[Samba] Ubuntu client ddns failure [SOLVED]

[L.P.H. van Belle]

and 

The GNU C library does not  employ the  gethostname()  system  call;
instead, it implements gethostname() as a library function that calls
uname(2) and copies up to len bytes from the returned nodename field
into name. 

so no search but library function that calls.. 
therefor make sure the base is set correct. 

if not set correct search and a library function calls can give different results. 

read : 
http://manpages.ubuntu.com/manpages/precise/man2/gethostname.2.html 
http://manpages.ubuntu.com/manpages/precise/man2/uname.2.html 
see uname note on that page.
