I am using krb5 authentication to authenticate users in my machine. I am trying to change my password using passwd command but it failed. 

~:$ passwd
~:$ Changing Password for bharathi
~:$ Kerberos 5 Password: 
~:$ New Password: 
~:$ Retype new password: 
~:$ authentication error

Syslog Output

pam_krb5  password changed failed for bharathi: Authentication error : Authentication error
pam_unix(chauthok): authentication failure: loginname=root uid=3310 euid=0 tty=pts/36 ruser= rhost= user=bharathi
pam_unix(chauthok): user password changed by another process

I cannot reset my password. Please help.

you need kpasswd to change a kerberos password.

This could help you: http://manpages.ubuntu.com/manpages/natty/man1/kpasswd.1.html
