    Authentication token manipulation error


    Hi,

    I tried to change my password but all i was getting is

    passwd: Authentication token manipulation error
    passwd: password unchanged

    Any suggestion?

    Thanks

    are you running passwd as a regular user or as root? If as a regular user, your password may not be complex enough. If root, there is a bigger problem.

    To change the password of a regular (let's say "joeblow"), you can su to root and do:

    Code:
    echo "newpassword"|passwd --stdin joeblow
    that will set user joeblow's password to newpassword and you should be able to log in as that user w/that password immediately.

    sounds like your shadow file is screwed up, or something even lower level and more sinister.

    try this first:
    Code:
    pwconv
    that will try to fix the shadow file.

    if that doesn't work, check out your system logs:

    /var/log/messages
    /var/log/secure

    see if anything there gives you a specific error.

    Hi,
    pwconv is also not working.Nothing is there in /var/log/messages and there is secure file.

    Thanks

    Did you build this system from scratch or remove system files or something? You may need a reinstall...
