Restart Admin Login Credentials in Apex 4.0 & Oracle 11gr2

Hi all,
We face a major issue. We are unable to connect our admin account for some unknown reason. We keep receiving the following message "Invalid Login Credentials". We tried to change the admin credentials with sqlplus.
We tried the usual procedure "apxchpwd" successfully, but we still cannot log in.
We then tried to create a new admin2 account with the following pl/sql block.
SQL> connect APEX_030200 as sysdba
Enter password:
Connected.
SQL> begin
2 wwv_flow_api.set_security_group_id(p_security_group_id=>10);
3 wwv_flow_fnd_user_api.create_fnd_user(
4 p_user_name => 'admin2',
5 p_email_address => '[email protected]',
6 p_web_password => 'admin2') ;
7 end;
8 .
SQL> /
PL/SQL procedure successfully completed.
SQL> commit
2
SQL> commit;
Commit complete.
SQL> alter user APEX_030200 account lock;
User altered.
SQL> quit
We cannot connect with either admin & admin2.
Any good idea?
Roger

Hi,
I'm not expert on this area, sorry.
I would check what like FLOW% and APEX% users there is in database.
Also query DBA_REGISTRY what is current/valid APEX version.
Then try again with correct APEX versions scripts reset ADMIN password.

  • OBIEE 11.1.1.6 SampleApp207: APEX Admin login issue

    Hello,
    I have successfully started the virtual image and all it's associated services.
    As mentioned in the Login Credentials sec. 3.2 of the deployment guide, the APEX credentials of admin/Welcome1# does not work.
    I tried using the apxchpwd.sql to change the admin password but although the script says it completed successfully, I still cannot login with the new password.
    Any idea how to login to APEX on this virtual image?
    Thanks,
    Manish

    edit the apxchpwd.sql
    its probably the wrong apex version, mine was..
    change it to APEX_040000 (you can connect to the database to verify the schema name, if it still doesnt work)
    then run it and it will reset the password..

  • Invalid Login Credentials  after a brand new install of APEX 2.2

    I'm trying to install APEX2.2 for the first time to see what it can do.
    I have followed the install document.
    When I got ot here, http://localhost:7777/pls/htmldb
    It requests a workspace, username, password.
    back to the documentation, it states use http://localhost:7777/pls/htmldb/apex_admin
    to create your workspace. And to sign in as admin, and the password passed into @apexins.sql When I try that, it results in the error message "Invalid Login Credentials" The documentation does not describe anything about that!
    Please help
    Thanks,
    Jason

    Joel,
    I had a cut and paste error in my last posting, I actually ran this:
    alter user FLOWS_020200 account unlock;
    connect FLOWS_020200/apex
    begin
    wwv_flow_api.set_security_group_id(p_security_group_id=>10);
    wwv_flow_fnd_user_api.create_fnd_user(
    p_user_name => 'admin2',
    p_email_address => '[email protected]',
    p_web_password => 'admin2') ;
    end;
    alter user FLOWS_020200 account unlock;
    I have a thought on why Ben and I both had this same "Invalid Login Credentials" issue. In my case it certainly wasn't because of any special characters in the password. I used apex as a password.
    From reading Ben's post I see we both first had a problem with the images directory. Sounds like Ben had the same issue I had. Which was in the marvel.conf I first entered this
    Alias /i/ "C:\oracle\product\10.2.0\db_as\Apache\Apache\images"
    instead of this:
    Alias /i/ "C:\oracle\product\10.2.0\db_as\Apache\Apache\images/"
    This caused my http://localhost:7777/pls/htmldb URL to paritially work. I'm thinking that may be what caused the "Invalid Login Credentials" once I made the Alias adjustment.
    Thanks,
    Jason

  • Authentication - "Invalid Login Credentials" ? ? ?

    Hey guys,
    Need some help regarding Log in.
    I have a table in the database (table name USER_SECURITY) which has the list of users who are authorized to log in to the application.
    I have to incorporate this in the application page
    Could you please help me with the logic how to go about it in APEX
    Thank You for your help and suggestions

    Hi,
    I did try the link and it helped me understand alot, [ http://djmein.blogspot.com/2007/07/custom-authentication-authorisation.html]
    and I tried an example as mentioned in Duncan Mein's Blog and it did work, but then when I try to use it in my application and entered the username and password it says *"Invalid Login Credentials".*
    Here's the code I used:
    The table was already created in the database: ASQ_USER_SECURITY

    Switch on your Custom Scheme: made it “My Auth Scheme”
    Also Altered the Login Process on Page 101

  • Invalid login credentials when install oracle xe

    Hi friends,

  • Batch schedule won't allow me to enter "login credentials"

    Hello All,
    A most random thing happened today. I am on version 11.1.2.3.500 of EPM and was in the process of creating a Batch (for test) and after doing this successfully a number of times (10+), I deleted the batch I had created attempting to create a new one. However, this time, the database connection has come up blank as can be seen below.
    The 2 fileds highlighted below were originally editable, and the userid was filled in with "admin". I would normally just enter the password and proceed, however in this case, I can't write anything into either of the 2 fields highlighted below.
    This naturally creates a problem as I can not now see the dimensions from the reporting database - so can not select any dimensions!
    I've powered down the virtual machine, restarted my services (2x) and everything else looks and works fine except for this issue.
    Any ideas?
    Regards
    Dermott

    Thanks for the reply LRBS. I did spend some time going through the logs but they turned up empty and here's why...
    It turns out it was a corrupted BATCH. Somehow, each time I created a new "Batch Schedule" and used my original batch as a reference it made it impossible to edit/enter the correct login credentials for the server element.
    Hopefully this helps someone else in the future.
    Action: "Delete and recreate your Batch if you get this error."

