Ovirt devel - Jan 2009 - Questions about search feature and adding users

Hey guys,
  Search feature seems not well. For simple example,I even can not use 
it to search a hardware pool. Right?
  And,User Access feature, I can create  users of  one named 
"Administrator(admin)" and a null user. Then,I cannot create any more.
  The user name is fixed up. How can I create more users?
