Meta-robots Nofollow on logins and admins

[Endora]

In my SEO MOZ reports I am getting over 400 errors as Meta-robots Nofollow. These are all leading to my admin login page which I do not want robots in. Should I put some code on these pages so the robots know this and don't attempt to and I do not get these errors in my reports?

Yes you can noindex that page to prevent robots from entering. Go to your robot.txt file and add "disallow with your URL. http://www.robotstxt.org/robotstxt.html

I think that's probably fine - we're warning you just to tell you the pages are blocked, but blocking them sounds perfectly sensible. Is Google indexing them at all?

I assume that the login page is getting multiple URLs, possibly based on the path people take to it? Ideally, it would help to collapse that to one URL (store the parameters in a form field or visitor session/cookie), but my gut reaction is that that's a nice to have. I suspect you're probably ok.
