(I found this when searching for an answer)
“Boot the system from CD1 of Red Hat Linux. At the prompt enter “linux rescue”. Severel dialog box appear. Press “ok” on these boxes. At the end you will get a shell prompt. In the shell prompt enter “chroot /mnt/sysimage” and next enter
“passwd”. This will ask for your new password. Enter new password. Exit from the shell by entering “exit”. Eject your
CD1 now. Now booting starts from hard drive.”

(I tested this with Redhat 8 and it works great.)
When using AppleShare or AFP to access network resources and you disable “allow cleartext passwords” you are then unable to access network resources that use AFP because you have to leave cleartext passwords enabled. To Fix this problem simply type this command in at the termainal window:
rm ~/Library/Preferences/.GlobalPreferences.plist
After this file is deleted reboot and you should have the option for cleartext again.
This is the problem I was getting which caused me to do some investigating. I would get a bad username and password error without it even trying to authenticate.
