NAME¶
krb5_aname_to_localname —
converts a
principal to a system local name
LIBRARY¶
Kerberos 5 Library (libkrb5, -lkrb5)
SYNOPSIS¶
#include <krb5.h>
krb5_boolean
krb5_aname_to_localname(
krb5_context
context,
krb5_const_principal name,
size_t lnsize,
char *lname);
DESCRIPTION¶
This function takes a principal
name, verifies that it is
in the local realm (using
krb5_get_default_realms()) and
then returns the local name of the principal.
If
name isn't in one of the local realms an error is
returned.
If the size (
lnsize) of the local name
(
lname) is too small, an error is returned.
krb5_aname_to_localname() should only be use by an application
that implements protocols that don't transport the login name and thus needs
to convert a principal to a local name.
Protocols should be designed so that they authenticate using Kerberos, send over
the login name and then verify the principal that is authenticated is allowed
to login and the login name. A way to check if a user is allowed to login is
using the function
krb5_kuserok().
