DDEESSCCRRIIPPTTIIOONN
This function takes a principal _n_a_m_e, verifies that it is in the local
realm (using kkrrbb55__ggeett__ddeeffaauulltt__rreeaallmmss()) and then returns the local name
of the principal.
If _n_a_m_e isn't in one of the local realms an error is returned.
If the size (_l_n_s_i_z_e) of the local name (_l_n_a_m_e) is too small, an error is
returned.
kkrrbb55__aannaammee__ttoo__llooccaallnnaammee() 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 authenti-
cated is allowed to login and the login name. A way to check if a user
is allowed to login is using the function kkrrbb55__kkuusseerrookk().
