The USER_FUNC handler receives rather detailed information:

array(
   'currentUrl' => [requested uri],
   'reasonText' => [textual explanation],
   'pageAccessFailureReasons' => [array with access information for the 
rootline]
)

The pageAccessFailureReasons array contains the properties which lead to 
the denied access:
array(
   'hidden' => array( [pageId] => TRUE, ... ),
   'starttime' => array( [pageId] => [starttime], ... ),
   'endtime' => array( [pageId] => [endtime], ... ),
   'fe_group' => array( [pageId] => [fe_group], ... )
)

If 'extendToSubpages' was set for a page higher in the rootline the page 
ID of that page is used in the array.

The reasonText can be found in 
\TYPO3\CMS\Frontend\Controller\TypoScriptFrontendController (previously 
tslib_fe ); search for page(.*)AndExit .

About 401: "The response MUST include a WWW-Authenticate header field 
containing a challenge applicable to the requested resource."
The normal login in a TYPO3 site is not done by HTTP Authentication.

It would be nice to have more powerful 404 handling. Maybe it can be 
done with an extension. If this extension needs something from the core 
it can always be introduced.
