For days I've been reading www.bayour.com/LDAPv3-HOWTO trying to setup my kerberos realm. I know those instructions are very good for people who're familiar with networking, but I'm over my head here because I am missing some vital basic understanding. Could someone please refer me to a source for beginners or if there's quick answers help me along?
The instructions in the above document state that I need to setup ldap and kerberos servers in my DNS like the following.
---- snip -----
; IP address to the Kerberos/LDAP servers
kerberos IN A <IP ADDRESS OF YOUR 1st KERBEROS SERVERS>
kerberos-1 IN A <IP ADDRESS OF YOUR 2nd KERBEROS SERVERS>
ldap IN A <IP ADDRESS OF YOUR 1st LDAP SERVER>
----------- snip ----
But I only have one IP address provided to me by my ISP. So do I enter that one IP address for all of the servers?
To setup kerberos realm name I need to use my domain name. Is that the domain name found in /etc/resolv.conf?
Can I just use localhost.localdomain to setup a kerberos realm name and skip setting up DNS for kerberos and ldap servers, if I want to use kerberos in my local domain only?
