username case conversion wrapper. It is now (very) explicit where we are
mapping between an incoming Windows username, and when we are doing a
UNIX password entry lookup, which may change the case of the given
username.
This makes things *much* clearer (IMHO:-) and will ease the adding of
the 'groupname map' parameter, and the addition of the special 'jeremy'
mode for Samba where unix users will not be needed. (We must think of
a better name for it :-).
Jeremy.
