See the attached.  It is likely the above is the same problem.  If so,
then Pierre Humblet has a patch to correct this problem.

What is you gid?

    $ id -g
    513

If it is not 544, then edit your /etc/passwd so that it is.

Pierre,

The following change breaks proftpd:

    http://cygwin.com/ml/cygwin-cvs/2003-q3/msg00237.html

By "breaks", I mean the following failure occurs when a user attempts
to authenticate:

    C:\Cygwin\usr\sbin\proftpd.exe: *** CreateFileMapping, Win32 error 5.  Terminating.

I was able to workaround and isolate the problem with the attached
"patch" -- that is reverting to the old behavior.

Any ideas on how to fix the problem correctly?

Thanks,
Jason
