Configuration

krb.conf

 

The first line of the krb.conf file identifies the host systems default

 

realm.

 

The second line and its subsequent lines require fields that identify the

 

Security Server hostnames. Each field in line must be separated by a

 

space or a tab.

 

The following format is generally used:

 

• The first field in the krb.conf file denotes the realm name. By

 

convention, realm names are in upper-case letters to visually

 

distinguish them from domain names.

 

Realm names are case sensitive; you must type the correct case for

NOTE

 

the realm name if your site does not follow the upper-case

 

convention.

 

• The second field of the configuration file indicates the fully qualified

 

 

domain name (FQDN) of the host security server for that realm.

 

• The order of entries in the krb.conf file is important on the client

 

system as it is used to identify the intended order of redundant

 

Security Servers. Applications attempting to connect to the Security

 

Server, use this file to read the entries in the listed order. Redundant

 

security servers are used when higher priority security servers are

 

unavailable or a network time-out has occurred. For example, during

 

the authentication sequence when the network connection between

 

the client and a security server is interrupted.

 

To create comments, use the pound sign (#). Any characters after a

 

# symbol are ignored. Blank lines and any leading or trailing white

 

spaces in a line are also ignored.
