We have noticed the same thing in CentOS 7.  The setgid no longer works
like it did before, so now we create our shares like this following the
instructions from the wiki.

https://wiki.samba.org/index.php/Setting_up_a_Share_Using_POSIX_ACLs


# chmod 700 /u01/test
# chown root:root /u01/test
# setfacl -m group::--- /u01/test
# setfacl -m default:group::--- /u01/test
# setfacl -m other::--- /u01/test
# setfacl -m default:other::--- /u01/test
# setfacl -m group:unixadmins:rwx /u01/test
# setfacl -m default:group:unixadmins:rwx /u01/test


smb.conf

 [test]
  comment = test
  path = /u01/test
  read only = No
  inherit acls = yes
