Messed up the OS

Today i was just playing with the smart cards on the sun blade workstations. I allowed smart card based login and lol the normal prompt for login was gone and it asked for the card. When i inserted the card (sobs) it said login failed. I had succesfully locked my self out of the sustem:(. anyways there are no plans to correct it as we are going to load solaris 10 on it.
