How to assign the user login block to header region I created a user and I logged in as the user by visiting xxx.com/user. I just visited xxx.com/user. I see the user name but I do not see any log out button. I am not sure how I logout. 

Thanks.

The Drupal core User login block doesn't display a login/logout link; it only displays a form for logging in an anonymous user. If you want a block to display logout, the User Menu block displays user-specific menu links that also includes a logout link when a user is logged in.
