Some days ago I had this bug. And I had traced, how to 'net ads' works. This 
error will throw, when 'net' try to set principals HOST/hostname and 
HOST/hostname.domain.tld. First, it take macine name and create 
HOST/hostname. Second it call my_fqdn() to convert machine name to fqdn, BUT 
(!!) it uses only /etc/hosts here! No nsswitch, no gethostyname(). So, check 
your /etc/hosts - probably here is wrong record.
