You can either do this graphically (system-config-authentication) or via command line (authconfig).
When doing it with the command line, it can be hard to remember all the parameter, but with help of '--help' it is easier.
The LDAP parameters
The Kerberos parameter.
And finally SSSD (System Security Services Daemon), which enable cached authentication, which in turn means enabled off-line authentication. Which both can be good and bad. An unstable network connection does not stop you for logging in. But you also need to remember that authentication data might be stale.
Lets put all this together and add --update at the end to update authentication configuration.
