## I have the followind definitions
Exec {
  path => "/bin"
}

define database($admin, $user) {
  db_create { $title : }
  db_grant { "$admin@$title" :
    db => $title,
    user => $admin,
    grant => ALL,
    require => [ Db_user[$admin], Db_create[$title] ]
  }
  db_grant { "$user@$title" :
    db => $title,
    user => $user,
    grant => DCL,
    require => [ Db_user[$user], Db_create[$title] ]
  }
}

define db_create {
  exec { "echo $title": }
}

define db_grant($db, $user, $grant) {
  exec { "echo $title": }
}

define db_user($password) {
  exec { "echo $title": }
}

##Now I can use the following to create a database and grant users access:

database { "testdb":
        admin => "dbadmin",
        user => "dbuser"
}

db_user { "dbadmin": password => "foo" }
db_user { "dbuser": password => "foo" }


##But what I really want to do is:

database { "testdb":
        admin => "dbadmin",
        user => [ "dbuser1", "dbuser2", "dbuser3" ]
}

db_user { "dbadmin": password => "foo" }
db_user { "dbuser1": password => "foo" }
db_user { "dbuser2": password => "foo" }
db_user { "dbuser3": password => "foo" }
