view log problem with path authorization

Newbie question - I have authenticated users with read or r/w access are unable to view logs, eg:

    # svn --username whatever --password xxxxx svn://svn/repos/project/yada.txt

    svn: Item is not readable

I must grant anonymous read access in authz and then it works:

    [/]

        * = r

I've seen this reported earlier but no answer:

My question is why can't an authenticated user who has rights see the logs?
