actually, I'm surprised that you didn't notice a burp when you used
chown command as the Red Hat tools will use a dot as a separator. 


chown craig.dom_users /path/to/file
chown craig:dom_users /path/to/file

are functionally the same thing but just because it doesn't toss an
error the first time you 
  chown this.is.a.very.long.username /somefile
doesn't mean that it actually worked. If you did 
  "chown this.is.a.very.long.username" /somefile
it probably would work

I would suggest that you keep testing for adequacy.
