Question

这是我今早早些时候提出的一个问题的后续跟踪（posted here。）按照提供的说明，我设法在SQL Server 2000数据库中查询与AD组关联的SID。然而，SID看起来像这样：

0x0123456789ABCDEF0123456789ABCDEF0123456789ABCDEF01234567

如何获取SID引用的AD组的名称？我尝试使用Google搜索PowerShell脚本，但是，他们的大多数SID示例都是这样的：

S-1-5-21-1454471165-1004335555-1606985555-5555

显然，这看起来不像我从SQL Server返回的值。我怎么能这样做？

Answer 1

如果您正在使用sqlps（SQL Powershell主机），它可以对抗SQL 2000（我已在2000实例上对此进行了测试），您可以使用：

$query = @"
select sid from syslogins where isntgroup = 1
AND name = 'CONTOSO\mylogin'
"@

invoke-sqlcmd -ServerInstance "myserver" -Database master -Query $query | 
foreach {$SID = new-object security.principal.securityidentifier($_.SID,0); $SID.translate([system.security.principal.NTAccount]) }

Answer 2

对于那些没有sqlps的人：使用这个在线C＃shell做单格式sid到文本
