Is everything in / ?
Yes
so looks my fstab:# <file system> <mount point> <type> <options> <dump> <pass>
proc /proc proc nodev,noexec,nosuid 0 0
# / was on /dev/md1 during installation
UUID=3f9a2ca7-21a3-40d6-9d43-06d0334c494a / ext4 user_xattr,acl,barrier=1,errors=remount-ro 1 1
# swap was on /dev/md0 during installation
#UUID=b1f620f6-4763-48c4-a45e-f7ab56e8d398 none swap sw 0 0
/dev/mapper/cryptswap1 none swap sw 0 0
Can you read some problems here that can affect my permissions?Can I edit fstab like this?UUID=3f9a2ca7-21a3-40d6-9d43-06d0334c494a /home/Shares ext4 user_xattr,acl,barrier=1,errors=remount-ro 1 1
You probably don't need a 20GB swap partition.

As I said, it is a personal thing not put anything into /usr/local/samba
other than what samba puts there it self, also I said you don't need any
permission settings in the share configuration i.e. directory mask = 0777

No, it is not a requirement, it is your AD DC, you can do what you like,
I can only advise, I cannot and would not demand you do anything. I
personally use /home (on a separate partition) for two main reasons, I
can easily upgrade/change the OS without losing the contents of /home
and I can easily back it up.

If you use the wrong tool to back up /home for instance, when you come
to restore from this backup, you may find all the permissions are
screwed up or totally missing. Early versions of tar know nothing about
ACLs, later versions have the '--acls' & '--xattrs' switches.
