UID problem

UID problem
I'm teaching myself UNIX, so bear with me! 
I created two user accounts on my box. One day I shut down the system using "shutdown -h 1". The system shut down cleanly.
A few days I rebooted the box, no problem.
But root is the only account that can log in. The other 2 user accounts can't.
CapsLock is off. Both accounts appear where they belong, with encrypted passwords. Fingering both accounts says they never logged in. If I SU to the first account it says it isn't there (grek sez it is), but I can SU to the 2nd account. And when I exit, it exits to the FIRST account that it said ain't there! From there I can exit back to root.
::shrug::
I also created two new accounts, and neither of them could log in, either. :/
And reassigning passwords doesn't work.
Help?

lppasswd
lppasswd(1) Apple Inc. lppasswd(1) NAME
lppasswd - add, change, or delete digest passwords. SYNOPSIS
lppasswd [ username ] lppasswd -a [ -g groupname ] username lppasswd -x username DESCRIPTION
lppasswd adds, changes, or deletes passwords in the CUPS digest password file, passwd.md5. When run by a normal user, lppasswd will prompt for the old and new passwords. When run by the super-user, lppasswd can add new accounts (-a username), change existing accounts (user- name), or delete accounts (-x username) in the digest password file. Digest usernames do not have to match local UNIX usernames. OPTIONS
lppasswd supports the following options: -g groupname Specifies a group other than the default system group. SECURITY ISSUES
By default, the lppasswd program is not installed to allow ordinary users to change their passwords. To enable this, the lppasswd command must be made setuid to root with the command: chmod u+s lppasswd While every attempt has been made to make lppasswd secure against exploits that could grant super-user privileges to unprivileged users, paranoid system administrators may wish to use Basic authentication with accounts managed by PAM instead.