  • Invalid login credentials after upgrading to 3.0.1

    I have upgraded our apex2.1 version to 3.0.1. When trying to login for the first time I entered my database user name in the workspace field and enter my database user name and password as per upgrade instructions. However, all I get is the error 'Invalid login credentials'. The upgrade instructions do not mention any additionals action steps that must be taken. Can anyone please advise how to solve this problem.
    Thanks, Richard

    I had the same problem and tried about everything with no success, until ...
    I changed the ADMIN password using the apxxepwd.sql script (can be found in the root of the 3.0.1 apex directory). Run this script under sqlplus as "sys/password as sysdba" and enter twice the ADMIN password when prompted for '&1'. Login on http://localhost:8080/apex/apex_admin, you'll be prompted to change the password. Change the password (may be the same as the old one) and now you can finally login as ADMIN.
    I did this on APEX 3.0.1 on a Oracle EXPRESS 10.2.0.1.0 on Windows Vista, and suppose this must work on other platforms too.

  • Pop of Admin login page

    I have created a page where I have buttons like delete and create report buttons. I am able to delete or add row in report(on same page), but whenever I click on delete or Add button, application ask for Admin username and password. Afte giving username/password, operation gets successful. But I dont want this login page to pop after clicking delete or add button.
    I have not written any process which ask application for this pop up. Infact i dont have any idea why pop up is coming.
    To tackle this problem,I tried entering following in OPTIONAL URL REDIRECT in Delete button.
    javascript:confirmDelete(htmldb_delete_message,'DELETE');
    But after that delete button became inactive. I am not able to understand, what is going wrong here:-(
    Please help me to get rid of Admin login Pop up.
    Thanks in advance!!!

  • Blank admin login box?

    Has anyone seen this before? My wife's MacBook Pro has been doing this for some months now. It prompts her login credentials when something is changed in system preferences or like this one, an update from Adobe. thank you!

    Back up all data before proceeding.
    Launch the Font Book application and validate all fonts. You must select the fonts in order to validate them. See the built-in help and this support article for instructions. If Font Book finds any issues, resolve them.
    Start up in safe mode to rebuild the font caches. Restart as usual and test.
    Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a software RAID, you can’t start in safe mode. In that case, ask for instructions.
    If you still have problems, then from the Font Book menu bar, select
              File ▹ Restore Standard Fonts...
    You'll be prompted to confirm, and then to enter your administrator login password.
    Also note that if you deactivate or remove any built-in fonts, for instance by using a third-party font manager, the system may become unstable.

  • Admin Login Gone, Guest Acct Only...

    I did a healthy search on my little problem here and mine appears to be a little different from the rest.
    I have my MacBook pro (Running the latest ver. of Tiger) set so that i need to authenticate my login and pass every time I open up the laptop or I deactivate the screensaver.
    Today, I opened'er up and for some reason my login and password didn't work. I thought that was weird and I rebooted (Ctrl-Opt-Power Button). Low and behold my Admin Login was gone! I only have access to this Guest Account that I created a while back.
    So, I login to the Guest Account and check out the Accounts Panel in System Preferences and nothing comes up. I click the button and the window hangs ("Loading Accounts" appears at the top, but nothing happens). I click 'Show All' to return to all the icons and then click Accounts and the window renders, but it's completely blank.
    *I did a lot of searching and I found the single-user-mode-using-NetInfo-Manager solution* and that didn't do anything. After I do the +"nicl -raw..."+ command, nothing seems to happen. While I was in Single User Mode, in the shell, I checked out my Users folder and my Account is still there.
    So, bottom line, I only have access to an unprivileged Guest Account and OS X can't seem to boot so I can see my Admin Account. I would much rather not reinstall OS X since I have a lot of graphic design, music and a lot of my photography work in that account.

