produced because you are using shadowed password files and the shadow doesn't have entry for this user. i.e, authentication token manipulation error raspberry pi /etc/passwd has an entry for this user, but /etc/shadow doesn't. In order to resolve this, you can either add the entry manually or recreate the shadow file. You can http://askubuntu.com/questions/57620/getting-an-authentication-token-manipulation-error-when-trying-to-change-my-us use pwconv to recreate the shadow file.

I was using https://mohammednv.wordpress.com/2008/01/08/authentication-token-manipulation-error-when-changing-user-passwords-in-linux/ PAM and the command "chage -d 0 username" to force the user "username" to change his/her password at his first log on. Actually, what I am going to mention here is *not* an error, but a mistake from my side. When you use PAM and the above command it will ask for the present password twice. First one as usual, and second time when you are being forced for the password change. When I entered the first one correctly and the second one wrongly, I got this error.

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.
