Error in Custom Ldap Authentication

Question

Hi All,
I was trying to use the custom LDAP authentication( [Earlier Post|http://forums.oracle.com/forums/thread.jspa?threadID=2251976&stqc=true] ) but was not successful in making it work with our AD LDAP server. Thats when I came across post [ http://forums.oracle.com/forums/thread.jspa?messageID=916185&#916185|http://forums.oracle.com/forums/thread.jspa?messageID=916185&#916185]
I used the same function
create or replace function authenticate_aduser(
p_username in varchar2,
p_password in varchar2)
return boolean
is
l_user varchar2(256);
l_ldap_server varchar2(256) := '<Hostname>';
l_domain varchar2(256) := '<Domain Name>';
l_ldap_port number := 389;
l_retval pls_integer;
l_session dbms_ldap.session;
l_cnt number;
begin
l_user := p_username||'@'||l_domain;
l_session := dbms_ldap.init( l_ldap_server, l_ldap_port ); -- start session
l_retval := dbms_ldap.simple_bind_s( l_session, l_user, p_password ); -- auth as user
l_retval := dbms_ldap.unbind_s( l_session ); -- unbind
return true;
exception when others then
l_retval := dbms_ldap.unbind_s( l_session );
return false;
end;Test it by giving correct password
     SQL> declare
begin
if authenticate_aduser('<username>','<correct password>') then
dbms_output.put_line('Test Successful');
else
dbms_output.put_line('Test Failed');
end if;
end; 2 3 4 5 6 7 8
9 /
Test Successful
PL/SQL procedure successfully completed.Tested it by giving wrong password
SQL> declare
begin
if authenticate_aduser('<user name>','<wrong password>') then
dbms_output.put_line('Test Successful');
else
dbms_output.put_line('Test Failed');
end if;
end; 2 3 4 5 6 7 8
9 /
Test Failed
PL/SQL procedure successfully completed.So the fundtion is working perfectly with LDAP server.
I am trying to create a custom authentication scheme with the above function.
Shared Components -> Authentication Schemes -> create ->From Scratch ->
In Autentication Function -> return authenticate_aduser(:P101_USERNAME,:P101_PASSWORD);
In Logout URL -> wwv_flow_custom_auth_std.logout?p_this_flow=&APP_ID.&amp;p_next_flow_page_sess=4155:PUBLIC_PAGE
Then after setting this as the current authentication scheme. Whenever I try to login with correct credentials it is giving me error
Invalid Login Credentials
Kindly let me know were I am going wrong here.

Answer 1

I was able to fix this.
I used the same function authenticate_aduser
and then followed blog http://www.talkapex.com/2009/03/custom-authentication-status.html to create a custom authentication. It worked finally.
Thanks to Martin for his wonderful post.
