I was a bit surprised by this behaviour, so I stepped through the code to
check what exactly happens ( code on svn trunk, but I think behaviour is the
same as svn 1.3 ). I checked read behaviour by doing an update of the trunk
folder of my test repository.
Authentication works in three steps:
1. Repository wide check, will allow anonymous access if possible, otherwise
request credentials. This check is based purely on the anon-access property.
2. Opens the root folder of your request ( not the root of the repository!
). If anon-access=read but path-based authz fails, no credentials are asked!
3. CD's recursively in the subfolders. If anonymous access fails for one of
these folders, request credentials. That user will be used for all other
Step 2 is the check which fails with an 'Not authorized to open root of edit
operation' error. I'm not sure why it isn't asking for credentials here. I
suppose it should, because the current result is that an action on a working
copy fails or succeeds depending on which folder you start the action.
I try to get some more information whether or not this is expected behaviour
( but I'm already working on another authz issue, so this might take some
I think this is not only Windows specific either, just a consequence of the
new path-based authz mechanism in svn 1.3 .

The bug I was talking about is issue 2486, it only shows up in the commit
