Alternative Managed API:
Do you know one? Please contribute it!
Tips & Tricks:
To determine required buffer size, call first with pPackedCredentials = IntPtr.Zero. Should return error code 160, but pcbPackedCredentials will be populated with the expected buffer size. Use Marshal.AllocCoTaskMem() to allocate the appropriate buffer, then call again, this time passing the allocated buffer.
The CredPackAuthenticationBuffer function converts a string user name and password into an authentication buffer.

An IntPtr is a pointer to a memory location (unmanaged) that adapts to the platform it is running on (64-bit, etc.) UNLIKE a standard int/Integer. You should always use this type for unmanaged calls that require it, even though an int will appear to work on your development machine.
