archives].

Summary:
Subversion tries (via APR) to resolve the exact case of all paths
passed to it. This fails because this specific example has a path that is 
unreadable in its path.


In this case it tries apr tries to find the casing of these path nodes
c:\documents and settings
c:\documents and settings\MyName
c:\documents and settings\MyName\SomePath
(Where C:\Documents and Settings is a Junction to C:\Users)

And Vista explicitly denies FILE_READ_DATA rights on all items directly below 
the 'C:\Documents and Settings' junction.

You can see this via:
C:\>cacls "c:\Documents and Settings"
C:\Documents and Settings
                          Everyone:(DENY)(special access:) FILE_READ_DATA
                          Everyone:R
                          NT AUTHORITY\SYSTEM:F
                          BUILTIN\Administrators:F

This makes it impossible to ask for the exact casing of
C:\Documents and Settings\MyName

If I create my own junction without this explicit denial I can use subversion 
as usual.

This issue should be fixed in Apr if a workaround can be found. Other 
workarounds are removing the deny on this (hidden) junction or just using the 
real folder (C:\Users\MyName)
