Cygwin + Samba = Permission Denied

Fri Apr 12 16:08:00 GMT 2002

Turning to the mailing list as a last resort...
The problem:
cygwin-bash$ cp foo.txt //sambamachine/share/
cp: cannot create regular file `//sambamachine/share/foo.txt': Permission denied
various unsuccessful mailing list and Google searches turned up only
this, from Corinna:
http://sources.redhat.com/ml/cygwin/2001-04/msg01210.html
in which she advises getting the MAHINE.SID and setting up your
Cygwin /etc/passwd to match etc etc. Unfortunately, none of that
worked.
An strace reveals:
 65 285333 [main] cp 1088 fhandler_base::open: (\\sambamachine\share\foo.txt, 0x201)
 127 285460 [main] cp 1088 alloc_sd: owner: ryans [2136]
 828 286288 [main] cp 1088 alloc_sd: ACL-Size: 100
 74 286362 [main] cp 1088 alloc_sd: Created SD-Size: 176
 1115 287477 [main] cp 1088 fhandler_base::open: 0xFFFFFFFF = CreateFileA (\\sambamachine\share\foo.txt, 0x40000000, 0x7, 0x241F644, 0x4, 0x80, 0)
 119 287596 [main] cp 1088 seterrno_from_win_error: /cygnus/netrel/src/cygwin-1.3.10-1/winsup/cygwin/fhandler.cc:412 errno 5
 53 287649 [main] cp 1088 geterrno_from_win_error: windows error 5 == errno 13
windows error 5 == errno 13 == "Access denied".
Interestingly, on the samba machine, foo.txt IS created, but 0 length.
If I do *another* cp foo.txt //.... then it succeeds.
In cmd.exe, "copy foo.txt \\sambamachine\share\foo.txt" works fine, so I
know my samba passwords etc. are all good.
Any help appreciated.
