Can't remove restrictions from pdf file

Hello,

I’m using this article How to Remove All Restrictions from PDF in C# to remove all restrictions but it’s not doing nothing.

The actual code I’m using is :

public void MssRemoveSecuritySettings(byte[] ssLicense, byte[] ssFile, string ssPassword, out bool ssResult, out string ssResultMessage, out byte[] ssOutFile) {

    ssOutFile = new byte[] { };
    ssResult = false;
    ssResultMessage = "";

    try
    {
        setPdfLicense(ssLicense);
        MemoryStream inStream = new MemoryStream(ssFile);

        // Create PdfFileSecurity object
        PdfFileSecurity fileSecurity = new PdfFileSecurity();
        fileSecurity.BindPdf(inStream);

        // empty password?
        if (!string.IsNullOrEmpty(ssPassword))
        {
            // decrypt if we have password
            fileSecurity.DecryptFile(ssPassword);
        }

        // Create DocumentPrivileges object
        var privilege = DocumentPrivilege.AllowAll;

        // Set Privilege
        fileSecurity.SetPrivilege(privilege);    

        MemoryStream OutStream = new MemoryStream();
        fileSecurity.Save(OutStream);

        ssOutFile = OutStream.ToArray();
        ssResult = true;
        ssResultMessage = "Success";
    }
    catch (Exception e)
    {
        ssResult = false;
        ssResultMessage = e.Message;
    }
}

The output file has the same restrictions as the input file.

Our example file has :
Security Method : Password Security
Document Assembly : Not Allowed
age Extraction : Not Allowed

And we wanted to allow both.
