sspi in c#I have been trying to use SSPI in validating user credentials in my winform
applications. I have tried looking around the internet but it doesn't seem that there are any code samples for wrapping sspi in c#. Could someone give me a hand? I have found examples in C++ but i am not familiar with it so I would greatly appreciate if someone would offer help. p.s. I have found examples in VB.net but i am having difficulties in defining the correct datatypes in c#. i have also found a simple solution on work around in sspi using NegotiateStream but that's for framework 2.0 only and i am using framework 1.1 at the moment Why don't you compile the VB.NET version and reverse compile it in
Reflector? That usually works pretty well. The reflector file disassembler plug-in makes it even easier. Joe K.

You should still have vbc.exe on your machine so that
you can compile file the command line. The other thing to do would be to follow Dominick's link instead. Joe K.

yeah, that's life. As what you suggested i eventually managed to get the dll compiled from that VB.Net code and disassemble it back to c#, and it works well. Thank you for advice though.

IIRC you can use the SSPI Remoting classes to do the same handshake for validating a credential. http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dndotnet/html/remsspi.asp --------------------------------------- Dominick Baier - DevelopMentor http://www.leastprivilege.com Show quoteHide quote > I have been trying to use SSPI in validating user credentials in my > winform applications.

I have come across this example, I tried to use the SSPI library provided that but then i found out i cannot use other people's username/password. It enforces me to use my own password and that does not satisfies my purpose of logging in as another user. vincent Show quoteHide quote "Dominick Baier [DevelopMentor]" wrote: > Hello Vincent, > > IIRC you can use the SSPI Remoting classes to do the same handshake for validating > a credential. > > http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dndotnet/html/remsspi.asp > > --------------------------------------- > Dominick Baier - DevelopMentor > http://www.leastprivilege.com > > > I have been trying to use SSPI in validating user credentials in my > > winform applications.
