I want to query LDAP server via Pl/Sql code. I am able to connect to the LDAP server but having difficulty to search/retrieve LDAP attributes.

Attached is the code.

If I call the function with a valid input value for LDAP attribute "uid" it returns 1. Otherwise 0. When it returns 1 I want to search LDAP to get the value of the LDAP attribute "cn" corresponding to the input "uid" attribute.

How can I write the code?
CREATE OR REPLACE PACKAGE BODY TEST IS
 FUNCTION test (in_uid IN VARCHAR2) RETURN NUMBER AS
 retval           INTEGER;
 my_attr      VARCHAR2(256);
 my_str       VARCHAR2(256);
 my_session   DBMS_LDAP.session;
 my_attrs     DBMS_LDAP.string_collection;
 my_message   DBMS_LDAP.message;
 entry_index      PLS_INTEGER;
 ldap_host        VARCHAR2(256);
 ldap_port        VARCHAR2(256);
 ldap_user        VARCHAR2(256);
 ldap_passwd      VARCHAR2(256);
 ldap_base        VARCHAR2(256);

 BEGIN
 retval := -1;
 ldap_host  := 'server.myco.com';
 ldap_port  := '389';
 ldap_user  := '';
 ldap_passwd:= '';
 ldap_base  := 'ou=People, ou=Intranet, dc=XXX, dc=com';
 my_session := DBMS_LDAP.init(ldap_host, ldap_port);
 retval := DBMS_LDAP.simple_bind_s(my_session, '', '');
 my_attrs(1) := '*';
 my_attr := 'UID';
 my_str  := my_attr || '=' || TRIM(in_uid);
 retval := DBMS_LDAP.my_s(my_session, ldap_base, DBMS_LDAP.SCOPE_SUBTREE, my_str, my_attrs, 0, my_message);
 retval := DBMS_LDAP.count_entries(my_session, my_message);
 RETURN(retval);
 END;
END;

retval := DBMS_LDAP.my_s(my_session, ldap_base, DBMS_LDAP.SCOPE_SUBTREE, my_str, my_attrs, 0, my_message);

-- the above value will be overwritten with --
retval := DBMS_LDAP.count_entries(my_session, my_message);
