Step 1：Creating a Linked Server.
EXEC sp_addlinkedserver 'ADSI', 'Active Directory Services 2.5', 'ADSDSOObject', 'adsdatasource'
Step 2：Creating a SQL Server Authenticated Login
EXEC sp_addlinkedsrvlogin @rmtsrvname = N'ADSI', @locallogin = NULL , @useself = N'False', @rmtuser = N'domain\Account', @rmtpassword = N'Password'
對于 SQL Server 授權登錄，可以使用sp_addlinkedsrvlogin 系統存儲過程配置用于連接到目錄服務的適當的登錄/密碼.
參考這里: http://blogs.msdn.com/euanga/archive/2007/03/22/faq-how-do-i-query-active-directory-from-sql-server.aspx
如果SQLServer使用Windows 授權登錄，只需自映射就足以通過使用 SQL Server 安全委托來訪問AD。簡單點說就是直接運行第三步語句即可.
Step 3：Querying the Directory Service.
復制代碼 代碼如下:
-- Query for a list of User entries in an OU using the SQL query dialect
select convert(varchar(50), [Name]) as FullName,
convert(varchar(50), Title) as Title,
convert(varchar(50), TelephoneNumber) as PhoneNumber
from openquery(ADSI,
'select Name, Title, TelephoneNumber
from ''LDAP://OU=Directors,OU=Atlanta,OU=Intellinet,DC=vizability,DC=intellinet,DC=com''
where objectClass = ''User''')
-- Query for a list of Group entries in an OU using the SQL query dialect
select convert(varchar(50), [Name]) as GroupName,
convert(varchar(50), [Description]) GroupDescription
from openquery(ADSI,
'select Name, Description
from ''LDAP://OU=VizAbility Groups,DC=vizability,DC=intellinet,DC=com''
where objectClass = ''Group''')

說明：但是這樣默認查詢出來的是1000個對象.怎么辦呢?
方法一,通過字母來循環.見以下:
復制代碼 代碼如下:
CREATE TABLE #tmpADUsers
( employeeId varchar(10) NULL,
SAMAccountName varchar(255) NOT NULL,
email varchar(255) NULL)
GO
/**//* AD is limited to send 1000 records in one batch. In an ADO interface you can define this batch size, not in OPENQUERY.
Because of this limitation, we just loop through the alphabet.
*/
DECLARE @cmdstr varchar(255)
DECLARE @nAsciiValue smallint
DECLARE @sChar char(1)
SELECT @nAsciiValue = 65
WHILE @nAsciiValue 91
BEGIN
SELECT @sChar= CHAR(@nAsciiValue)
EXEC master..xp_sprintf @cmdstr OUTPUT, 'SELECT employeeId, SAMAccountName, Mail FROM OPENQUERY( ADSI, ''SELECT Mail, SAMAccountName, employeeID FROM ''''LDAP://dc=central,dc=mydomain,dc=int''''WHERE objectCategory = ''''Person'''' AND SAMAccountName = ''''%s*'''''' )', @sChar
INSERT #tmpADUsers
EXEC( @cmdstr )
SELECT @nAsciiValue = @nAsciiValue + 1
END
DROP TABLE #tmpADUsers
