tsql - 通过SQL递归查询AD组成员身份

Question

背景

我正在创建一些 SQL 来协助安全审计；这将从各种系统数据库和 Active Directory 获取安全信息，并将生成所有异常的列表(即帐户在一个系统中关闭而不是其他系统中的情况。

当前代码

要获取属于安全组成员的用户列表，我运行以下 SQL:

if not exists(select 1 from sys.servers where name = 'ADSI') 
    EXEC sp_addlinkedserver 'ADSI', 'Active Directory Services 2.5', 'ADSDSOObject', 'adsdatasource'

SELECT sAMAccountName, displayName, givenName, sn, isDeleted --, lastLogonTimestamp --, lastLogon (Could not convert the data value due to reasons other than sign mismatch or overflow.)
FROM OPENQUERY(ADSI
, 'SELECT sAMAccountName, displayName, givenName, sn, isDeleted
FROM ''LDAP://DC=myDomain,DC=myCompany,DC=com''
WHERE objectCategory = ''Person''
AND objectClass = ''user'' 
AND memberOf = ''CN=mySecurityGroup,OU=Security Groups,OU=UK,DC=myDomain,DC=myCompany,DC=com''
')
order by sAMAccountName

问题/疑问

我希望这段代码能够递归地工作；即，如果用户是指定组成员的组的成员，则也应包括他们(对于完整层次结构)。有谁知道如何通过 SQL 做到这一点？

更新

我现在已经解决了一些问题(与引用的问题无关，而是我遇到的其他一些问题)。

lastLogon 抛出错误。这是因为服务器版本是 x86。使用 x64 数据库解决了这个问题。

lastLogon 以数字形式返回。添加了一些代码以将其转换为 DateTime2。

通过使 OpenQuery 本身动态化，我能够将组名从硬编码字符串中移出，因此在 OpenQuery 的上下文中，生成的字符串看起来是静态的。

--create linked server
if not exists(select 1 from sys.servers where name = 'ADSI')
begin
    --EXEC sp_addlinkedserver 'ADSI', 'Active Directory Services 2.5', 'ADSDSOObject', 'adsdatasource'
    EXEC master.dbo.sp_addlinkedserver 'ADSI', 'Active Directory Service Interfaces', 'ADSDSOObject', 'adsdatasource'
    EXEC master.dbo.sp_serveroption @server=N'ADSI', @optname=N'collation compatible',  @optvalue=N'false'
    EXEC master.dbo.sp_serveroption @server=N'ADSI', @optname=N'data access', @optvalue=N'true'
    EXEC master.dbo.sp_serveroption @server=N'ADSI', @optname=N'dist', @optvalue=N'false'
    EXEC master.dbo.sp_serveroption @server=N'ADSI', @optname=N'pub', @optvalue=N'false'

    EXEC master.dbo.sp_serveroption @server=N'ADSI', @optname=N'sub', @optvalue=N'false'
    EXEC master.dbo.sp_serveroption @server=N'ADSI', @optname=N'connect timeout', @optvalue=N'0'
    EXEC master.dbo.sp_serveroption @server=N'ADSI', @optname=N'collation name', @optvalue=null
    EXEC master.dbo.sp_serveroption @server=N'ADSI', @optname=N'lazy schema validation',  @optvalue=N'false'
    EXEC master.dbo.sp_serveroption @server=N'ADSI', @optname=N'query timeout', @optvalue=N'0'
    EXEC master.dbo.sp_serveroption @server=N'ADSI', @optname=N'use remote collation',  @optvalue=N'true'
    EXEC master.dbo.sp_serveroption @server=N'ADSI', @optname=N'remote proc transaction promotion', @optvalue=N'true'
end


declare @path nvarchar(1024) = 'DC=myDomain,DC=myCompany,DC=com'
declare @groupCN nvarchar(1024) = 'CN=My Security Group,OU=Security Groups,OU=UK,' + @path
, @sql nvarchar(max)

--construct the query we send to AD
set @sql = '
SELECT sAMAccountName, displayName, givenName, sn, isDeleted, lastLogon
FROM ''LDAP://' + replace(@path,'''','''''') + '''
WHERE objectCategory = ''Person''
AND objectClass = ''user'' 
AND memberOf = ''' + replace(@groupCN,'''','''''') + '''
'

--now wrap that query in the outer query
set @sql = 'SELECT sAMAccountName, displayName, givenName, sn, isDeleted
, case     
    when cast([lastLogon] as bigint) = 0 then null
    else dateadd(mi,(cast([lastlogon] as bigint) / 600000000), cast(''1601-01-01'' as datetime2)) 
  end LastLogon
FROM OPENQUERY(ADSI, ''' + replace(@sql,'''','''''') + ''')
order by sAMAccountName'

--now run it
exec(@sql)

尽管这是一篇旧帖子，但 Google 仍然喜欢将其放在结果的顶部，因此当我在同一问题上苦苦挣扎时，我想发布我的发现/解决方案，感谢 Riverway 让我参与正确的轨道上。

创建存储过程:

CREATE PROCEDURE [dbo].[GetLdapUserGroups]
    (
    @LdapUsername NVARCHAR(max)
    )
AS
BEGIN
DECLARE @Query NVARCHAR(max), @Path NVARCHAR(max)

SET @Query = '
    SELECT @Path = distinguishedName
    FROM OPENQUERY(ADSI, ''
        SELECT distinguishedName 
        FROM ''''LDAP://DC=DOMAIN,DC=COM''''
        WHERE 
            objectClass = ''''user'''' AND
            sAMAccountName = ''''' + @LdapUsername + '''''
    '')
'

EXEC SP_EXECUTESQL @Query, N'@Path NVARCHAR(max) OUTPUT', @Path = @Path OUTPUT 

  SET @Query = '
    SELECT cn AS [LdapGroup]
    FROM OPENQUERY (ADSI, ''<LDAP://DOMAIN.COM>;
    (&(objectClass=group)(member:1.2.840.113556.1.4.1941:= ' + @Path + '));
    cn, adspath;subtree'')
    ORDER BY cn;
'

EXEC SP_EXECUTESQL @Query
END

然后，只需传递用户名即可调用您的 SP:

DECLARE @UserGroup table (LdapGroup nvarchar(max))
INSERT INTO @UserGroup exec Datamart.dbo.GetLdapUserGroups @LdapUser

然后我使用哈希表将 AD 组与 SQL 数据以及最终用户应该看到的内容正确匹配。

DECLARE @RptPermissions table (ldapGroup nvarchar(max),scholarshipCode nvarchar(50),gender nvarchar(2))
INSERT INTO @RptPermissions VALUES('EMP_Enrollment_Admissions','ALL','MF')

就我而言，我使用它来拉取 SSRS 用户变量并将其传递到查询中以根据 AD 组成员身份选择记录。

;WITH CTE_Permissions AS
(
    SELECT
        p.scholarshipCode
        ,p.gender
    FROM @UserGroup AS g
    JOIN @RptPermissions AS p ON
        g.ldapGroup = p.ldapGroup
)

...稍后在查询中

JOIN CTE_Permissions AS p ON
         s.SCHOLARSHIP_ID = p.scholarshipCode
         OR p.scholarshipCode = 'ALL'

希望这可以帮助。
