Can you try and reproduce this against 4.1.latest please ? We did some fixes in this area, and if it doesn't fail there, then we can find out what got fixed and maybe help identify it for you.

Jeremy.

HI Jeremy,

Currently we are running SAMBA 3.6.12 as part of our product, and we are planning to upgrade 4.1 soon. In the mean time if there any fix available against 3.6.X would be really helpful.

closing, this is not an issue in more modern versions.
