Application Express :: LDAP Authentication Using Embedded Weblogic Server
Sep 28, 2012
I am trying to use embedded weblogic server for creating an LDAP authtication secheme but it is not working
I believe that embedded ldap server works on the same port as the admin server of the domain but configuring it has been a pain. I got the following code from forum to test the ldap connection
declare
l_retval pls_integer;
l_retval2 pls_integer;
l_session dbms_ldap.session;
l_ldap_host varchar2(256);
[code]........
Every time I run this, I get the following error
ldap session : 01000000(returned from init)
error: ORA-31202: DBMS_LDAP: LDAP client/server error: Invalid credentials
-31202

I have got single sign on working via the built in LDAP Directory authentication in APEX. But at the moment this is letting everyone who is within AD log inHow can I assign role permissions to each logged in user so some users have an admin role and see certain parts of the application / pages / navigation items while editors and readers have different permissions
And also to restrict access to certain pages within the application

We like to integrate the window LDAP to a new oracle database for user authentication. For example, this is a new test database and we don't have any users created.Now we like to figure out if we created the users with same id as in LDAP userid, how they can be authenticated externally by LDAP. I read and heard some info on OID provided by oracle but need some more step by step info to experiment.

I'd like to have my 11g database authenticate users against an OpenLDAP service. We'd still create accounts in the database, and do authorization within the database, but I'd just want to the user's passwords authenticated externally, against the OpenLDAP service. Is this possible? My searching through these forums and Google seems to indicate that you can do it if you run an Oracle Internet Directory (OID) service. I do not want to have to install and maintain an Oracle Internet Directory service. I'd like to do it without it.
I have a working PL/SQL function (below) that can authenticate a passed in username & password against our OpenLDAP directory. Is there any way for me to have Oracle call this function for the database user authentication? Or is there any other way for me to get the Oracle database to directly authenticate against OpenLDAP without having to run OID?
create or replace function ldap_authenticate(username varchar2, password varchar2)
return boolean is
begin
begin
if dbms_ldap.success = dbms_ldap.simple_bind_s(

I need to enable authentication over LDAP SSL. I've configured a wallet (auto login) containing required certificates and set accordingly WALLET_PATH and WALLET_PWD settings using apex_instance_admin.set_parameter method. With this, everything is working fine and LDAP over SSL is working well. It confirms that the wallet is properly configured, valid and usable.
So, the wallet was created with auto login option and it seems to work well without specifying password when calling utl_http.
Proof of properly configured auto login wallet (without password).
TEST01@DB11G> exec show_html_from_url('https://www.verisign.com/'); -- test without wallet
BEGIN show_html_from_url('https://www.verisign.com/'); END;
*
ERROR at line 1:
ORA-29273: HTTP request failed
ORA-06512: at "SYS.UTL_HTTP", line 1527
ORA-29261: bad argument

PL/SQL procedure successfully completed.
TEST01@DB11G> exec show_html_from_url('https://www.verisign.com/'); -- It works!
PL/SQL procedure successfully completed. So, when I configure WALLET_PATH without WALLET_PWD, it not seems to work as it should with my auto login wallet...
Is it APEX not handling auto login wallets correctly?

What are the pro's and con's to using the APEX Listener vs the Embedded PL/SQL gateway?
We just started using APEX and on a development server, we set it up using the EPG because this seemed like the easier thing to do. However, they now have a couple apps that are approaching production status and I now need to look at placing the APEX runtime on our production Oracle Database server. So I am trying to decide if I should continue using the EPG or if I should use the APEX Listener.
The server is Windows Server 2008 Enterprise R2 (64 Bit) with Oracle 11g R2 (11.2.0.3.0) also running at 64 bit. I am planning on using APEX 4.2.1.
I have also not found information about how to move APEX application from development to production. Do I export the schema from the dev server and import it to the production server? Do I have to recreate the same workspace name on the production server as well?
use a separate dev and production server setup for APEX?

We just did an upgrade to 4.2 on a new WebLogic server. We are using the latest Apex Listener as well.The install seemed to go well (no errors during the DBA install) and we configured the Listener to connect to the database using the basic connection settings.I was able to login to the Admin console and create my workspace and users, but I cannot even get the workspace login screen to appear.All we get it is:
Error Error processing request.
ORA-01403: no data found
This is the only thing that shows up when going to the default Apex URL....

I got a database query which takes about 4-5 sec to run, but since it seems to take too long time something happens, timeout(?) and returns a white page.
What would be the proper way to debug this? I only got access to the web console. Sometimes on the second try it loads the webpage, and I guess it has cached it then and can load it. So maybe weblogic timesout my request?

We just upgraded from Application Express 4.0.2.00.07 to Application Express 4.2.2.00.11. We are using one common application to authenticate and redirect to other applications.
We use the following code:
wwv_flow_custom_auth_std.login( P_UNAME => :P101_USERNAME, P_PASSWORD => :P101_PASSWORD, P_SESSION_ID => v('APP_SESSION'), P_FLOW_PAGE => '2000:1' );
We start to get the following authentication error after the upgrade. There is no authentication configured for this application.
ORA-1403: no data found This is the same code we used from htmldb 2.x through Apex 4.0.2.00.07.

