I am using Redhat Linux 5. I forgot the root password i set while installing linux OS. After rebooting right after the installation, entering root password is needed of course. So the following is what i did: I couldn't reset root password from "grub" after booting using single user mode. After writing command "passwd",instead of asking to input new unix password,it went like:
"changing password for user root. passwd: authentication token
manipulation error"
It skips the following
"Asking to input root password. Then it returns authentication token manipulation
error"
Any idea why it is doing so? This is the first time i do resetting root password via grub. The parameter i passed are "single" and "selinux=0" to disable SELINUX policy loading since it was halting when the SELINUX is not disabled.

@ctrl-alt-delor "Asking to input root password" was not the error. After using "passwd" command , it should ask me to input the new root password. But it didn't. Instead, it gives "authentication token manipulation error without asking me to give root password (reset password).

This answer assumes RHEL5 and also assumes that SELINUX is not enabled.
- At the boot loader (GRUB) menu select (highlight) the kernel you wish to boot into using the arrow keys if you have more than one kernel or OS menu item.
- Type A to enter into append mode.
- Press the spacebar once to add a space.
- Type the word "single" to tell GRUB to boot into single-user.
- Press enter and GRUB will boot you into single-user mode with root privledges.
- Now you can successfully run the
passwd rootcommand.

Did you edit the boot options and add init=/bin/bash to the boot entry?

@RamanSailopal , I now tried to append the boot entry by the following: 1) init=/bin/bash 2) then pressed enter 3) at bash prompt did : mount -n -o remount,rw / 4) Tried to reset password using "passwd" I am still getting the same error as the attach file shows above.

@ctrl-alt-delor "Asking to input root password" was not the error. After using "passwd" command , it should ask me to input the new root password. But it didn't. Instead, it gives "authentication token manipulation error without asking me to give root password (reset password).
