You'll need to boot into single user mode.
or possibly: http://www.google.com/search?q=singl...te:zentyal.org

If you boot into recovery mode you should automatically be logged in as root, so you just have to set a new password for your user with
Code:

passwd USERNAME
If that doesn't work please provide the exact error-message(s) you get.

Yes TobiSGD, its automatically direct me to root, but when i typed passws administrator, its give me this error below,
"Authentication token manipulation error"
password unchanged,

is it possible for previous administrator block this access or he protect & forbidden any user to change administrator password? because this server is handled by another administrator before

Thank you in advance

Check if the filesystem is mounted read only. Also check the permissions on /etc/passwd and /etc/shadow, maybe the immutable bit is set.
