The username, I'm guessing, is in the POST payload. Example:

username=foo&password=bar

So something like this might work to extract the username from that data: 


when HTTP_REQUEST {
     if { [HTTP::method] equals "POST" } {
          HTTP::collect [HTTP::header Content-Length]
     }
}
when HTTP_REQUEST_DATA {
     if { [HTTP::payload] contains "username=" } {
          foreach x [split [HTTP::payload] "&"] {
               if { $x starts_with "username=" } {
                    set username [lindex [split $x "="] 1]
               }
          }
     }
}
