[Samba] Samba on AIX, issues setting read-only flag on files through Windows Explorer?

Tue Mar 31 08:32:56 MDT 2015

Here is also the log from Samba with logging level 3 trying to debug this read-only flag issue...

In the below log (i did some cut/paste to minimize its size) we can see the creation of the file on the samba share, renaming it to "testing.p" and changing its properties...

Setting its read-only flag: unix_mode(testing.p) returning 0544
Removing the read-only flag: unix_mode(testing.p) returning 0744

Then we login to the unix box, change file owner to someone else and try to set the read-only flag again we get...

unix_mode(testing.p) returning 0544
smb_set_file_dosmode: file_set_dosmode of testing.p failed (Operation not permitted.)
mirde closed file testing.p (numopen=2) NT_STATUS_OK

So there is some kind of error happening under the stack when trying to change the read-only permissions on a file of which I am not the owner, but part of the same group that the file is owned by..

Anyone have any ideas?
