ldapjs api not authenticating from form. It works if passwrod hardcoded

Folks, I would appreciate if you could help me with below. Now if hardcode username and password in the code, I can log in. But with form submit it is always invalid credential error.

{ InvalidCredentialsError: 80090308: LdapErr: DSID-0C0903D9, comment:    AcceptSecurityContext error, data 52e, v2580

`

var url="ldap://ldap.company.com:389";
var dn='DC=Company,DC=com';
var bindUser="user@mycompany.com";
var bindPass='ldappassword';
var password="mypassword";
var ldapres = null

var opts = {
  scope: 'sub',
}
var client = ad.createClient({ "url":url , "bindDN":     bindUser, "bindCredentials": bindPass });


app.post('/api/ldap/authenticate', function (req, res) {
ldapres=null;
var name=req.body.username;
password=req.body.password;

console.log('username: -'+name+'- pass: -'+password+"-");
opts.filter= "(&(objectClass=user)(sAMAccountName=" +name + "))",
client.search(dn, opts, function (err, result) {
console.log('inside search'); 
 result.on('searchEntry', function (entry) {
    ldapres = entry.raw
console.log(ldapres.dn);
  })

 result.on('end', function (result) {
  if (!ldapres) { 
console.log('Invalid username');
return res.send('Invalid username') 
}

client.bind(ldapres.dn, password, function (err) {
  if (err) { 
  console.log(err);
  return res.send('Wrong password') 
   client.unbind();
  }
else{
console.log('You are loggedin');
    res.send('You are logged')
}
  })

 })
}) 

}); `

Appreciate your help.
