[rdiff-backup-users] Security Violation

[Jeff Burns]

I have rdiff-backup 1.1.5 installed under cygwin on two computers. The
server, named red, runs Windows 2000; and the client, named black, runs XP.
I can make backups from black to red, but other operations from black to red
fail with a Security Violation. I first discovered this with
--remove-older-than, but found that other commands have the same behavior.
The simplest example is --list-increments.

If I log directly into red all the commands work. I am using the
administrator account on both systems, but on red the administrator account
is renamed. 

This appears to be a bug. Is there a patch? Also, has anyone got access
control list and extended attributes working with NTFS file systems?

Jeff
