Instantiate a new current user object,
loading the user by paramhash:
my $item = Jifty::Plugin::AuthLDAPOnly::Model::Item->new( Jifty::Plugin::AuthCASOnly::CurrentUser->new(email => 'user@LDAP.user'));
if you give the param _bootstrap => 1
your object will be marked as a bootstrap user. You can use that to do an endrun around acls.
