NT CWS - Container - SecurityDescriptor

Question

Hello,
In the code (Container.cs) that implements the IContainer interface, there is a function called GetGroups() which gets the NT User groups associated with the directory. Within this function, there is a call to a function GetACLEntries which returns the users associated with the file location.
I am trying to use the SecurityDescriptor to call GetFileSecurity() - like this: SecurityDescriptor secDesc = SecurityDescriptor.GetFileSecurity(fileLoc);
However, it does not seem to be recognized. I have imported and referenced mmsseclib.dll in order to use "Microsoft.Win32.Security" which should contain the SecurityDescriptor class but doesn't. This excercise was done in one of the labs in "BEA ALUI IDK 6.0 Part 2 - Develop Web Services" course. Below is the function with all the using statements. C#, Visual Studio 2003 . Please help.
using System;
using System.Collections;
using System.Text;
using com.plumtree.openfoundation.util;
using log4net;
using Microsoft.Win32;
using Microsoft.Win32.Security;
using Plumtree.Remote.Crawler;
using Plumtree.Remote.Util;
public static ACLEntry[] GetACLEntries(string fileLoc, bool groups)
Log("[FUNCN] public static ACLEntry[] GetACLEntries(String fileLoc, bool groups)");
Log("fileLoc:" + fileLoc);
Log("groups:" + groups);
ArrayList al = new ArrayList();
SecurityDescriptor secDesc = SecurityDescriptor.GetFileSecurity(fileLoc);
using (secDesc)
     foreach (Ace ace in secDesc.Dacl)
          try
               //if it's a group and it has access, add it.
               if (ace.Sid.IsValid)
                    if (groups)
                         if ((ace.Sid.GetNameUse().Equals(SID_NAME_USE.SidTypeGroup) || ace.Sid.GetNameUse().Equals(SID_NAME_USE.SidTypeWellKnownGroup)) && ace.Type.Equals(AceType.ACCESS_ALLOWED_ACE_TYPE))
                              if (ace.Sid.AccountName.ToUpper().Equals(EVERYONE_GROUP_NAME))
                                   Log("[EVERYONE GROUP ADDED] " + fileLoc + " - group:" + groups.ToString() + " - domain:" + ace.Sid.DomainName + ";account:" + ace.Sid.AccountName + ", NameUse:" + ace.Sid.GetNameUse().ToString());
                              //return new ACLEntry[]{new ACLEntry(secDesc.Group.DomainName, EVERYONE_GROUP_NAME)};
                              al.Add(new ACLEntry(secDesc.Group.DomainName, EVERYONE_GROUP_NAME));
                              else
                              Log("[GROUP ADDED] " + fileLoc + " - group:" + groups.ToString() + " - domain:" + ace.Sid.DomainName + ";account:" + ace.Sid.AccountName + ", NameUse:" + ace.Sid.GetNameUse().ToString());
                                   al.Add(new ACLEntry(ace.Sid.DomainName, ace.Sid.AccountName));
                         else
                              Log("[GROUP NOT ADDED] " + fileLoc + " - group:" + groups.ToString() + " - domain:" + secDesc.Group.DomainName + ";account:" + ace.Sid.AccountName + ", NameUse:" + ace.Sid.GetNameUse().ToString());
                    else
                    if (ace.Sid.GetNameUse().Equals(SID_NAME_USE.SidTypeUser) && ace.Type.Equals(AceType.ACCESS_ALLOWED_ACE_TYPE))
                         Log("[USER ADDED] " + fileLoc + " - group:" + groups.ToString() + " - domain:" + ace.Sid.DomainName +
                                             ";account:" + ace.Sid.AccountName + ", NameUse:" + ace.Sid.GetNameUse().ToString());
                         al.Add(new ACLEntry(ace.Sid.DomainName, ace.Sid.AccountName));
                    else
                         Log("[USER NOT ADDED] " + fileLoc + " - group:" + groups.ToString() + " - domain:" + ace.Sid.DomainName + ";account:" + ace.Sid.AccountName + ", NameUse:" + ace.Sid.GetNameUse().ToString());
          else
               Log("[NOT VALID] " + fileLoc + " - " + ace.Sid.AccountName);
catch (Exception ex)
     logger.Error("[****ERROR ENCOUNTERED****] GetAclEntries(" + fileLoc + "," + groups + ")", ex);
return (ACLEntry[]) al.ToArray(typeof (ACLEntry));
}

Okay, so I ended up downloading a project that used win32security.dll and used that DLL which got the function/class to compile.
Now in the CWSUtilities class, there are EncryptString and DecryptString functions that require use of the PTCipherUtilityClass found in com.plumtree.utility. Again, I can not find this DLL/library so that I can compile. I found an old community forum posting of someone having the same issue. So I'd like to re-open this issue and see if anyone out there has a solution. Here is the old posting:
http://209.85.173.132/search?q=cache:m4GJbr7ezPoJ:forums.bea.com/message.jspa%3FmessageID%3D500017506%26+NTCWS&hl=en&ct=clnk&cd=3&gl=ca
Here is the EntryptString function:
public static string EncryptString(string val, string key)
     Log("[FUNCN] public static string EncryptString(string val, string key)");
     PTCipherUtilityClass cipher = new PTCipherUtilityClass();
     string output = cipher.Encrypt(val, key);
     return output;
Where and How can I use com.plumtree.utility so that I can access PTCipherUtilityClass?
