This book introduces the user to opensource tools for managing Linux clients via Group Policy.

I just though I’d share

Edit: I’m not sure if this actually works. All else fails fall back to Ansible

    Microsoft pulled those from the UI, but if you’re adventurous you can just shove those attributes in to user with power shell and it works the same.

    Then just use sssd instead of NIS, surprised me at work when this worked.

      Do you have any documentation on this by any chance? I don’t really like messing with ad schemas

        sorry I don’t have any real documentation but I have a snippet of powershell that explains it pretty well here this comes from a user creation script I wrote back when they removed the unix UI.

        I was using Get-AdUser and discovered that the properties still existed but you have to manually shove those in, when an sssd “domain bound” linux machine has a user with these props login, they get the defined UID and GID and homefolder etc.

        $otherAttributes = @{}
Write-Host -ForegroundColor Yellow "Adding Linux Attributes"

# get the next numeric uid number from AD
$uidNumber=((get-aduser -Filter * -Properties * | where-object {$_.uidNumber} | select uidNumber | sort uidNumber | select -Last 1).uidNumber)+1

$otherAttributes.Add("unixHomeDirectory","/homefolder/path/$($samAccountName)")
$otherAttributes.Add("uid","$($samAccountName)")
$otherAttributes.Add("gidNumber","$($gidNumber)")
$otherAttributes.Add("uidNumber","$($uidNumber)")
$otherAttributes.Add("loginShell","$($loginShell)")

$UserArgs = @{
    Credential = $creds
    Enabled = $true
    ChangePasswordAtLogon = $true
    Path = $usersOU
    HomeDirectory = "$homeDirPath\$samAccountName"
    HomeDrive = $homeDriveLetter
    GivenName = $firstName
    Surname = $lastName
    DisplayName = $displayName
    SamAccountName = $samAccountName
    Name = $displayName
    AccountPassword = $securePW
    UserPrincipalName = "$($aliasName)@DOMAIN.COM"
    OtherAttributes = $otherAttributes
}

$newUser = New-ADUser @UserArgs

        basically the “OtherAttributes” on the ADUser object is a hashtable that holds all the special additional LDAP attributes, so in this example we use $otherAttributes to add all the fields we need, you can do the same with “Set-Aduser” if you just wanna edit an existing user and add these props

        the @thing on New-ADuser is called a splat, very useful if you’re not familiar, it turns a hashtable into arguments

        lemme know if you have any questions

          I think you could boil it down to something like Set-ADUser bob -otherattributes {uidNumber=1005, gidNumber=1005}
