KRB5_ANAME_TO_LOCAL... FreeBSD Library Functions Manual KRB5_ANAME_TO_LOCAL...
krb5_aname_to_localname -- converts a principal to a system local name.
Kerberos 5 Library (libkrb5, -lkrb5)
#include <krb5.h>
krb5_boolean
krb5_aname_to_localname(krb5_context context, krb5_const_principal name,
size_t lnsize, char *lname);
This function takes a principal name, verifies its 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 and error is returned.
If size (lnsize) of the local name (lname) is to small, an error is
returned.
krb5_aname_to_localname() should only be use by application that implements
protocols that doesn't transport the login name and thus needs to
convert a principal to a local name.
Protocols should be designed so that the it autheticates using Kerberos,
send over the login name and then verifies in the principal that 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().
