[TYPO3-english] Error requested page didn't have a proper connection to the tree-root

[Xavier Perseguers]

Hi,

Part of my website is protected and only shown once logged-in. This part is mounted. When I try to access a page that is protected I get this error:

-----------
Error!

The requested page didn't have a proper connection to the tree-root!

(MP value remain!)
-----------

Question 1: who knows how to redirect to some page instead of showing this message? (the login page in my case)

Question 2: is there some built-in mechanism to show the login form when trying to access a protected page and then automatically redirect to it once logged in? If so and if there is nothing special 
to do, why isn't it working with mount point? known issue?
