How to add a user/login Link to the Maintenance Mode page? I have my site in Maintenance Mode. I know I can get to my login page by going to http://example.com/login .

My client wants a login link on the Maintenance Mode page (when in this mode). Before I say "no this is not possible", I am wondering if this is possible. I could add this to the Maintenance template page right? I already have a custom Maintenance Mode page.

EDIT: Where the http://adaptivethemes.com/how-to-theme-the-user-login-page-in-maintenance-mode
solution works, its not what I want. All I want is a link to the user login page displayed on the Maintenance Page.

I did try this: I added html to the maintenance php template:  &lt;div&gt;&lt;a href="/user/login" &gt;Login&lt;/a&gt;&lt;/div&gt; 

HOWEVER this only show a link that was NOT clickable. Also how would I get to the User login page if I am testing this on a test server, but the domain will be different than on the test server. Change the domain once on the production server?
Yes, you should be able to. You can create a maintenance page template similar to any other in Drupal, "maintenance-page.tpl.php". However, to get that to work you probably have to make some changes to your template.php file. 

More info can be found here: http://adaptivethemes.com/how-to-theme-the-user-login-page-in-maintenance-mode although I believe that example is from Drupal 6, but the idea should be fairly similar for Drupal 7 as well.
