Have you tested adduser seperately? I can't see any problem with your
code, suggesting it may be adduser.

You can do inline tuple unpack:

  for userid, password, name in c:

>     aList.append("%s::20::::%s::sh:%s" %(userid, name, password))

Just in case you hadn't noticed the shortcut here:

   for userid, password, name in c:
      f1.write("%s::20::::%s::sh:%s\n" %(userid, name, password))

> f1.close

Ahah! Where are the parenthesis? :)  Your file is probably not getting
flushed to disk:
