The krb5.conf File—Configure Kerberos
The krb5.conf file tells Kerberos clients where the Kerberos server is on the network. On Linux and UNIX machines, krb5.conf typically resides on /etc.
The following krb5.conf file contains the minimum configuration for a Kerberos or Active Directory server on myHost.myDomain.com:
[libdefaults]
default_realm = MYDOMAIN.COM
[realms]
INGRES.PRV = {
kdc = MYHOST.MYDOMAIN.COM
admin_server = MYHOST.MYDOMAIN.COM
}
[domain_realm]
myDomain.com = MYDOMAIN.COM
.mydomain.com = MYDOMAIN.COM
Note: The Kerberos realm defined by MYDOMAIN.COM happens to be the same as the network domain name and extension, but the realm can have a different name.