    So what are we looking for with these "nicl" commands? I take it that the above is probably bad news somehow.
    nicl is the "NetInfo Command Line" interface. I wanted to see why you were getting the "ni_listprops: No such directory" message, and it is telling me that although the /users part of the NetInfo hierarchy exists, it seems to have lost the entries for your two real users.
    We could put them back, tediously, using nicl, but who knows what other "users" are missing. So your best bet is to restore the NetInfo Database. Funnily enough I just posted how to do this for another user. You might want to read Mac OS X, Mac OS X Server: How to Replace the NetInfo Database to help understand the instructions that follow (this is a more-or-less standard post I keep for this situation). Note you've already got your list of UIDs versus Users: 501 is Ghostmeat, and 502 is Guest.
    Your NetInfo database is corrupt. so we will need to give you a new one. This involves re-creating the user accounts, and the order in which they are created matters. I recommend you print this out in a largish mono-spaced font so you don't miss any spaces (or add extra ones). Note that case is important.
    Start up in Single User Mode and type carefully, with a return at the end of each line:/sbin/fsck -y
    Repeat the above until it says your disk is OK. Then:
    /sbin/mount -uw /
    cd /var/db/netinfo
    mv local.nidb/ local.nidb.bad
    rm /var/db/.AppleSetupDone
    ls -ln /UsersThis last command will give you one line for each user, plus one for the "Shared" directory, which doesn't interest us. Each user will have a line like one of these:
    <pre>drwxr-xr-x 29 501 501 986 Jan 17 18:38 michaelc
    drwxr-xr-x 14 520 20 476 Sep 10 2004 jdoe</pre>The second numeric field (501, 520) is the user ID (UID) and you need to list the uids against the shortname s given in the final column. Make sure you get the name right for UID 501! Then continue with
    rebootWhen you restart, you should get the Setup Assistant, just as if it was a new machine. You will be prompted for all of your user information. Be careful to use the same short name as previously for user 501.
    If there are any further users, these can be added, in the order of their UIDs, i.e. 502, 503 …, using System Preferences > Accounts. Again, be careful to use the same shortname. If there are any gaps in the UID sequence 501, 502, … you will need to create dummy users to fill them. These can later be deleted.
    Post back if you need further help, and to let us know how you get on!

  • Cannot change password or admin login

    i have done everything i was advised to do but it just cant work bcus has tied the password and admin login
    some were in the computer.some people advised that i should take it to an apple store in my country
    but we dont have an apple store or a representative in cameroun, what next do i do?pls help

    Hello:
    Ok here we go:
    1- You have to restart your MBA holding down the Command+S keys, and this will take you into Single User Mode and it’s Terminal interface.
    2- Then you have to check the filesystem. to do this you have to type the following command in the terminal interface:
    fsck -fy
    3- Then you have to mount the root drive with write option enabled so you can apply and save any changes. Type this in the temrinal interface:
    mount -uw /
    4- And then type this command exactly as you see it here:
    rm /var/db/.AppleSetupDone
    5- Reboot your MBA by typing this in the terminal interface:
    reboot
    6- After you reboot, you will be see the “Welcome Wizard” startup screen. Follow the wizard and create a new user account. This new account name must be different from the one you already have
    7- Continue and boot into your Mac OS X with the new account you have just created, this new user account is an Administrator and has administrative access
    8- Now that you're logged in, go to System Preferences
    9- Click on Users & Groups
    10- Click on the Lock icon and use your newly created user name and password if asked. This will allow you to make changes to other user accounts
    11- On the user panel select the user account whose password you cannot change and then click on the Change Password... button and enter your new password.
    12- Delete, or grant administrative privileges to that old account
    13- Reboot/restart your MBA and now you can log back in with your old account. If you want you can delete the user account you created following this steps.
    Hope this helps.
    Good luck

  • IMac is asking for admin login password upon startup when it never did before, settings are still on auto login. Why is it doing this out of the blue?

    Is sounds like it might for some reason booting into Safe Mode, which does prompt for a password.
    Try a PRAM reset:
    Shut down the computer.
    Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
    Turn on the computer.
    Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
    Hold the keys down until the computer restarts and you hear the startup sound for the second time.
    Release the keys.
    If that doesn't help, restart holding down the option key which should take you to the startup manager. Select Macintosh HD (you may need to use the arrows on the keyboard if the kb is Bluetooth), tap 'enter'. Does it boot normally now?

  • Invalid Login Credentials

    I am working on my application and can work on the pages but when I try and log in and run them I'm getting the "Invalid Login Credentials" message. It worked fine Friday and when I got to work this morning it wouldn't run. Any ideas? Help!

    We are getting a blade in approx. two week which will be dedicated to Apex and I will be setting up the production environment. I'm curious about how to set up a development vs. production area and security issues as well. I think Craig and Ron will be here tomorrow and I'll broach the subject with them.

  • Login credentials server with multiple users on 1 Mac

    The situation is a MacBook Pro running Mountain Lion connecting to a Mac Mini.
    The MacBook Pro has 3 users with administrator rights:
    A, B and C.
    When user B is logged in and wants to connect to the Mac mini, the login dialog shows the credentials of user A by default.
    This happens also after a re-start and first login by user B.
    How can I have the system forget the login credentials in the above case so that user B can have the correct default user name in the login window?
    Thanks for your help.

    While logged in as User B, open Keychain Access. Find the password entry for connecting to the mini and delete it.
    Then, try to log in again. User B likely used User A's login info at some point, maybe testing, to connect to the mini, so those credentials were saved in the keychain.
