Delete Security role with Powershell from a Document Library

Question

Hi All,

I'm strungling with the following, which I though would be a simple enough task.

I have a couple of hundred sites, on which I have a document library (inheritance broken) and I need to remove a group from each of this document libraries. This is on SharePoint Online, so I need to use the CSOM.

After some stungles I came up with this:

$Username = "UserName"
$Site = "https://testurl/sites/TEST"
$Password = Read-Host -Prompt "Please enter your password" -AsSecureString


#Add references to SharePoint client assemblies and authenticate to Office 365 site
Add-Type -Path "C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\16\ISAPI\Microsoft.SharePoint.Client.dll"
Add-Type -Path "C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\16\ISAPI\Microsoft.SharePoint.Client.Runtime.dll"

$Context = New-Object Microsoft.SharePoint.Client.ClientContext($Site)
$Creds = New-Object Microsoft.SharePoint.Client.SharePointOnlineCredentials($Username,$Password)
$Context.Credentials = $Creds

$Web = $Context.Web
$Context.Load($web)

$curlist=$context.Web.Lists.GetByTitle("Documenten")

$Context.Load($curlist.RoleAssignments)

$Context.ExecuteQuery()

foreach ($ra in $curlist.RoleAssignments)
{
    
    $p=$ra.member
    $Context.Load($p)
    $Context.ExecuteQuery()

    write-host $p.LoginName -ForegroundColor Cyan
    if ($p.LoginName -eq "Projects")
    {
        Write-Host "--> "$p.loginname  -ForegroundColor Green
        $ra.DeleteObject()
        $ra.Update()
       
        
    }

}

I does not generate any errors, and lists the security roles.. But I'm unable to delete the role 'Projects'... 

Anybody a idea in which direction I need to search?

thks

Bart

Hi Rajendra,

Thanks for you reply. This will reset all items in a Document library. I just want to remove a unique role at the Document library level. Is this not possible?

So I have a Document Libary with unique permisions and 4 groups. All I need to do for example is remove "Group 3" and leave everything else intact. 

Is your example adaptable for this?
