windowsStrategy = new windowsStrategy({
ldap: {
url: 'serverName', //
base: 'DC',
bindDN: 'username',//req.body['username'],
bindCredentials: 'password'//req.body['password']
},passReqToCallback:true,
integrated: false

}, function(req,profile, done){
console.log(profile);
})

app.post('/log',
function (req, res){
//console.log(req.body['username']);
passport.use(windowsStrategy);
windowsStrategy.authenticate(req)
});
