Setting it up was as easy as a single command line: authconfig \ --usemd5 --useshadow --enablelocauthorize \ --enablekrb5 \ --krb5realm={AD Domain Name} \ --enablekrb5kdcdns --enablekrb5realmdns --update This makes the necessary changes to /etc/krb5.conf, /etc/ and /etc/nsswitch.conf. I am NOT using this for user information, just password authentication, so I add user accounts for each authorized user. You can also consider using the --disablesysnetauth flag, which disables authenticating "system" accounts via the network services and forces them to use local authorization. This should prevent entries in the AD for "root" and other system accounts from being used. Hope that helps! -- Jay Leafey - Memphis, TN jay.leafey@xxxxxxxxxxxx
