File Access Control and WebDAV

folder A has no file access control applied, it has an a sub-folder B which has a Collaborate tag prevent it from being accessed by a certain client, then WebDAV PROPFIND call to list content in folder A will be denied from the blocked client. Is this normal?

It looks not right. Another independent folder (outside A’s folder structure) is working correctly?
And it is just this specific client that is refused?

If you can give more details, e.g. version numbers, settings, logfiles, … we can try an reproduce if this is a bug…
