[Mono-osx] How to logon to Win or Mac using credentials through code?

[d_v]

Does anyone have a good way to logon to Windows and a Mac using credentials
through code?

I am using the Impersonator code and am now trying to get it to run on Mac
2.2_5 (latest build).

The error I recieved was:

System.DllNotFoundException: advapi32.dll
  at (wrapper managed-to-native) MiscImpersonate.Impersonator:RevertToSelf
()
  at MiscImpersonate.Impersonator.ImpersonateValidUser (System.String
userName, System.String domain, System.String password) [0x00000] 
  at MiscImpersonate.Impersonator..ctor (System.String userName,
System.String domainName, System.String password) [0x00000] 
  at My_App.Form1.VerifyClientSettings_FileFilter () [0x00000]


The Impersonator code is from:

Here is the Impersonator code in my MiscImpersonate unit in C# for DotNet
2.x:
