4.0.1 to 4.1.1 -- LDAP Directory Authentication Scheme fails

Question

Using the out of the box LDAP directory authentication scheme that worked fine in v. 4.0.1 is failing in v. 4.1.1. User authentication is failing with 'Invalid Login Credentials'. Debug shows that the User is 'nobody'. Looking at v. 4.0.1, User shows 'Admin'. Also, the 'LDAP test link' is no longer available in 4.1.1 - that's a bummer.
Example debug 4.1.1:
4161     426774014496602     nobody     103     101     50     6 minutes ago     0.8562
Example debug 4.0.1:
661     3340172823117775     ADMIN     130     101     57     36 seconds ago     0.3298
Does anyone know if something was changed with the standard LDAP directory scheme? Or am I missing some configuration?

Hi Julie,
sorry, there is too little context for me to answer this question. I have no idea where and how you got that debug output, for example.
As for testing, the LDAP authentication scheme calls wwv_flow_custom_auth_ldap.authenticate. It's no official API and we may revoke the grant in future versions, but in 4.1, you can for test LDAP auth in SQL workshop with
declare
    l_status boolean;
begin
    l_status := wwv_flow_custom_auth_ldap.authenticate (
                                 p_ldap_host     => ...host...,
                                 p_ldap_port     => ...port...,
                                 p_dn            => ...dn_string...,
                                 p_search_filter => ...search_filter...,
                                 p_password      => ...password...,
                                 p_use_ssl       => ...ssl_mode... (Y for SSL, A for SSL with authentication, N for no SSL),
                                 p_use_exact_dn  => ...use_exact_dn... (Y or N) );
    dbms_output.put_line(case when l_status then 'authenticated' else 'auth error' end);
end;Regards,
