Root Password Doesn't Work on Sudo Commands

I went through the process of changing the root password in Recovery mode and it appeared everything went as expected. Rebooted the Mac. When I run a command in Terminal using "sudo", I get challenged for the root password, and authentication fails. Are there any reasons that might explain this, or is there something I need to do differently? The laptop is supplied by my work, and I have both an admin and a standard account on it. When I'm prompted for admin authentication, entering the admin username and password works fine. But I need to be able to do things that require sudo permission (like reload the hosts file without having to do a full reboot), and it's just not responding to the password I just reset. Thanks for any help.

Does your work know you enabled the root password on their hardware? They may consider that a security risk it isn't normal for Mac users to do this and it defeats the point of having sudo installed too.
Read the manual…
https://developer.apple.com/library/mac/documentation/Darwin/Reference/ManPages/ man8/sudo.8.html
man sudo
(NOTE: in the default configuration this is the user's password, not the root password).
You need to be an admin user to use sudo, standard accounts do not have access to it.

Upgraded to Mountain Lion, now my login password doesn't work

Hello,
As the title says, I upgraded my iMac with Mountain Lion, and now my password doesn't work. I can't log in to the computer at all.
And no, I didn't forget it. It's been the same since I first got it (so an unfortunate hack on wireless wouldn't be out of the question...)
Suggestions? Solutions?
Thanks

Resetting User Password in Lion, Mountain Lion & Mavericks
Boot into your Recovery Partition by hold down the Command and R keys whilst booting.
When the Recovery screen appears, go to the Utilities menu and open Terminal.
In Terminal, type:
resetpassword
...a small app will open and allow you to choose the user for whom you want to change the password. If you are the admin, be certain that you choose your admin user. Type in your new password twice and give yourself a good hint. Click OK (or Done or whatever) and reboot, enjoying the use of your new, hopefully memorable, password.
Good luck,

I cannot sign into iCloud on my iMac. I have read all of the help information, but that isn't working. I cannot do anything with my system preferences - like add a new printer - because it won't log me in, sign me out, forget password doesn't work, etc.

I have been unable to log in to iCloud on my iMac. None of the hints online have worked. I can't sign in (with any password), sign out, the forget password doesn't work, the support button doesn't work. It's locked. I can't find anyway to fix this - I need to add a new printer ASAP - help!!!

The "Mail, Contacts & Calendars" window popped up a couple of weeks ago and is asking for my Apple ID password, which it will not accept, It won't sign me out (I am not logged in), the support or forgot password buttons won't work. With this window stuck open, I cannot access anything on system preferences. I can't find any way to make it go away. I have tried both my current and old Apple ID passwords, tried using FaceTime to login with the newer password, etc.

Does anyone else have two Apple IDs? I can't get rid of one of them. It's associated with my iCloud account and I can't fix it. The password doesn't work.

So, apparently I have two Apple IDs associated with my iPhone. One is an old aol address that got hacked and was shut down. Even aol doesn't recognize the email address anymore, and the password doesn't work. It's associated with my iCloud account, so now I can't access that account. My other Apple ID is with everything associated with my iPhone and everything works just fine. But now I can't get to my iCloud stuff. Has this ever happened to anyone else. The guy at the Apple store says he's never heard of it.

Does the alert refer to "Local Items?"

I just set up my yahoo email account on Mail, but
whenever I try receive or send email Mail asks me for
my password. I enter my password, and then it tells
me that the server rejected my password. I have
checked two dozen times to make sure that I am
entering the right password. It is definitely the
right one, but the server always rejects it. When I
long on to my yahoo account on the web, my password
works fine. What am I doing wrong? I don't want to
call yahoo either because they charge you for support.
i get this all the time. i have pop forwarding with yahoo!, and it has worked well with mac mail for a couple of years - but every once-in-a-while, i get the 'password rejected' dialog box. it's really annoying.

My password doesn't work for itunes

I was wrong --- turns out I did create a password long ago for my first backup, different than my iTunes password, and fortunately I was able to remember it. The restore worked fine once I gave it the password that it wanted.

The software Sticky Password Doesn't work.

the plugin Sticky Password doesn't work in Firefox 37.

Changed the Product forum this thread is in from Thunderbird to Firefox so no need to create a duplicate thread.
This is a Extension in Firefox and not a Plugin like Flash or Java.
Also you are Testing builds on the Beta channel (currently at 37.0'''b3''') and Extensions like these tends to only support the current Release at most which is Firefox 36. www.mozilla.org/firefox/all/
In the Sticky Password software you can go to "Settings - Supported browsers and install the extension" as I guess that may be where there are updates? https://support.mozilla.org/en-US/questions/948577

In my dock there was this weird program called "tutorial". While throwing away this program I had to fill in my password. Afterwards I tried to change my password, but my old password doesn't work anymore. Who can help?

What was this program for, or did you just assume it's something you shouldn't have and therefore arbitrarily decide to "throw it away"? Exactly how did you supposedly throw it away?
If you didn't change your administrator password, there's no reason it shouldn't work now, so that suggests you did something else, or changed it and then forgot what it was.
You can't recover that password; you can only change it. To do that, you would need to boot from your Snow Leopard DVD, choose your language, then choose Reset Password from the Utilities menu in the top menu bar.

