KRB5_SET_DEFAULT_REALM(3)				   BSD Library Functions Manual 				 KRB5_SET_DEFAULT_REALM(3)

NAME

     krb5_copy_host_realm, krb5_free_host_realm, krb5_get_default_realm, krb5_get_default_realms, krb5_get_host_realm, krb5_set_default_realm --
     default and host realm read and manipulation routines

LIBRARY

     Kerberos 5 Library (libkrb5, -lkrb5)

SYNOPSIS

     #include <krb5.h>

     krb5_error_code
     krb5_copy_host_realm(krb5_context context, const krb5_realm *from, krb5_realm **to);

     krb5_error_code
     krb5_free_host_realm(krb5_context context, krb5_realm *realmlist);

     krb5_error_code
     krb5_get_default_realm(krb5_context context, krb5_realm *realm);

     krb5_error_code
     krb5_get_default_realms(krb5_context context, krb5_realm **realm);

     krb5_error_code
     krb5_get_host_realm(krb5_context context, const char *host, krb5_realm **realms);

     krb5_error_code
     krb5_set_default_realm(krb5_context context, const char *realm);

DESCRIPTION

     krb5_copy_host_realm() copies the list of realms from from to to.	to should be freed by the caller using krb5_free_host_realm.

     krb5_free_host_realm() frees all memory allocated by realmlist.

     krb5_get_default_realm() returns the first default realm for this host.  The realm returned should be freed 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 freed with krb5_free_host_realm().

     krb5_get_host_realm() returns a NULL terminated list of realms for 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 host to form a realm.
     Caller must free realmlist with krb5_free_host_realm().

     krb5_set_default_realm() sets the default realm for the context.  If NULL is used as a 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.
