define Package/samba4/description
  The Samba software suite is a collection of programs that implements the
  SMB/CIFS protocol for UNIX systems, allowing you to serve files and printers.

  Samba4 implements to the latest SMB v3.1.1 version, supports mDNS via AVAHI and a AD-DC setup via krb5.
  NOTE: Without Cluster and printer support.
