[Samba] access denied for ms office documents on samba 4.1.17 ubuntu 12.04

[Tadewos Alemneh]

I’ve posted earlier a question related to the problem regarding MS Office Documents that are saved in share folders on samba 4.1.17.
Samba 4 is installed and configured as AC DC on Ubuntu 12.04 server. All share folders are accessible to the respective users with respective rights.

The problem is, some Office Documents at times will not be accessible even to file creators, owners. This happens at least once a day.

When I login as an administrator and check the rights of users on those documents, I found that all users who have been give full right, have lost their rights on those documents but folders. This happens only by office documents and sometimes by some files that are downloaded from Internet and from e-mail saved attachments. Until now, I didn’t find any solution to this problems.

Now I’ve noticed that the problem appears when different users (more than one user) work on the same office file irrespective of the time when the users accessed the documents. By Documents that are owned and accessed only by one and same user (creator) there was no such problem. Is there anything that I can do to fix it?

Thank you
