Insided the ssl tunnel the password is being sent as a "clear text string". Using Webscarab like a mntm attack, I can clear see the user name and password.
If I used wireshark to sniff the connection, you don't see anything since the tunnel is encrypted, I haven't tried dsniff, to see if that would help any.
I was thinking of trying netcat to see what it might happen.
Thanks everyone for all the help and information.
Take Care --John
