The session id is stored in a cookie, so if a user comes to your site
without a cookie and you are using %udat, Embperl will create a new session.
Embperl cannot know that this is the same user.

You have store the session id of the user somewhere and is the users logs in
the second time you can retrieve the old session id and delete it.
