KERBEROS_V4 rejected as an authentication type

admin

uess: in RHEL 5, rsh, rlogin and ftp clients will attempt first to use Kerberos, then fall back to classic methods. In this case, this is not an error, but an informative message, reminding you that your password will be sent to the server in unencrypted plaintext.

To stop your system from trying to use Kerberos, remove /usr/kerberos/bin from your PATH: this directory contains Kerberos versions of ftp,rcp,rlogin,rsh and telnet.

In RHEL5, this can be done by moving the krb5-*.sh and krb5-*.csh files away from /etc/profile.d directory:

mkdir /etc/profile.d/disabled
mv /etc/profile.d/krb5-*sh /etc/profile.d/disabled
This change will take effect at the next user session, so you may have to logout & login, then restart the ControlM agent (if you use one).
