Updated Readme.MD to fix a specific issue

[SelfDevTV]

This readme change is a quickfix for people that might run into this nasty little bug #84

I have no idea why the tests are failing. I just changed some lines in the readme.md nothing else.

Me too, no idea why the build fails, but in my humble opinion the Usage alinea is supposed to be short. I would leave that as it was, e.g. with only url,baseDN,username,password. The next chapter (Constructor), where the attributes attribute is explained with even an example is the good spot to mention that 'dn' cannot be left out.

With this change, I'd go ahead and change the whole block to look like:

var config = {
  url: 'foo',
  user: [
    // comment
    'dn'
  ]
}

The current reduced format become illegible with the inlined comments.

Are you sure your branch it up to date with master?

The tests are not passing due to ldapjs/node-ldapjs#686
