SMB share issue with macOS Sierra

[cpts]

Review /var/log/samba4/log.smbd and post any relevant information from when access 'drops'.

A little more googling and it looks like there's an issue with 10.12 Sierra where mount point ownership changes to root/wheel.

For what it's worth I took a look in log.smbd and all I could see were thousands of lines like the following:


[2017/05/21 21:02:42.788846, 0] ../source3/modules/vfs_fruit.c:986(ad_read_rsrc_adouble)
ad_read_rsrc_adouble: invalid AppleDouble resource Software/Virtualization/.AppleDouble/VirtualBox-4.2.18-88780-OSX.dmg

invalid number of entries: 13

ad_read_rsrc_adouble: invalid AppleDouble resource Software/Office/.AppleDouble/TextWrangler_4.0.1.dmg


I couldn't see anything else obvious. Is there a particular search string I can use?

I really think this is a macOS bug, and I've filed a bug report with Apple (though I won't hold my breath). I've seen apps designed to get around this issue and might give them a try. I have no problem accessing these same SMB shares from Linux (sorry if I left that out of the OP).

I ran into this same bug; filed a report and it was marked as duplicate, so Apple is aware. Since I've upgraded to High Sierra, I haven't seen it, but I've only been on High Sierra for a week. I did write an app to patch the bug called ConnectDrive.
