I installed and configured samba 4.2.0pre1 on this ubuntu server 12.04.2. It's purpose is to server as an PDC. During provisioning, I had to specify --use-ntvfs as option. However, i now read that s3fs is the default. Can i change to s3fs without reinstalling ? What is the best permission setting for a share on the linux server ? chmod 0777 and then do all the permission settings from an AD tool in windows ? Do these permission settings in linux have something to do with the samba filesystem ntvfs or s3fs ? Some howto's specify that you still have to use directory mask = 0777 and create mask = 0777 ? jef peeraer
