trace all the particular user login sessions
How to trace all the particular user login sessions?
Need to generate a trace so that I can see whence connections machine.
user account is already locked.Audit connections without success being the natural method to accomplish this task, it might be useful to you to explain why you can't use it. It would be much easier to solve the problem of verification without verification.
If you can not really enable auditing, I guess that you can create a connection logged successful connections trigger (it would be easier to verify successful connections, but we'll assume is not authorized as well) and that cross with the listener log. Incorrect passwords would generate an entry in the log of the listener and not in the table of successful connection. Which is not exactly a simple solution to the problem, but it does not avoid using the Oracle auditing feature.

DB connection - user SYS with wrong password
Hi all
One strange thing I noticed with the SYS user as Oracle 9i (who has never worked on earlier versions), it is that I can connect to SYS as SYSDBA with wrong password user as well! Please guide how to avoid this...
(I have looked for a solution online but could not find any :())
* 009 *.SQL> CONN SYS/AAA@TEST AS SYSDBA Connected. SQL> DISC Disconnected from Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - Production With the Partitioning, OLAP, Data Mining and Real Application Testing options SQL> CONN SYS/BBB@TEST AS SYSDBA Connected.

There is nothing wrong, and nothing should be, IMO, prevented.
When you connect to the server as a user in the Group dba (Unix) or group ora_dba (Windows), you are an advanced user and authentication of the o/s applies to you, and you don't need a password .
Login as the owner of the software (oracle) all the time, what do many DBA, is a bad idea in any case, you can remove anyufile o/s level.Strategies to avoid it:
-Make sure that your account is not in the groups I mentioned
or
-disable authentication of the o/s of editiing sqlnet.oraThe two procedures are documented.
Finally, note someone who has root access can move easily.

Successive connection LDAP fails after the first LDAP authorization: with wrong password
Hello
I am currently integration Oracle CC & B utility to LDAP (Sun Directory Server java - SunOne), but I made a post here because CC & B delegates the task of authentication to the server Weblogic (I user WLS version 10).
In Weblogic, I configured two authentication providers:
1. the principal is the LDAP authentication provider (defined as optional control indicator)
2. secondary education is the default authentication provider (defined as optional control indicator)
Currently, some users of CC & B are stored in LDAP, and some other (more users system) are stored in the default authentication provider.
To help you make the problem more clear, I did the test with followingscenario:
1. user LDUser2 (stored in LDAP) login with correct passwrod-> success
2. the sysuser user (stored in the default authentication provider) connect with incorrect password-> access denied (what is good and normal)
3. the LDUser2 (stored in LDAP) user login with password-> successful OK
4. the sysuser user (stored in the default authentication provider) connect with correct password-> successful OK
5. the user (stored in LDAP) LDUser2 connect with the incorrect password-> denied access, which is normal. However, from this point, the problem starts
6. the user (stored in LDAP) LDUser2 connect with the right password-> rejected access KO is the problem
7. connection (also stored in LDAP as LDUser2) LDUser1 with the right password of the user-> big problem of access denied KO
8. the LDUser7 user (stored in the default authentication provider) connect with the right password-> successful access
9 restart the server resets the situation, but once a user is stored in the LDAP connection with a wrong password (5 point number), attempts by users stored in LDAP fail.
It seems that after the first LDAP authentication with wrong password, all users stored in LDAP connection attempts will fail.
Help, please.
Thank you.
JeffryHello
The connection attempt is made on console weblogic with the same result?
If I'm not wrong, until WLS 10.3 it is a problem reported where once the user connects with password and username incorrect, all attempts after that results in the failure of the connection.
The patch is available with up to 10.3 WLS support
This might be the question however need to check.

My wife is the administrator user and she forgot her password and it does not back up and there is only standard users on this PC, what can we do?
If your wife was using his account with "computer administrator" privileges, and then use the built-in account named "Administrator".
By default, the built-in account named "Administrator" doesn't have a password. If you have XP Pro, you can access the administrator account (with no other connected users) Welcome screen by pressing CTRL + ALT + DELETE twice to bring up the "classic" logon window Enter the administrator user and leave the password empty box.
In XP Pro or XP Home, you can access the administrator account by restarting mode without fail (repeatedly press F8 to leave immediately after the computer starts / restarts; if you see the Windows logo, you waited too long and you will need to try again). Once Windows starts in Mode safe mode, the administrator account will appear on the Welcome screen.
Once you are in the administrator account, go to control panel > user accounts to reset the password of an account with "computer administrator" privileges or create a new user account with privileges "computer administrator."
If the password that you lack to the built-in, ' administrator' account politics of Microsoft for these forums forbid us to provide you with any information that might help you to bypass this password.

