupMemebers.Add(obVal.ToString());
                }
            }
        }
    }
    catch (Exception ex)
    {
        Console.Write(ex.Message);
    }
    return groupMemebers;
}

感谢您的帮助!

如果您实际上正在寻找递归枚举组成员的方法,可能需要使用memberof的递归版本(您可以使用(memberof:1.2.840.113556.1.4.1941:=(cn=Group1,OU=groupsOU,DC=x)))语法实现)。

嗯,基本上你只需要将你在工具中使用的LDAP过滤器传输到DirectorySearcher中 - 就像这样:

public StringCollection GetGroupMembers(string strDomain, string strGroup)
{
    StringCollection groupMemebers = new StringCollection();

    try
    {
        DirectoryEntry ent = new DirectoryEntry("LDAP://DC=" + strDomain + ",DC=com");

        DirectorySearcher srch = new DirectorySearcher();

        // build the LDAP filter from your (CN=strGroup) part that you had
        // in the constructor, plus that filter you used in the AD tool
        // to "AND" those together, use the LDAP filter syntax:
        //  (&(condition1)(condition2))  
        srch.Filter = string.Format("(&(CN={0})(memberOf=CN=AccRght,OU=Groups,OU=P,OU=Server,DC=mydomain,DC=com)(objectCategory=user)(objectClass=user)(l=City))", strGroup);

        SearchResultCollection coll = srch.FindAll();

        foreach (SearchResult rs in coll)
        {
            ResultPropertyCollection resultPropColl = rs.Properties;

            foreach( Object memberColl in resultPropColl["member"])
            {
                DirectoryEntry gpMemberEntry = new DirectoryEntry("LDAP://" + memberColl);
                System.DirectoryServices.PropertyCollection userProps = gpMemberEntry.Properties;
                object obVal = userProps["sAMAccountName"].Value;
                if (null != obVal)
                {
                    groupMemebers.Add(obVal.ToString());
                }
            }
        }
    }
    catch (Exception ex)
    {
        Console.Write(ex.Message);
    }
    return groupMemebers;
}

这应该将该过滤器应用于您的搜索,例如您现在应该只返回该特定城市的用户。
