Appendix C Sample krb.realms File

The sample krb.realms file named krb.realms.sample is available in the /opt/krb5/examples directory. You can copy this sample file to the /opt/krb5 directory, and modify it to reflect your realm name.




	NOTE: The realm names are case sensitive.

Replace the underlined Your_Realm_Name, Your_Primary_Security_Server, Your_Secondary_Security_Server, and Your_Domain_Name with the name of your Kerberos REALM and host names of the primary security server and secondary security servers.

Your_Primary_Security_Server Your_Realm_Name     
.Your_Secondary_Security_Server Your_Realm_Name  
*.Your_Domain_Name Your_Realm_Name

The following is an example of the krb.realms file with a brief explanation:

admin.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 subdomains

The first line of the krb.realms file maps the host admin.bambi.com to the BAMBI.COM realm.

The second line 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 host name. Typically, this line is not required as the realm name. By default, is the upper-case equivalent of the domain name.

The third line of the krb.realms file maps all hosts in the domain and subdomains with the root name bambi.com to the BAMBI.COM realm.
