I've a requirement to authenticate the users against windows NT Domain Accounts.I've initialized the LoginContext with NTLoginModule and the CallbackHandler(that holds the user that has to be authenticated). I inferred that, NTLoginModule does not authenticate the user that is present in the callbackhandler rather it authenticates the current user that has logged in into the NTSystem.Any information related with how to retrive the NT Domain Accounts would be of hlp, also where NT Login Module is used.
