Configuration Guide for Kerberos Client Products on HP-UX

Sample krb.realms File
Appendix D116
Replace the underlined Your_Realm_Name,
Your_Primary_Security_Server, Your_Secondary_Server_Server
and Your_Domain_Name with the name of your Kerberos REALM, primary
and secondary servers hostnames.
Your_Primary_Security_Server Your_Realm_Name #
.Your_Secondary_Security_Server Your_Realm_Name
#
*.Your_Domain_Name Your_Realm_Name
#
Given below is an example with a brief explanation of the krb.realms
file.
deer.bambi.com BAMBI.COM # map host directly
.fox.bambi.com BAMBI.COM # all hosts in domain
*.bambi.com BAMBI.COM # all the other hosts belonging
to the domain and sub-domains
Line one of the krb.realms file maps the host admin.bambi.com to the
BAMBI.COM realm.
Line two of the krb.realms file maps all hosts in the fox.bambi.com
domain to the BAMBI.COM realm.
NOTE The preceding dot in this line identifies the first field as a domain name
rather than a hostname.
Typically, this line is not required as the realm name, by default, is the
upper-case equivalent of the domain name.
Line three of the krb.realms file maps all hosts in the domain and
sub-domains with the root name bambi.com to the BAMBI.COM realm.
