[Samba] Samba Wiki Correction DHCP

[Sami Hulkko]

Hi,

In section Configure DHCP to update DNS records - SambaWiki 
<https://wiki.samba.org/index.php/Configure_DHCP_to_update_DNS_records> there 
is offered a script for DHCP to DNS auto uptate that should have 
addendum. According to  RFCs, including RFC 1035 and RFC 1123 DNS labels 
can not have special characters have space or start with hyphen.

In section:

....

# exit if name contains a space
case ${name} in
     *\ * )
         logger "Invalid hostname '${name}' ...Exiting"
         exit
         ;;
esac

....

One should add these cases.
