Ref to forum thread https://forum.rockstor.com/t/wrong-tagging-in-smb-conf/2418 by user g6094199:
There's a minor "bug":
Samba AD Configuration closing tag has "BEGIN" instead of "END"
This doesn't raise any error and/or unexpected behaviour, one line fix coming now
Fixes #1548, closing tag now has END instead of BEGIN