We are close to successfully getting our CAS authentication integrated with Apex Listener 2.0 and Apex 4.2.1. We are using Weblogic app server for the Listener configurations and have been able to get the remote_user passed to Apex after login to CAS. We just set the header variable in the new 'HTTP Header Variable' authentication scheme. However there is a glitch at the callback from CAS -- we get the error 'wong number of types of arguments in call' and the URL shows: ..... /apex/apex_authentication.callback.
I see the documentation about this CALLBACK procedure, but am not sure how to set it to go back to the application. I know that CAS is working and passing the userid to the application because I can manually type in the app URL .... /apex/f?p=xxx and I immediately get into the application and the correct userid is identified --whereas initially when I hit the same application it sends me to our Central CAS server for login.
where the parameters of this procedure need to be set and how to set them. I assume the procedure needs to be called by Weblogic?for the callback to find the original calling application so it doesn't have to be 'hard-coded'. I see that one of the parameters is 'p_app_id'. I think our Weblogic engineer was assuming the call to that procedure would 'take care' of the return to the original calling application but obviously we have missed some configuration.

I do not see an option in web sheets to use HTTP Header values for authentication. Any workaround in order to use OAM for authentication to web sheets?

Our apex currently has LDAP authentication scheme. We have many applications within the workspace. We are looking for a way to have one authentication scheme defined for all the applications so that user doesn't have to enter username/password for each application. How can I share my LDAP authentication scheme for multiple applications.

OS authentication is not working
Does 11g need any different setting?
Following are the settings
1)
SQL> show parameter os_a
NAME TYPE VALUE
------------------------------------ ----------- --------------
os_authent_prefix string OPS$
remote_os_authent boolean FALSE
2) sqlnet.ora has following setting
SQLNET.AUTHENTICATION_SERVICES = (NTS)
3) I have created user like following
sql> create user OPS$CLASS
2 identified externally
3 default tablespace user_data
4 temporary tablespace temporary_data
5 profile clas_prof
6 account unlock;
user created.
sql> grant connect to OPS$CLASS;
Grant succeeded.
With the same settings it successfully connects from my 9i client to the 9i database

I have oracle database server set with Windows NT authentication. How can I get rid of this kind of authentication as this is holding up additional Windows Domain with its own PDS and so on. Or is it possible to move Oracle Database server to a different Domain and authentication to be coming from new domain?

I have the following tables: First one (PART) is the master and other 2 are children.I need to create query that would link both children to the parent. So I was thinking about using embedded refcursor (since my function returns a ref cursor).
on using this ? Is this ok or any other better way of doing this ?
TABLE PART
PART_ID, PART_NAME
TABLE ABC
ABC_ID,PART_ID

I'm trying to migrate an Apex Application from one server to a newer server . My custom app I used the theme from Go Live CheckList samples....
Well, when trying to install that application I get 'Insufficient space to install application ' with a BIG red X... I was able to install other Package Application except for the one I need and now my application errors out because of some shared Themes. At first I thought it was a DB thing so I downgraded back to 10g from 11....but that didn't work... Apex works fine...
Other samples work fine...Version Apex 4.2.2 and Oracle XE 10g...

I am trying to run an Oracle report with a query that has an embeded sql. this sql is returning more than 1 row, and the report is failing.
I need to pick the latest record entered that this sql return.
I tried rownnum and it works but only i can get the rown num I specify, not the latest record. I try to order, but I am getting an error back.
select w.emp_no, (select t.timestamp
from tob.work_unit t
where t.work_date = to_date('20130312', 'YYYYMMDD')
and rownum = 1
order by t.timestamp desc)
,w. spare_type
from work.work_unit w
where w.work_date = to_date('20130312', 'YYYYMMDD')
I am getting missing right parenthesis at the order by keyword My report is much complex than this, but I am tring to see if I can get the row that I want.

I've been examining som old queries in an existing db due to more and more problems regarding performance. The sql is used as backend for a java/jboss web application with the possibility for users to enter data. With more and more data, there starting to come complaints about the performance.
I stumbled upon a select query with an embedded cursor similar to this :
select id, name ...,
cursor(select id, sequence.... from table2),
cursor(select id, name.... from table3)
from table1
join table4 on (table1.id = table4.id)
where .....
The javacode is a prepared statement with the actual sql as a string and the content of the cursors saved in conjunction with each row.
when i use sqldeveloper to show the explain plan without the cursors, the cost is 2428
when i use sqldeveloper to show the explain plan with just 1 of the cursors, the cost is ~165000
Is there a better way to do this instead of cursors ?

after my first Apex installation I have got the above mentioned error. I have tried the following Apex calls:
localhost:7778/apex
localhost:7778/apex/apex_admin
Instead of using localhost I used the hostname or the IP address of the box without success.The whole installation process went fine from scratch. No errors, no warnings, nothing.I am using the following environment:
CentOS 6.3
Oracle 11.2.0.3 EE
Apex 4.1.1
With exec dbms_xdb.sethttpport(7778); I enabled the above port number. If I look at the output of the lsnrctl status I see that my local listener is also listening on 7778. I have no errors in the alert.log and no other trace files where I can have a look at.
