DESCRIPTION

krb5_free_host_realm ();
frees all memory allocated by Fa realmlist .

krb5_get_default_realm ();
returns the first default realm for this host. The realm returned should be free with free (.);

krb5_get_default_realms ();
returns a NULL terminated list of default realms for this context. Realms returned by krb5_get_default_realms ();
should be free with krb5_free_host_realm (.);

krb5_get_host_realm ();
returns a NULL terminated list of realms for Fa host by looking up the information in the [domain_realm] in krb5.conf or in DNS If the mapping in [domain_realm] results in the string dns_locate DNS is used to lookup the realm.

When using DNS to a resolve the domain for the host a.b.c, krb5_get_host_realm ();
looks for a TXT resource record named _kerberos.a.b.c and if not found, it strips off the first component and tries a again (_kerberos.b.c) until it reaches the root.

If there is no configuration or DNS information found, krb5_get_host_realm ();
assumes it can use the domain part of the Fa host to form a realm.

krb5_set_default_realm ();
sets the default realm for the Fa context . If NULL is used as a Fa realm , the [libdefaults]default_realm stanza in krb5.conf is used. If there is no such stanza in the configuration file, the krb5_get_host_realm ();
function is used to form a default realm.
