[Samba] DOS programs unable to create files on Samba 2.2.7a

[Arne R. van der Heyde]

We have a few old DOS programs which, when run under Windows 2000 is a 
DOS full screen session are unable to write files on our Samba server. 
These programs (the "brief" editor, and the "tango" CAD package) are 
able to write to local files on the Windows 2000 system. I set Samba 
debug to 10 and found the following reported when Tango tried to write a 
file:

*************************

As you can see, "Operation not supported" is returned when Samba tried 
to create the file. Unfortunately this does not give me much of a clue 
as to why the Operation is not supported. I suspect that the mode/flags 
may provide a clue but I have not been able to determine what they mean 
in this function. Hopefully someone familiar with their meaning will be 
able to tell me why this file create was rejected. Also, is there a 
Samba setting which would allow me to work around this and allow these 
old DOS programs write to the Samba server?