Just upgraded to 6.1 but my iTunes password doesn't work for my restore

Just backed up my iPhone4 in iTunes, transferred purchased items to my iTunes library, and then updated the IOS to 6.1. Now iTunes is giving me the option to restore from my backup, but it wants a password, and my iTunes password doesn't work! I was never asked for a new password for by backup so I'm very surprised my iTunes password doesn't work. I just logged into this forum with my iTunes password so I know it is still active. Anyone have any ideas of what I should do next? Thanks!

Parsing in Weblogic/jsp doesn't work; application-mode (command-line) works

Hello-
Parsing my XML file in Weblogic/jsp doesn't work, whereas it works
in application-mode... (albeit on two different machines)
Here are the parameters:
server1:
weblogic 6.0
win2k server
jre1.3
my personal machine:
***no weblogic***
win2k server
jre1.3
When I run my code as an application (command-line style) on my machine,
parsing in my xml file works fine, and I can do a root.toString() and it
dumps out the entire xml file, as desired.
However, running my code inside weblogic (on server1) in JSP, parsing in
my file and doing a root.toString() results in the following: [dmui: null]
(where dmui is my root)
(even though i'm running it on two different machines, i'm positive its the
same code (the servers share a mapped drive)...
So, I think its probably because I'm using a different parser, as
specified by weblogic? There are no exceptions being thrown. Here's my
(abbreviated) code, which is called either command line style or in a JSP:
// Imports
import org.w3c.dom.*;
import org.w3c.dom.Document;
import javax.xml.parsers.*;
import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.parsers.DocumentBuilder;
import org.xml.sax.SAXException;
import org.xml.sax.SAXParseException;
DocumentBuilderFactory docBuilderFactory =
DocumentBuilderFactory.newInstance();
DocumentBuilder docBuilder = docBuilderFactory.newDocumentBuilder();
mDocument = docBuilder.parse (inFile);
myRoot.toString()
-END
Doing a System.getProperty("javax.xml.parsers.DocumentBuilderFactory")
results in:
server1 (weblogic/jsp):
"weblogic.apache.xerces.jaxp.DocumentBuilderFactoryImpl"
my machine (application-mode):
null
Does anyone have any ideas about how to get this work? Do I try to set it
up so that they both use the same parser? Do I change the Weblogic parser?
If so, to what? And how?
Am I even close?
Any help would be appreciated..
Thanks, Clint

Personally I would get rid of import com.sun.xml.parser.* and use xerces
which comes with WLS 6.0 now, unless like I said earlier you have a need
to
use the sun parser :) Try something like this with your code --I've put
things to watch for as comments in the code.
import javax.xml.parsers.*;
import org.xml.sax.SAXException;
import org.w3c.dom.*;
import java.io.FileInputStream;
public class BasicDOM {
public BasicDOM (String xmlFile) {
try{
FileInputStream inStream;
Document document;
/*You must specify a parser for jaxp. You can in a simple view
think
of this as being analogous to a driver used by JDBC or JNDI. If you are
using this in the context of a servlet or JSP and have set an XML
registry
with the console this happens automatically. You can also invoke it in
the
context of an application on the command line using the -D switch. */
System.setProperty("javax.xml.parsers.DocumentBuilderFactory",
>>>
"weblogic.apache.xerces.jaxp.DocumentBuilderFactoryImpl");
// create a document factory
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
// specify validating or non-validating parser
dbf.setValidating(true);
// obtain a factory
DocumentBuilder db = dbf.newDocumentBuilder();
// create a document from the factory
inStream = new FileInputStream(xmlFile);
document = db.parse(inStream);
}//try
catch (Exception e)
System.out.println("Unexpected exception reading document!"
+e);
System.exit (0);
}//catch
}//BasicDom
// Main Method
public static void main (String[] args) {
if (args.length < 1)
System.exit(1); file://or you can be more verbose
new BasicDOM(args[0]);
}//class
=============================================
That will give you a basic DOM you can manipulate and parse it fromthere.
BTW this code
compiled and ran on WLS 6.0 under Windows 2000.
Let me know if this helped or you still are having trouble.

Actually I included com.sun.xml.parser.* as one last febble attempt toget
it working.
And as for source code, I included the code. If I just put that oneline
of code
in, including the imports, it fails giving me an error listed above inthe
subject
line. Here is the code again:

Hi, Rob
Does it work in WL9.2?
It seems I do it exactly as the explained at http://edocs.bea.com/wls/docs81/programming/classloading.html - and it fails :o(.
I try to run my app.ear with WL9.2 There are 2 components in it: webapp and mdb. The webapp/WEB-INF contains weblogic.xml:
<weblogic-web-app>
<container-descriptor>
<prefer-web-inf-classes>true</prefer-web-inf-classes>
</container-descriptor>
</weblogic-web-app>
Mdb is expected to run in the same mode, i.e. to prefer the webapp/WEB-INF/*.jar over the parent Weblogic classloader. To do so I add the weblogic-application.xml to the app.ear!/META-INF:
<weblogic-application>
<classloader-structure>
<module-ref>

<module-uri>webapp</module-uri>
</module-ref>
<classloader-structure>
<module-ref>
<module-uri>mdb.jar</module-uri>
</module-ref>
</classloader-structure>
</classloader-structure>
</weblogic-application>
Now, when classloader-structure specified, both webabb and mdb prefer the weblogic root loader as if prefer-web-inf-classes not defined at all.
