samba - Mar 2016 - Samba 4.1.12 NT_STATUS_ACCESS_DENIED messages

We used successfully samba 3.5.15-74.fc15 in our production (animation studio).
It was installed on FC15 on ext4 volume.
Now, we got new hardware and tried fresh software installation:
it is CentOS7, with Samba 4.1.12 and XFS volumes.
So, now we got strange problem. Some production software (Autodesk Maya2016) got
errors trying to work with files. There is no such problem with Samba3.
For instance, we want to get software render - i.e. generate some files on samba
share. But we got error message with “permission error” in Maya log. The files
appeared in appropriate folder, but all of them are truncated - about 100 byte
length instead of hundred of bytes. The very strange moment, that this error
depend on file type to generate. .iff files are ok, but most all others (png,
tiff, psd) - generates errors.
Samba log files contains some NT_STATUS_ACCESS_DENIED messages. But all the
files are available from clients and there is no problem to create folder\files
as the software requires.
What may be the reason? How can we solve that?

Hi,

Lot of things can be the reason, or the reasons. More information are
needed to start thinking about your issue. Giving us your configuration
files, OS on client, logs (not the whole logs but neither just
NT_STATUS_ACCESS_DENIED), and anything else which could help one of us to
understand better your issue, for that person can try to help you.

As a lazy poster I could suggest to get more recent version of Samba.

Sorry to not help more than that...

Mathias

i ask myself from where he got Samba 4.1.12 on CentOS7
a simple typo makes 4.2.1-3 not to 4.1.12

samba-4.2.3-12.el7_2.x86_64
