1) You have tried several times I hope?
If not, just try again - maybe ther was a mismatch between your two passwords.
2) How about password requirements?
AFAIK that is most commonly set with PAM.
Check under /etc/pam.d/ (or whatever GUI-tool there might be for this).
3) Are all accounts local, or do you use an authentication system (AD, LDAP etc)?
