Summary: The CoQueryClientBlanket API

!!!!C# Signature:
	[DllImport("ole32.dll")]
	static extern int CoQueryClientBlanket(out IntPtr pAuthnSvc, out IntPtr pAuthzSvc,
		[MarshalAs(UnmanagedType.LPWStr)] out StringBuilder pServerPrincName, out IntPtr
		pAuthnLevel, out IntPtr pImpLevel, out IntPtr pPrivs, out IntPtr pCapabilities);
!!!!User-Defined Types:
None.

!!!!Notes:
The original version of this errored with a message about memory corruption. 
My modification works without error, if you use the code sample you'll need to plug in your own logging.

!!!!Tips & Tricks:
Please add some!

!!!!Sample Code:
{
	System.IntPtr pAthnSvc = new IntPtr();
	System.IntPtr pAthzSvc = new IntPtr();
	StringBuilder pServerPrincName = new StringBuilder();
	System.IntPtr pAuthnLevel = new IntPtr();
	System.IntPtr pImpLevel = new IntPtr();
	System.IntPtr pPrivs = new IntPtr();
	System.IntPtr pCaps = new IntPtr(4);

try
	{
		trc.Log(LOG_DEBUG, "Retrieving Principle Name");			
		CoQueryClientBlanket(out pAthnSvc, out pAthzSvc, out pServerPrincName, out pAuthnLevel, out pImpLevel, out pPrivs, out pCaps);

trc.Log(LOG_DEBUG, "Called CoQueryClientBlanket without error");
	}
	catch(Exception ex)
	{
		// Something went wrong, report it and then check if 
		//we have a valid token attached instead
		trc.LogError( ex.Message ) ;
	}
	finally
	{
		// Logging the values to aid any debugging that may be required
		trc.Log( LOG_DEBUG, "Values");
		trc.Log( LOG_DEBUG, "pAthnSvc = " + pAthnSvc);
		trc.Log( LOG_DEBUG, "pAthzSvc = " + pAthzSvc);
		trc.Log( LOG_DEBUG, "pAuthnLevel = " + pAuthnLevel);
		trc.Log( LOG_DEBUG, "pImpLevel = " + pImpLevel);
		trc.Log( LOG_DEBUG, "pPrivs = " + pPrivs);
		trc.Log( LOG_DEBUG, "pCaps = " + pCaps);
		trc.Log( LOG_DEBUG, "pServerPrincName = " + pServerPrincName);
	}
}

Do you know one?  Please contribute it!
