sudo chown nobody.nogroup should be sudo chown nobody:nogroup

Thanks.

Master file Reference: samba.xml line 197
<command>sudo chown nobody.nogroup /srv/samba/share/</command>

While we are at it, we should also fix master file lamp-applications.xml line144
<command>sudo chown -R www-data.www-data mywiki</command>

By the way, using a "." instead of a colon actually does seems to work. Example:

doug@s15:~$ ls -l zzzxxx
-rw-rw-r-- 1 doug doug 62 Oct 11 07:53 zzzxxx
doug@s15:~$ sudo chown www-data.www-data zzzxxx
doug@s15:~$ ls -l zzzxxx
-rw-rw-r-- 1 www-data www-data 62 Oct 11 07:53 zzzxxx

From "info chown":

"Some older scripts may still use ‘.’ in place of the ‘:’ separator. POSIX 1003.1-2001 (*note Standards conformance::) does not require support for that, but for backward compatibility GNU ‘chown’ supports ‘.’ so long as no ambiguity results. New scripts should avoid the use of ‘.’ because it is not portable, and because it has undesirable results if the entire OWNER‘.’GROUP happens to identify a user whose name contains ‘.’."
