After immediately selecting 'Drop into root shell prompt' I found the filesystem was mounted read only, which prevents resetting the password. Choosing the option to remount / as read/write and going back into the root shell prompt enabled the password change. The command to run prior to changing the password is: mount -rw -o remount / share|improve this answer edited Apr 29 '12 at 14:39 Community♦ 1 answered Jan 3 '12 at 23:29 Brandon 1,386172 Thank you, that worked. –Some

when changing PW in Ubuntu? Anthony J https://linuxacademy.com/community/posts/show/topic/1881-explain-authentication-token-manipulation-error 02-17-2015 HI "New" it is because you are not entering the "current" password that it is asking for instead you are entering http://unix.stackexchange.com/questions/80138/avoid-authentication-token-manipulation-error-on-password-change your desired new password. For example.. When you enter in not the correct "current" password which by default is 123456 user@anthony4:~$ su Password: authentication token You are required to change your password immediately (root enforced) Changing password for root. (current) UNIX password: su: Authentication token manipulation error user@anthony4:~$ When you enter the correct one: user@anthony4:~$ su Password: You are required to change your password immediately (root enforced) Changing password for authentication token manipulation root. (current) UNIX password: Enter new UNIX password: Retype new UNIX password: root@anthony4:/home/user# You can see that it is asking for the "current" password first to verify you are who you say you are.

The default common-password file comes with this two lines: password requisite pam_pwcheck.so nullok cracklib password required pam_unix2.so use_authtok nullok I need to add several options to the pam_pwcheck (no problem with that) and another PAM module (pam_cracklib) to make the passwords stronger. Next, it is my final /etc/pam.d/common-password file, included from passwd: password requisite pam_cracklib.so minclass=3 retry=3 password requisite pam_pwcheck.so nullok cracklib minlen=10 remember=5 password required pam_unix2.so use_authtok nullok My problem occurs when I have both PAM modules configured: if I introduce a correct password, it works fine. If I introduce a bad password that must be rejected by pam_cracklib (for example, a password with only lower case letters), it works fine (rejects the password without problem). But when I introduce a password that is valid for cracklib but not for pwcheck (a password with upper case, lower case and numbers of 7 characters length), it rejects the password, but this error is shown: Bad password: too short passwd: Authentication token manipulation error So, pam_pwcheck print its error message (Bad password: too short), but something bad happens with the PAM chain. Do you know what is wrong in my configuration? P.S. The "security" requirements are not mine at all, so please, avoid comments on it ;-). security password pam share|im
