Allows you to use a Kerberos password when authenticating to SSH, sudo, and other PAM aware programs.  Will fall-back to local authentication if that fails.

This package installs both pam_KFM (for checking your Kerberos password) and pam_securitysession (to not carry over your existing credentials when you su or sudo).

man pages for pam_KFM.so and pam_securitysession.so will be installed if you'd like more information.
