SVN CLI and Windows security

I ran into a situation today concerning the command line client and windows security. The problem is that the user (a build user performing automated builds on a Windows 2003 VM) attempted to check out a file to a network share and couldn't, apparently because that user doesn't have access to the share root, even though it does have access to the directory into which the file should be exported.

The command I used was:

svn export http://server/trunk/dir1/dir2/file.txt \\server\share\dir1\dir2\dir3\file.txt --non-interactive --force

To which svn.exe responded:

svn: Error resolving case of '\\server\share\dir1\dir2\dir3\file.txt'

In that tree, the user has no rights to \\server\share\, but has read/write access to dir1 and below. If, as that user, I do 'dir \\server\share', I see nothing, but if I do 'dir \\server\share\dir1', I see everything just fine.

Now, in our case, that shouldn't be a problem much longer because the network guys are in the process of changing the access rights on that directory; the build user really should have access there. However, I don't think it's unreasonable to assume that there might be a legitimate reason for such a restriction.

Is there something we did wrong here (aside from the rights issue) that would have allowed the export to happen despite the access rights? FWIW, 'svn checkout' resulted in the same type of error.

When the network guy saw it, he said, "Maybe they're using the old NT4 method of stepping through the tree, rather than going straight to the location specified." Is there something in whatever layer svn is using for this that accesses the tree step by step rather than as one entity? And is it worth "fixing" if it is a problem?
