This will be a scratch space for the beginning of new Kerberos & LDAP page. Initially, this will be a bunch of random notes, hopefully coalesced into a document.

[edit] Things that can use Kerberos / LDAP to authenticate
These are the things that we would like to use our K&L auth:
- NFS4 authentication/security
- automount / autofs
- sudo
- ssh / kerberos key forwarding / ldap shared keys?
- Apache web page security
- Netgroups -- limiting logins to specific machines
- AFS -- andrew file system
- radius / 802.1x for wired and wireless networks
- Samba -- be able authenticate windows clients -- perhaps using pgina.
- Mac OS/X clients?
[edit] First setup DNS
Kerberos and to a lesser extent LDAP need to have proper DNS names. If you are using an internal network (192.168.x.y), you will need to setup a DNS for your network.
The topic of DNS is very large. I'm not going to cover it here. I should point you to some external document.
I've found that on RHEL5/CentOS5 you can use system-config-bind. The help is good. I just imported the /etc/hosts file as suggested. This worked very well!
Also, one can use DNS service records to automatically find both the kerberos KDC and the ldap server.
[edit] Setting up Kerberos
yum -y install krb5-server
edit /etc/krb5.conf edit /var/kerberos/krb5kdc/kdc.conf
/usr/kerberos/sbin/kdb5_util create -s (can redirect input)
edit /var/kerberso/krb5kdc/kadm5.acl make it look like
