To authenticate to the Kerberos realm at Indiana University (IU.EDU) using Gentoo Linux:

Note: You will need to be logged in as root for the following commands to work.

  1. Run the following command to install MIT Kerberos 5:
      USE="-krb4" emerge mit-krb5
  2. Run the following command to install pam_krb5:
      emerge pam_krb5
  3. Download the krb5.conf file at:
  4. Change the auth section of /etc/pam.d/system-auth to:
      auth required /lib/security/
      auth sufficient /lib/security/ likeauth nullok
      auth sufficient /lib/security/ use_first_pass
      auth required /lib/security/

When you attempt to authenticate, PAM will first check the local /etc/passwd file for the correct password. If this check fails, PAM will then perform a check against one of the Kerberos servers. If the Kerberos check is successful, you will be allowed to log in.

To log into a workstation, you must have an existing local account.
