I confirm the issue and raise priority

I also confirm the same issue in 2.5.28.

Login page only shows for a Read More

Isnt this the expected behaviour.

There were many discussions on this in the past and Elin was always
insistent that this was the correct thing to do. (Not saying that I agree)

Not sure how to change this behavior, but I disagree with it being the correct thing to do.
IMHO, a 404 should only be displayed when the item does not exist, not when one has no access.
We should be consistent with the Read More functionnality.

I agree it is the wrong behaviour

See Joomlacode for multiple reports of this and discussions

What is the setting Show Unauthorized for com_content?
See https://docs.joomla.org/Restricting_access_to_%22read_more%22

It is off - set to "No"

Here "Show Unauthorized" is set to "On". This setting has NO effect on this issue.

Do you have a readmore. According to the docs if you have show unauthorised
links AND a readmore then the page will display the content before the
readmore and you are then required to login to see the rest.

No read-more’s – the menu link is to a category list with registered permissions on the categories. Get a 404 as if the categories are not there. When logged in, the link works as expected.

@brianteeman
The Read More is not concerned here. We are speaking about displaying a Category (blog or list). As the Category is set to "Registered", we get a 404 instead of a login.

Any update on this issue? we ran into the same issue due to parent category permission which did not allow the group (public), so if we access a direct sub-menu without login, it would give us 404. Instead redirecting to login page would help.

I was able to reproduce the issue with Joomla 3.6.0-dev with default test data:
1. Category "Park Blog" access level set to registered
2. Articles in "Park Blog" set to public
3. Menu item of type Category Blog with access level public:

On front-end: > All Front End Views > clicking on "Article Category Blog" will result in a 404 error.

Not sure how to solve this. The 404 is triggered in libraries/legacy/view/category.php because $category is empty:
public function commonCategoryDisplay()
{
if ($category == false)
{
return JError::raiseError(404, JText::_('JGLOBAL_CATEGORY_NOT_FOUND'));
}

That library is called from components/com_content/views/category/view.html.php
public function display($tpl = null)
{
parent::commonCategoryDisplay();

i think the category false comes from https://github.com/joomla/joomla-cms/blob/staging/components/com_content/models/category.php#L337

Closing this here because we have a PR #11624
