(current) Unix Password Passwd Authentication Token Manipulation Error
Answers 4 active oldest votes up vote 137 down vote accepted Also make sure you are mounting the file system read/write. 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. –Somebody Apr 7 '14 at 16:54 1 even after following these steps it will not accept my password –angela Aug 14 '14 at 15:09 2 Odd. mount showed that / was already mounted as read/write, but mount -rw -o remount / still worked. No idea why. –Hubro Dec 2 '15 at 9:11 Thanks a lot for your help! –Love Jun 13 at 13:53 i am simply one of those idiots who did not read the stdout and forgot to put in the "(current) Unix password" but the password that I want it to be :( –B.Mr.W.

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 th
Date: Mon, 27 Mar 2006 16:24:54 +0200 Hello, I've got the following situation: The 6000 accounts of our eMail-server are stored in /etc/passwd resp. /etc/shadow. To change https://www.redhat.com/archives/pam-list/2006-March/msg00017.html their passwords, the users use a ssh-session. The only object of the ssh-session is to change a users password, therefore the loginshell is /usr/bin/passwd. To avoid attacks on the ssh-daemon, we only want a seperate web-server with a little php-web-page to open the ssh-session. I use apache/php with a php-module called php-ssh2 and a library called authentication token libssh2 to establish the ssh-session. This works fine, until it comes to the point, where the old password is sent to /usr/bin/passwd. I get the following screen in /var/log/messages: sshd[]: pam_unix2: pam_sm_authenticate() called sshd[]: pam_unix2: username=[dummy] sshd[]: pam_unix2: pam_sm_authenticate: PAM_SUCCESS sshd[]: pam_unix2: pam_sm_acct_mgmt() called sshd[]: pam_unix2: username=[dummy] sshd[]: pam_unix2: expire() returned with 0 sshd[]: Accepted password for authentication token manipulation dummy from 192.168.136.50 port 6235 ssh2 sshd[]: pam_unix2: session started for user dummy, service sshd sshd[]: pam_unix2: pam_sm_setcred() called sshd[]: pam_unix2: username=[dummy] sshd[]: pam_unix2: pam_sm_setcred: PAM_SUCCES -passwd[]: pam_unix2: pam_sm_chauthtok() called -passwd[]: pam_unix2: username=[dummy] sshd[]: pam_unix2: pam_sm_setcred() called sshd[]: pam_unix2: username=[dummy] sshd[]: pam_unix2: pam_sm_setcred: PAM_SUCCESS sshd[]: pam_unix2: session finished for user dummy, service sshd -passwd[]: pam_unix2: pam_sm_chauthtok() called -passwd[]: pam_unix2: username=[dummy] -passwd[]: User dummy: Authentication token manipulation error -passwd[]: password change failed, pam error 20 - account=dummy, uid=1000, by=1000 If I use some other tools like gnu-ssh or putty, it all works very well. Is there a difference between the two methods gnu-ssh and PHP-script, which /usr/bin/passwd recognizes, e.g. keyboard-interactive vs. tunneled-cleartext? I think of this, because I had to change some settings in /etc/ssh/sshd-config, to enable tunneled-cleartext authentication: PasswordAuthentication yes enable or disable following in sshd-config has no effect: ChallangeResponseAuthentication no UsePAM yes What does that mean: 'Authentication token manipulation error'? Is it possible to use /usr/bin/passwd with a pipe, like libssh2 does? The PAM configuration is mostly Su
