Name

krb_get_lrealm − Host/realm identification routines. 

Syntax

 #include <krb.h>
 #include <des.h>

 krb_get_lrealm (realm, n)
 char *realm;
 int  n;

 char *krb_get_phost (alias)
 char *alias;

Arguments

alias Identifies a host whose name is to be converted to an instance name.  The alias string is overwritten with the instance name.  The alias string must be stored in a buffer of at least INST_SZ characters. 

realm Identifies a specific realm. 

n Specifies a specific position in a series of Kerberos hosts; must be set to 0. 

Description

The routines of krb_get_lrealm allow an application to obtain information on host/realm relationships in a Kerberos network.  The routines of this library are:

krb_get_phost
Converts the hostname pointed to by alias, which can be either an official name or an alias, into the instance name to be used in obtaining Kerberos tickets. 

krb_get_lrealm
Initializes realm with the nth realm of the local host. The argument realm should be large enough to contain the maximum realm name determined by the constant REALM_SZ.  The local realm name is stored in the /etc/krb.conf file.  See the krb.conf(5krb) reference page.