Microsoft FixIt fails with the error 0x80004005 when run in the Standard user login
Microsoft recommends running in a Standard user login. However, the FixIt will not work in a Standard user login, even if started with "Run as Administrator".

The purpose of running two separate is Windows Live Mail accounts to have total privacy on each, avoiding different users can see other accounts or e-mail folders. I don't want to mix the different user accounts when the opening of windows live mail, each user must be able to open his account separately.
ThxsWhile this was possible with Outlook and Outlook Express identities as this function is not available with Windows Live Mail as detailed here
Basically, it says to put in place of the separate accounts for each user to connect to Windows to isolate the e-mail accounts in each of the other opinions.
On the only other option is to use some use webmail ISP provides you instead of Live Mail.

SlateBookx2: I closed my session with wrong password and I can connect is no longer
Hey,.
I blocked my Slatebook session with my usual password before you turn it off. I must have typed wrong twice. Earlier this afternoon, I went from the Tablet, entered the password, and the display shows "wrong password". I've tried dozens of variants (including the cap lock), nothing works.
Is there a way to reset everything, even if that means reformatting of the Tablet?
Any suggestion is appreciated.
Thank you
Hi Sapiens,
I would off the tablet of the keyboard if you are only working with the tablet. Try now the power button and selecting "Power Off" when it appears on the screen. Once the unit is off, follow these instructions to reset the unit to the power off state: factory reset instructions.
Please mark this message as the accepted answer if I solved it your problem.
Thank you

How to kill an Open Directory - password be reset when the first user login
Hi all
I've been running on this issue for some time now, however, I finally got tired of it. I want to set a password policy, but the option 'Reset password on the first login of the user' completely kills OpenDirectory.
Running OS X Server 10.11.3 and 5.0.15, although this has happened also in versions of Yosemite. This case is a new and clean installation in a virtual machine. Only OpenDirectory and appropriate DNS are enabled. DNS was fully configured by the Server app when you set the hostname and checks in the Terminal.
I created a few test users OpenDirectory and confirms that I can not connect with them. Can I put another option in the strategy of password very well, however, the minute I turn on 'reset the password on the first login of the user', my OpenDirectory is ruined.
I'm unable to add new users, I am unable to change passwords, policies of previous password, I had set is no longer working. That is, the user cannot change password when you sign in for the first time. Correct password is entered, but shakes the login window when you try to configure the new password.
Error returned once the OpenDirectory gets watered is "Mode is not supported by the node directory. Not only is the directory watered, but it becomes difficult to even remove or disable the hella service.
Someone at - it ideas? I really want to enable this feature so that I'm not creating a temporary password for users, then relying on them to change themselves.
Thank you
It always seems to be the case - the diradmin account gets completely borked. Have you already found a way to define this strategy successfully?
This command will unlock the overall strategy and restore the account, so you can use OD once again, but it's just a solution, not a solution.

You would browse the information stored in the $result variable.
$result = $con-> query ("SELECT ALL * from newrequest where Fname ="$User"" ");
As below:
fetch_assoc()) {? >}
(I don't see a reason to assign data to a variable of $_SESSION?)
You also probably would be well advised to select information based on a uniquie rather than a name id - if two people have the same name youre UNLESS you want to make sure that two identical Fname can be stored in your tabe stuffed.
$result = $con-> query ("SELECT ALL * from newrequest where userID = '$userID'");
userID | Fname | Location | Description

Is the program "Clairvia' (login) compatible with MOZILLA FIREFOX?
Recently, I removed my IE9 and installed Mozilla Firefox. Clairvia is the program that I use at the entrance to my schedule for the work. Since the evolution of IE 9, Firefox, when I log in the program of Clairvia I am not able to access. It doesn't let me do the things I need to do. you have all the answers? Any help?
http://clairvia.hackensackumc.NET/
What version of Windows do you have? I don't know that IE is still there somewhere. If you can't find a shortcut anywhere, try typing this in the start menu > run or start > Search box:
iexplore.exe
With regard to this web application, because a connection is required, has no way for volunteers of the forum to take a look. You can check with your company on if they take over Firefox for this application?
If you want to explore on your own, try the site Firefox Safe Mode. It is a standard diagnostic tool in order to avoid interference by extensions (and some custom settings). More info: questions to troubleshoot Firefox in Safe Mode.
You can restart Firefox in Mode safe help
Help > restart with disabled modules
In the dialog box, click on 'Start mode safe' (not Reset)
Any difference?
