Since I linked our Microsoft Active Directory with my Apex application using LDAP, I am trying to retrieve the groups for the user currently logged in from the Active Directory.
Here's the documentation: https://docs.oracle.com/cd/E59726_01/doc.50/e39149/apex_ldap.htm#AEAPI242
Here's my code of my dynamic action on page load, I am trying to retrieve a VARCHAR2 of all the groups the current user is part of, and to put it in a display-only field :
BEGIN
:P1_NEW := APEX_LDAP.MEMBER_OF2(
p_username => v('APP_USER'),
p_pass => 'mypassword',
p_auth_base => 'DOMAIN\',
p_host => 'XX.X.XXX.XX',
p_port => 389);
END;
But when I load my page, this error occurs
Ajax call returned server error ORA-31202: DBMS_LDAP : Erreur client/serveur LDAP : Invalid credentials. 80090308: LdapErr: DSID-0C090439, comment: AcceptSecurityContext error, data 52e, v4563 for Execute PL/SQL Code.
What's wrong in my code ? Thank you in advance for your help.

I think you are using wrong the API Package APEX_LDAP. I am doing this on my own enviornment in a different way, but I am using Enterprise Edition:
I have an authentication schema to make the login against the LDAP server of my own company. That authentication schema replaces the default one of Apex Locally managed users.
Application --> Shared Components --> Authentication Schemas --> Custom
function fn_val_user_pwd_ldap (
p_username in varchar2,
p_password in varchar2
)
return boolean
is
l_ldap_host varchar2(100) := 'myldaphost.com';
l_ldap_port number := 389 ;
begin
if APEX_LDAP.AUTHENTICATE(
p_username =>p_username,
p_password =>p_password,
p_search_base => 'OU=Users,OU=Mycompany,DC=de,DC=com,DC=corp',
p_host => l_ldap_host,
p_port => l_ldap_port)
then
dbms_application_info.set_action(null);
return true;
else
apex_util.set_authentication_result(p_code => 110);
apex_util.set_custom_auth_status(p_status => 'Username or password incorrect.');
dbms_application_info.set_action(null);
return false;
end if;
end;
Then, I have a post auth procedure in the same authentication method to retrieve the groups in LDAP. I prefer this way because it executes after the authentication, but you can do it also with a dynamic action.
declare
l_groups varchar2(4000);
BEGIN
l_groups := APEX_LDAP.MEMBER_OF2(
p_username => ':APP_USER',
p_pass => 'mypassword',
p_auth_base => 'OU=Users,OU=Mycompany,DC=de,DC=com,DC=corp',
p_host => 'myldaphost.com',
p_port => 389);
htp.p('Is Member of:'||l_groups);
END;
We don't use SSL to communicate internally with the LDAP Server, as this application is intranet. So the parameter p_use_ssl
is by default to N.
As I was telling you in the comment section of your own question, I think the parameter p_auth_base refers to the LDIF format of your own LDAP server, not the domain name that refers to the AD.
UPDATE
Let me show you how it works. ( Of course, I hide sensitive information of my own company ). Sometimes it might happen that you can't get the group information as null. I am not sure here whether is a LDAP authorization issue rather than a problem with the APEX package itself
