Re: New Cygwin 1.7.0-18 in release-2


-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

According to Corinna Vinschen on 7/17/2008 9:55 AM:
| Hi,
|
| again I would like to encourage the Cygwin maintainers, to try the new
| Cygwin 1.7.0 release and to look for problems in their packages which
| might be a result of the fairly massive changes in Cygwin 1.7.  I
| attached a list of the changes below.  The latest changes are:
|
| - Changes in mkpasswd/mkgroup and in seteuid() should result in more
|   correct user tokens in AD domains.  Try the LSA module.
| - Case-sensitivity on NTFS and NFS and mount option "posix=[0|1]".
| - Remove CYGWIN=ntsec and CYGWIN=smbntsec options in favor of a mount
|   option "acl"/"noacl".

Somewhere between setting obcaseinsensitive to 0 yesterday and upgrading
to the new cygwin1.dll today, I'm now suffering from an inability to
modify files on a shared drive on my work machine.  I can create empty
files and remove existing files just fine, but get access denied on any
attempt to change contents.  The -1 for owner and group looks fishy as well.
