I don't remember answering any questions.  If there were any they must have been 
pretty inocuous (sp?) looking. Most of the time I was out of the room!  I can't 
ftp to or from the box at the moment so I can't attach the logs but it appears that
something has happend to corrupt /lib/security/pam_env.so
the following lines appear where I was trying to login to the newly created account.
Jun  7 20:07:20 adler login[17328]: PAM unable to dlopen(/lib/security/pam_env.so)
Jun  7 20:07:20 adler login[17328]: PAM [dlerror: /lib/security/pam_env.so: invalid ELF header]
Jun  7 20:07:20 adler login[17328]: PAM adding faulty module: /lib/security/pam_env.so
Jun  7 20:07:30 adler login[17328]: FAILED LOGIN (1) on `tty2' FOR `jan', Module is unknown
It looks like I have either picked up a corrupted file or the hard drive is on the way out.
