Puppet users - May 2013 - Failed to set owner to: integer too big to convert to `int'

When trying to execute the code bellow I get this error:

err: 
/Stage[main]//Node[ftp.example.com]/Addclient[uniqueID]/File[/PATH/inbox]/owner:
change from 2279892064 to 2279892064 failed: Failed to set owner to 
''2279892064'': integer 2279892064 too big to convert to
`int''

This code works for anything that doesnt exceed the max size of an integer 
but when you do the error above pops up. (example number 2279892064)
I am trying to keep the username a string throughout but somewhere along 
the line puppet is trying to convert it into an integer. 

Has anyone else experienced this and have a potential fix?

Thanks in advanced. 

How I call the Code:
    addclient { "uniqueID": username => "2279892064", uid
=> ''7057'', home
=> ''/PATH/'', password =>
''$1$30P5Lb0M$2Ut3TkD91cd4GtTO5PVnx0''; }

Code:
define addclient ( $username='''', $uid='''',
$shell=''/sbin/nologin'' ,
$home='''', $password='''',
$groups='''' ) {
    user {
        "$username":
            uid         => $uid,
            gid         => ''7005'',
            allowdupe   => false,
            shell       => $shell,
            home        => $home,
            password    => $password,
            groups      => $groups,
            ensure      => present;
    }

    file {
        "$home":
            ensure  => "directory",
            require => User["$username"],
            owner   => root,
            group   => root,
            mode    => ''755'';

        "$home/inbox":
            ensure  => "directory",
            require => User["$username"],
            owner   => "$username",
            group   => "sftponly",
            mode    => ''775'';

        "$home/dropbox":
            ensure  => "directory",
            require => User["$username"],
            owner   => "$username",
            group   => "sftponly",
            mode    => ''775'';
    }
