Application Express :: LDAP Authentication Working But How To Add Roles And Rules
Jan 22, 2013
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

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

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

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?

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.

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.

We have upgraded our apex installation from APEX 4.0.2 to 4.2.2 and APEX listener to 2.0.2
Below is our configuration
Host 1 : Oracle databaseOracle database - 10.2.0.5APEX - 1.1.3
Host 2 : Apex listener on Weblogic serverWeblogic server - 10.3.5 APEX listener - 2.0.2
Post the upgrade , applications that were existing before the upgrade are not working properly.
Errors faced:1.When we edit any page in application - we get no data found error2.
When we run any application - We get no data found error We are able to create new applications without any issues.Luckily , we had the export backup of one application taken before upgrade. We imported that back( only one application ) and that application is working fine. We imported the application in apex.oracle.com as well and get the same error[URL]... occurs during page 'Edit' as well.

I have an application built in Apex 4.2It's been running fine for several weeksI've not made any changes to the codeSuddenly it developed what seems to be a cache problem.If I enter a search criteria; it displays results. I enter a different search criteria and it brings back the same results as the first criteria.I enter a search criteria in a different field and I still get the results from the first searchI go from Internet Explorer to Mozilla.
DIfferent search criteria, but same issue. Google chrome - same issueThe obvious answer is to clear the cache.I have a process set up that is clear Cache for Items , on submit after computations and validations and then I list all the items individually.This process has been there all along.
I never had this problem before.If I log out and come back in, same issue. What ever I enter as the first search criteria is the results no matter how I search

Email no longer working for users after upgrading from 4.0 to 4.1. New 'principal' APEX_040100 added to same ACL as previous version's principal APEX_040000. In fact, both still exist in ACL.
Error code in APEX Admin Mail Queue: ORA-24247: network access denied by access control list (ACL)
What could be causing the email facility within APEX to no longer work?

I have an application where I use the zero session ID for public users. The problem is, I have a region that contains a report linking to PDF files contained in a BLOB and I use GET_BLOB_FILE_SRC to link to the PDFs. I've included the report in my global content (page 0) and want it to be available to all visitors. The problem is, it only works when a user has authenticated. It throws a PAGE NOT FOUND error for public users.

I have enabled SSO for my application. It was working in 4.1 version. I have upgraded to 4.2 now and the same code doesn't work now.I have created an authentication scheme where i check if a particular person is an employee based on a flag. If he is, then I return 1 to the authorization scheme i have created. This always returns 0 even if the flag is set to 'Y'. I have tried hard coding the user_id as well. It doesn't work.
I tried printing the :APP_USER but it does not give any output.

I have a Select list which when null should disable a button and when not null should enable it. For which I tried the Advanced DA. Strangely, in the final page where we select the item that is going to be controlled, the button is not listed! I can see other display items etc which I can select but not the button.

I am running my oracle apex application on 4.2.2 on apex.oracle.com. Exporting the application seems to work but when I go to import the application as a copy the regions within a particular page are not working correctly. I want to be able to export the application and import a new copy as a DEV/TEST application and have it function the same way. On the original application the region will display to the right when hovered over the edit button but in the new one it will go to the left and not format correctly.How I would like it is just for the copy application to perform the same way the original copy does. I selected to install all dependent objects and don't know what steps I have missed to have the regions not working like they do on the original application. related to CSS not exporting/importing correctly?

APEX 4.1 / 11g
Theme 21
I have a page with about 8 Classic reports. 4 of them percentage values, 4 totals. I have one RG with a Percentage or total option. When I select the percentage radio, it should hide all the total regions. When I select the totals radio it should hide all the percentage regions. Simple? So I thought. This is what I did.
1. Created a RG(P2_RG) -> Page value is redirect and set value.
2. STATIC:Percentage;P,Total;T
In the RG, I have created a normal DA which has the true and false events as follows.
Event -> Change
Items -> P2_RG
equal to -> P
In the true actions, I have hidden the 4 totals regions.
shown the 4 Percent regions.
In the false action, I have shown
hidden the 4 percent region
shown the 4 totals region.
The event specification for one these true actions is
Action -> Hide (If I am hiding)
Fire when event is ->True
Selection type -> region
Region -> The region I want to hide/show.
But it does not work! I tried to replicate the issue on apex, by using a small example but could not. Works fine in apex following the same process.
[URL]
I tried to debug by having a display item to show the value when I change the radio button. The values are changing properly. I tried actually, adding a condition filter in the region itself by using the "Value of item/column in expression1 = expression 2" where expression one I tried :P2_RG and expression 2 as P but that just hides the whole region.

I have some Javascript in an Apex page, running in 'Execute when page loads'. It does some stuff to a results grid. It works fine on page load, but then doesn't run when I page through, or sort the grid. I presume this is because the grid is being sorted / paged using Ajax, which means the page isn't being fully loaded. Is there anywhere else I can put the code so it gets applied to the grid on sorts and paging?
