Getting a parent's parent for a folder using power shell

Hi,   I am using a powershell script to enable inheritance for the folders created in NTFS share.  In this script, i am getting the folder created for the user by passing a dynamic value and then ...

    the script seems to be working,

    I try it on my side and the result was correct, good job.

    $Permission.SetAccessRuleProtection($False,$true)
Set-Acl -Path $allFolders.FullName -AclObject $Permission

    In the first line and as the $Permission is holding the folder ACL information, there is one of the methods called SetAccessRuleProtection, you can find all other methods and properties by using $Permission | Get-Member.

    More info here

    The SetAccessRuleProtection accepts 2 input IsProtected and PreservedInheritance 

    SetAccessRuleProtection (bool isProtected, bool preserveInheritance);

    IsProtected: Type is Bool ($True/$false) , $False= Enable Inheritance

    PreservedInheritance : This parameter is actually ignored as the IsProtected is set to false

     

    Thanks

Thanksfarismalaeb .

 

I tested the script few more times and yes it is not inheriting the permissions from parents parent.

 

So, will the below logic work ?

If the parent length is one, set the permission on parent to inherit from it's parent and then set the homefolder to inherit from it's parent.

 

Example :

HomeFolder : C:\OIMShare2\b\test\

Here the 'test' parent would be 'b'. so, inherit the permission from OIMShare2 to 'b' and after that set the permissions on 'test' to inherit from 'b'.

 

$the_shares = 'C:\OIMShare2\b\test\'
$allFolders=Get-ItemProperty -Path $the_shares
if (($allFolders.Parent.Name).Length -eq 1){
Write-Host "My Length is Only 1" 
Write-Host "Setting the permissions of" $allfolders.Name "based on" $allfolders.Parent.Parent.Name
$Permission=get-acl -Path $allfolders.Parent.Parent.FullName
$Permission.SetAccessRuleProtection($False,$true)
Set-Acl -Path $allfolders.FullName -AclObject $Permission
}
Else{
Write-Host "The Parent Length is longer than 1"
Write-Host "Setting the permissions of" $allfolders.Name "based on" $allfolders.Parent.Name
$allFolders.Parent.Name
$Permission=get-acl -Path $allfolders.Parent.FullName
$Permission.SetAccessRuleProtection($False,$true)
Set-Acl -Path $allfolders.FullName -AclObject $Permission
}

 

Thanks in advance

Yes surely the logic is possible and doable via powershell
Let me ask u on more question
This is Grandfather, Father, son relation
This should go in order
Maybe ibam asking the question again, but i am a bit confused.
Do u want to enable inherent in all the chain or u want to copy the permission?!

    I would like enable inheritance so that it would get all the permissions.

    But, What is the difference between enable inherent in all the chain or u copying the permission?

    Thank you,
