I did not check whether our user is correct about the default for this setting being "no" so I report this bug as it has been reported in Debian BTS:
The man page of smb.conf says that
Default: store dos attributes = yes
This is wrong. This option is at no by default.
Created attachment 2402 [details]
Patch to the original XML file
The attached patch to the samba-docs/trunk/smbdotconf/filename/storedosattributes.xml file should fix that minor bug
Fixed in rev 1114. Thanks :)
