Description Colin Coe 2009-06-01 19:38:39 UTC
Reproducable but only with GE ENMAC software.

I'm contracting with a utilities company that uses General Electric's
ENMAC software.  This runs on RHEL4 and makes use of Samba but it only
works with Samba 1.9.18p10 compiled with this patch:

 #include <sys/sem.h>
 #include <sys/shm.h>
-#ifdef NO_SEMUN
 union semun {
       int val;
       struct semid_ds *buf;

As I'm trying to streamline the building of these servers, I thought
I'd try upgrading Samba to a reasonably current version.  I'm trying
with latest version of Samba shipped by RedHat (3.0.33-0.17.el4), also tested with Samba v3.3.4.

When an edit is made and then saved in the application, the
application responds with 'Failed to open file for writing' and on the
Samba server a zero length file of the correct name appears.  This
works just fine with the patched Samba 1.9.18p10.

Can you attach a debug level 10 log from smbd showing the problem ? If you could also add your smb.conf, and let us know what filename is having the problem that would also help a lot.

bugzilla is made for bug reports mainly, to solve issues with that GE software you should try getting in contact with one of those companies offering commercial support: https://www.samba.org/samba/support/globalsupport.html
