krb5_aname_to_localname

KRB5_ANAME_TO_LOCALNAME(3)				   BSD Library Functions Manual 				KRB5_ANAME_TO_LOCALNAME(3)

NAME

     krb5_aname_to_localname -- converts a principal to a system local name

LIBRARY

     Kerberos 5 Library (libkrb5, -lkrb5)

SYNOPSIS

     #include <krb5/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 authen-
     ticated 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().
