如何使用 Powershell 查询 msSFU30MaxUidNumber 属性？

Question

有谁知道查询此 UNIX 属性 msSFU30MaxUidNumber 的方法 使用 Powershell 在 Active Directory 中？我正在编写一个脚本，该脚本将根据需要为用户分配 Unix 属性。我还有 Quest AD Powershell 模块可用。

我借用它来设置 UNIX 属性（NISdomain、GID、loginshell、UIDnumber、UID） http://danieltromp.com/2014/06/09/powershell-ad-enable-unix-attributes/。

我更新了它，因此它也更新了存储的 msSFU30MaxUidNumber。我见过的所有脚本都忘记了这一点。
如果您将来使用 ADUC 设置 UNIX 属性（或者即使您针对另一个 OU 再次运行该脚本），可以防止出现重复 UID 编号的问题：

Remove-Variable -Name * -Force -ErrorAction SilentlyContinue
Import-Module ActiveDirectory
$NIS = Get-ADObject "CN=DOMAIN,CN=ypservers,CN=ypServ30,CN=RpcServices,CN=System,DC=Domain,DC=com" -Properties:* #Get NIS server information
$maxUid = $NIS.msSFU30MaxUidNumber #Get the last used User ID

$usuarios = Get-ADUser -Filter * -SearchBase "OU=NAME,OU=NAME,OU=NAME,DC=Domain,DC=com" -Properties:* #Get all users
foreach($usr in $usuarios)
{
  if ($usr.mssfu30nisdomain -eq $null){
  Set-ADUser -Identity "$($usr.SamAccountName)" -Replace @{mssfu30nisdomain="Domain"} #Enable NIS
  Set-ADUser -Identity "$($usr.SamAccountName)" -Replace @{gidnumber="10005"} #Set Group ID
  Set-ADUser -Identity "$($usr.SamAccountName)" -Replace @{loginShell="/bin/bash"} #Set Login Shell
  $maxUid++ #Raise the User ID number
  Set-ADUser -Identity "$($usr.SamAccountName)" -Replace @{uidnumber=$maxUid} #Set User ID number
  Set-ADUser -Identity "$($usr.SamAccountName)" -Replace @{uid=$usr.SamAccountName} #Set UID
  Write-Host -Backgroundcolor Green -Foregroundcolor Black $usr.SamAccountName changed #Write Changed Username to console
  }
  else{Write-Host -Backgroundcolor Yellow -Foregroundcolor Black $usr.SamAccountName unchanged} #Write Unchanged Username to console with a yellow background
}
$NIS | Set-ADObject -Replace @{msSFU30MaxUidNumber = $maxuid++}
$NIS | Set-ADObject -Replace @{msSFU30MaxUidNumber = $maxuid++}

您似乎可以找到迄今为止分配的最高值存储在 cn=yourYPDomain,cn=ypservers,cn=ypserv30,cn=RpcServices,cn=system,dc=dom 上的 msSFU30MaxUidNumber 属性中,dc=fr。

这是一个按原样给出的脚本：我现在无法在我的配置中测试它，我只是从 Microsoft 法国咨询文档（第 17 页）。

# Get the Yellow page domain and his attribute msSFU30MaxUidNumber
# dom.fr (dc=dom,dc=fr)is my domain
# myYPDomain is the name of my yellow Page domain
$ypDomain = New-Object System.DirectoryServices.DirectoryEntry ("LDAP://societe.fr:389/cn=myYPDomain,cn=ypservers,cn=ypserv30,cn=RpcServices,cn=system,dc=dom,dc=fr","[email protected]","admin")
#$msSFU30MaxUidNumber = $ypDomain.Properties["msSFU30MaxUidNumber"]
$msSFU30MaxUidNumber = $ypDomain.msSFU30MaxUidNumber

# Find a given user
$dn = New-Object System.DirectoryServices.DirectoryEntry ("LDAP://societe.fr:389/dc=dom,dc=fr","[email protected]","admin")
$dsLookFor = new-object System.DirectoryServices.DirectorySearcher($dn)
$dsLookFor.Filter = "(&(samAccountName=user1)(objectCategory=user))"; 
$dsLookFor.SearchScope = "subtree"; 
$n = $dsLookFor.PropertiesToLoad.Add("cn"); 
$n = $dsLookFor.PropertiesToLoad.Add("distinguishedName");
$Usr = $dsLookFor.findOne()

# Assign new value
$Usr.msSFU30MaxUidNumber = $msSFU30MaxUidNumber + 1
$Usr.SetInfo()

# Save the new Value
$ypDomain.msSFU30MaxUidNumber = $msSFU30MaxUidNumber + 1
$ypDomain.SetInfo()

由于您有可用的 Quest AD cmdlet，因此这里有一些基于 JPBlanc 的答案的快速信息。它假设您正在使用已经拥有相关 AD 属性权限的帐户运行脚本：

# The -IncludedProperties parameter is needed because msSFU30MaxUidNumber is not part of Get-QADObject's default attribute set
$ypDomain = Get-QADObject -Identity "cn=myYPDomain,cn=ypservers,cn=ypserv30,cn=RpcServices,cn=system,dc=dom,dc=fr" -IncludedProperties msSFU30MaxUidNumber

$maxUidNumber = $ypDomain.msSFU30MaxUidNumber

$newMaxUidNumber = $maxUidNumber + 1

# Sets the msSFU30UidNumber attribute for User1

Get-QADUser -samAccountName User1 | Set-QADUser -objectAttributes @{msSFU30UidNumber = $newMaxUidNumber}

# Increments the msSFU30MaxUidNumber for the YP domain.

$ypDomain | Set-QADObject -objectAttributes @{msSFU30MaxUidNumber = $newMaxUidNumber}
