Bug description

$ enum4linux -u xxx -p xxx -S x.x.x.x

1. The script is looking for polenum.py but polenum is in the PATH

   $ which polenum
   /bin/polenum

2. ldapsearch is part of openldap: missing dep
3. /etc/samba/smb.conf doesn't exist by default. see https://wiki.archlinux.org/index.php/Samba, so a post-install step with an echo is needed to warn the user 4./bin/enum4linux: no clue

After creating /etc/samba/smb.conf, an another error occurred:

mkdir failed on directory /var/cache/samba/msg.lock: Permission denied
