[support] Showing login block on access denied

[Shérab]

Dear Don,

Thank you so much for your so useful response!
One other thing I'm looking for is a way to have different access denied
pages depending on the ressource the user attemps to access. To be more
precise, the site is a digital library. When a user wants to download a
book then what should happen is what has been described in the previous
message. But for any other page the user tries to see while not being
allowed to do so, he/she should get Drupal's default access denied page.
Is that doable ?

Thank you !
Sherab.
