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

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

Recommended Links Selected PAM Modules strace Reference Linux PAM Solaris PAM PAM wheel SecurID Humor Etc This nasty Suse and Red Hat error actually can have different (and sometimes multiple) reasons. It does not prevent successful authentication, but makes changing password via passwd impossible. You still can "implant" password from the other server in /etc/shadow file manually to bypass the error (servers should have identical encryption method set). Often this error arise due to problems with shadow file. For example shadow password file doesn’t have entry for this user. i.e, /etc/passwd has an entry for this user, but /etc/shadow doesn’t. The checklist below might help to structure your troubleshooting efforts. Checklist the "Authentication token manipulation error" Is this problem for a particular account or all accounts including root. Are you using something like NIS or LDAP? Try grep passwd /etc/nsswitch.conf Running system-config-authentication you can configure the pam settings for the files located in /etc/pam.d. Does the user exists in /etc/passwd and /etc/shadow. Are attributes of those files correct. Should be: /etc/passwd root.root -rw-r--r-- /etc/shadow root.root -r-------- Check if the passwd command has the SUID bit enabled and it's owned by root.root. Check integrity of package which contains passwd. rpm -qf passwd pwdutils-3.0.7.1-17.24 rpm -V pwdutils Are records for the user valid (many be accidentally corrupted by manual editing, extra or missing colon is pretty common problem in this case). If passwd and group file were copied from other server, often shadow and gshadow files are not in sync. Try to delete and re-create user records using useradd to make sure that all account records are in sync and valid. Are permissions on /etc/passwd and /etc/shadow correct Were PAM configuration changed ? What are exact messages in /etc/log/messages. Get strace for the problematic system and strace both for the same user on the system that works OK and has the same PAM configuration. Compare failed and successful straces and find the point at which they diverge. Add debug option to relevant modules in PAM and see if they will provide any useful additional diagnostics. Try to simplify PAM excluding modules one by one. pam_securid.so is known to cause this error is you put it in a wrong place (for example in common_passwd on SUSE) Some Usenet posts suggest that pam_cracklib.so might cause problems t
